Frequently Asked Questions
Do you provide training?
Yes, we do. We can provide training in a variety of ways from webinars to onsite training at a distributor or end-user level. The training can be sales or operations oriented.
What is your return policy?
We are a very customer service-oriented company so we will work with you on returns.
What is your warranty?
Our standard warranty is 1 year from date of shipment.
What are your minimum order requirements?
We don't have one. When a customer needs something they need it.
What unique products do you have (different from other suppliers)?
Our uniqueness is much envied and never duplicated. We can offer a complete valve package based on application details or interchange based on another manufacturer's part number. We also offer customized mounting hardware so we can supply just an actuator and mounting kit for a retrofit if the valve is still working. Lastly, we have a suite safety products that includes FM approved fusible link valve packages, spring return handles, and lock-out mounting kits.
When quoting an automated package: Is that the price for everything (included)?
Yes, unless the quote specifically states otherwise, we will assembly all the components on an order. All assemblies are tested before they ship too.
How do you ship internationally?
All international shipments are crated with man-made materials complying with international standards.
What are your shipping and receiving hours?
Our shipping and receiving hours are 8am to 4:00pm M-F.
I don't know anything about valves. How do I sell them?
We can teach you the basics fairly quickly, but we will always do the heavy lifting. We have a variety of resources like application sheets, videos, and a great technical sales team to help. We can also work with you and your customers on a joint sales call.
How does the unit operate?
The principle behind the device is simple. When a fusible link reaches its designed temperature failure point, the link will separate allowing the spring pack to close the valve.
Why do I need to replace links on a yearly basis?
The fusible links are under constant tension to hold the spring pack so to avoid premature failures, a yearly change out is recommended by the link manufacturer.
What kind of valve is used with the assembly?
Any ¼ turn API 607 approved valve is an ideal choice to be paired with our assembly. The API 607 fire rating is key here. Once the initial seat burns away the secondary seating of the API 607 fire rated valve will keep the media from getting downstream and feeding a fire or releasing media.
Can the valve still be operated manually?
Yes, it can. The LT & MT series ball valves packages can be operated with a simple turn of the handle while the device is still armed. The larger series and all packages with butterfly valves will need to be disarmed before manually operation can occur. We have a great series of videos showing this on our YouTube channel, http://www.youtube.com/user/bitorqusa.
What kind of valves do you offer with your packages?
BI-TORQ offers the FLP (Fusible Link Package) model which includes 1/4" to 2" NPT or socket weld valves or ½" to 6" valves with 150# ANSI class flanges. Both are available in stainless or carbon steel.
Can I use another valve other than what is offered in your FLP packages?
Yes, one of the great advantages of the product is that we can mount these to a specified valve of your choice. You can send us the valve to our facility for mounting or you can work with a BI-TORQ salesperson to find a valve to suit your needs.
In what kind applications would you use this type of device?
We frequently hear about new applications. Backup generators, maritime vessels, hospital oxygen lines, storage tanks, fire suppression, and day tanks are a few of the places and applications we see our product used quite frequently.
How do I know if the assembly has armed?
A good visual way to check is to make sure the links are intact on top of the unit and the red safety link is not on the assembly. BI-TORQ also offers a BOLT series proximity switch that allows for open and/or closed indication so you can monitor the device from a PLC. Please see our YouTube video or consult the installation manual for proper arming procedures.
What is the automatic firing system and how does it work?
The system incorporates an electro-thermal link in lieu of the standard link. This allows for the unit to be tripped with a low voltage signal from a control panel. The link will also operate like a standard link and will fire when the link temperature rating is met.
What is the difference between FL and FLP?
FLP stands for Fusible Link Package. This simply means it contains the valve and fusible link assembly in one ready-to-go package. They are offered in 1/4" to 2" with our FS/FW valves or 1/2" to 4" with our150# ED50/W50 valves. The FL signifies that there will be a separate line item that is either a customer-owned valve or a special valve for an application.
Can I get the valves to fail open?
We do offer all series as either fail open or fail close. You will simply need to specify at the time of quotation.
Can you do an automated variety similar to what a pneumatic actuator does?
The assemblies are not available in an automated version. We do offer a fusible plug that can be used in conjunction with a spring return pneumatic actuator. The fusible plug when used on a tee branch will vent the air in the lines and allow for the actuator to close when the plug's rated temperature is met.
What kind of remote position feedback is available?
A proximity type sensor can be added to any of our assemblies for position feedback. The sensor is mounted in the bracket area with the target mounted to the drive coupling.
Can you adjust the speed of closure so the valve shuts slower?
We are currently in development on this type of feature. We understand the importance of this particularly as it relates to larger valves and issues like water hammer. We hope to be able to offer it very soon.
What size of valves can they be used with?
Assemblies as large a 24" butterfly valves have been installed in the field. Our largest spring pack is capable of 21,390 in/lbs of torque so any 1/4 turn fire safe valve that is under that with an appreciable safety factor is viable.
Is there any maintenance involved for upkeep?
Due the link being under tension and exposed to the environment, we recommend that they replaced on a yearly basis as part of an annual maintenance program. The thought process behind the changeout is to keep them from prematurely firing as they age.
Can these be mounted on other types of valves such as globe or plug valves?
The fusible link portion of the assembly can be mounted on any 1/4 turn API 607 fire safe valve. That includes ball, butterfly, or plug valves. It does exclude multi-turn valves such as globe or gate valve due to the nature of the spring pack.
Can I provide my valve or do I have to use yours?
The fusible links are sold in two ways: a full BI-TORQ package with our fire safe valve or mounted to a customer specified fire safe valve. The valves will need to be mounted to our topworks assembly at our factory or by one of our technicians in the field.
What resources are on your web site for fusible link information?
We offer a wide range of resources on our website including sample specifications, data sheets, and product videos. Operations and maintenance manuals are also available on our website in both written and video form. We also have a Product Configurator where you will be able to download 3D models and get model specific sales drawings.
What about corrosion control on your fusible link assemblies?
We can do a number of things to help with corrosion control. As mentioned in the webinar, we offer a variety of coatings to suit specific applications. We can also offer stainless steel mounting hardware between the spring pack and valve.
Can the fire safe valve be connected to EPO control panel?
We offer an electro-thermal link that when supplied with a low voltage signal of 6-30 VAC-DC can be triggered to close a valve or a series of valves. The valves will also close when the thermal links' temperature rating is met locally. This type of assembly is not FM approved. Remote position indication is also available via a proximity sensor for any of our assemblies.
Do you have any designs for 350 bar or 5076 psi fusible links?
We have assemblies in the field with high pressure fire safe valves. a recent application was 5,000 PSI hydrogen as part of an offshore facility. The high pressure items are quoted per application so they are not part of our standard FLP packages visible on our website.
How do you take off an actuator?
Most of our assemblies are direct mount so it is just a matter undoing the bolts that go through the valve mounting pad and lifting straight up. The assemblies with mounting kits work the same way, but the bracket is bolted to the valve and the actuator.
What kind of life span can you expect out of your actuator?
There are many variables that play a part in the lifespan of an actuator, but our pneumatics have been cycle tested to 2,000,000 cycles. That will provide a very long life if the actuator is properly taken care of. Electric actuators are different in that regard, but we have seen circumstances where they have lasted a decade.
What is the difference between on-off and modulating control?
On-off control is when the actuator moves the valve from a fully open to a fully closed state or vice versa. A modulating actuator will take a control signal, typically 4-20mA, and position the valve ball or disc in intermediate positions to set a flow rate.
My customer said he wanted a 110 VAC actuator, but was quoted 115 VAC. Will it work?
Electric actuators come in industry standard voltages, but the general rule is that you can use ± 10% voltage with no issues. In this instance, the actuator will work perfectly fine.
Where do you find your valves?
The general answer is anywhere media (liquid or solid) needs to be conveyed or regulated in a piping system, or stored in a tank. That answer helps, but is quite general. Check out the application portion of our website for more insight.
