Part No. SAV-BTF3-NC
The Dwyer SAV-BTF3-NC features Dwyer's BT high-temperature body trim, using PTFE and FKM sealing materials instead of the standard NBR seals used in the ST-body SAV range. This makes it suitable for elevated-temperature applications such as hot water, low-pressure steam and thermal oil.
Designed for 2-inch NPT piping with a 3-9/16-inch pneumatic piston actuator, the SAV-BTF3-NC provides fast, positive on/off control in an angle-body configuration. Its normally closed (NC) configuration means the valve remains closed under normal unpowered conditions and opens when pneumatic pressure is applied, providing fail-closed operation for applications where the line needs to shut off by default.
The angle-body design helps reduce flow resistance and pressure drop compared with a comparable globe valve, while the piston actuator is designed for repeated cycling in process and utility applications.
Need a different configuration? The Dwyer range also includes the SAV-BTF3-NO High-Temperature Angle Seat Valve (2" NPT, 3-9/16" Actuator, NO) for applications requiring normally open operation.

How to Install & Commission It
- Install the SAV-BTF3-NC in the process line using the 2-inch NPT connection.
- Confirm that the valve, seal materials and process conditions are suitable for the intended service.
- Connect the pneumatic actuator to the appropriate compressed-air supply.
- Verify the normally closed behavior: the valve should remain closed when pneumatic pressure is removed.
- Cycle the valve and check for smooth, positive operation before commissioning the system on hot service.
Frequently Asked Questions
What makes the SAV-BTF3-NC different from standard ST-body SAV valves?
The SAV-BTF3-NC uses BT high-temperature trim with PTFE and FKM sealing materials, intended for elevated-temperature service.
What NPT size is the SAV-BTF3-NC?
It has a 2-inch NPT connection.
What actuator diameter does the SAV-BTF3-NC use?
The pneumatic actuator has a 3-9/16-inch diameter.
Is the SAV-BTF3-NC normally open or normally closed?
It is normally closed (NC). The valve remains closed when unpowered and opens when pneumatic pressure is applied.
What applications suit the SAV-BTF3-NC?
The supplied product information identifies hot water, low-pressure steam, thermal oil and other elevated-temperature on/off process lines as suitable applications.
What are the seal materials?
The high-temperature trim uses PTFE and FKM sealing materials.
What are the wetted parts?
The supplied specification lists stainless steel wetted parts.
Does GeneralTech Shop deliver the SAV-BTF3-NC across the UAE?
Yes. Call +971 6 5436933 to confirm availability and delivery timelines to your emirate.
Should I choose the SAV-BTF3-NC or SAV-BTF3-NO?
Both models use a 2-inch NPT connection, BT high-temperature trim and a 3-9/16-inch actuator. The SAV-BTF3-NC provides normally closed operation, while the SAV-BTF3-NO provides normally open operation.
