Part Number: SAV-BTE3-NO
The Dwyer SAV-BTE3-NO carries Dwyer's BT high-temperature body trim, using PTFE and FKM sealing materials instead of the standard NBR seals used on the ST-body SAV range. This makes it suitable for process lines carrying hot water, low-pressure steam, thermal oil, and other elevated-temperature media where standard ambient-temperature service is not sufficient.
Sized for 1-1/2" NPT piping and equipped with a 3-9/16" pneumatic piston actuator, the SAV-BTE3-NO provides fast, positive on/off control in an angle-body design. The BT trim is intended for the higher service temperatures associated with hot process applications.
The valve's normally open configuration means it remains open under unpowered conditions. When pneumatic pressure is applied, the valve closes. This fail-open behavior can be useful for process interlocks and applications where continued flow is required when air pressure is lost.
The angle-body design helps maintain efficient flow while keeping flow resistance and pressure drop lower than a comparable globe valve. The piston actuator is designed for long service life under frequent cycling, making the SAV-BTE3-NO suitable for batching, CIP/washdown, and thermal process interlock applications.
For applications requiring a normally closed configuration, the Dwyer SAV-BTE3-NC provides the same 1-1/2" NPT size, 3-9/16" actuator, and BT high-temperature trim with NC operation.

Who This Product Is Best For
The Dwyer SAV-BTE3-NO is suited for process and utility engineers working with hot water, low-pressure steam, thermal oil, and other elevated-temperature process lines. It is particularly applicable where a pneumatic angle seat valve with a normally open fail position is required for a 1-1/2" NPT process system.
How to Use
- Install the SAV-BTE3-NO in the process line using the 1-1/2" NPT connection.
- Connect the pneumatic actuator to the compressed-air supply.
- Confirm that the valve remains open when pneumatic pressure is removed.
- Apply air pressure and verify that the valve closes correctly.
- Cycle the valve to confirm smooth and positive on/off operation before commissioning it on hot service.
Frequently Asked Questions
What makes the SAV-BTE3-NO different from standard ST-body SAV valves?
The SAV-BTE3-NO uses BT high-temperature trim with PTFE/FKM sealing materials, making it suitable for elevated-temperature applications such as hot water and low-pressure steam.
What is the NPT size of the SAV-BTE3-NO?
The valve has a 1-1/2" NPT connection.
What actuator diameter does the SAV-BTE3-NO use?
It uses a 3-9/16" pneumatic actuator.
Is the SAV-BTE3-NO normally open or normally closed?
It is normally open (NO). The valve stays open when unpowered and closes when pneumatic pressure is applied.
What seal material does the SAV-BTE3-NO use?
The valve uses PTFE/FKM high-temperature sealing materials.
What applications suit the SAV-BTE3-NO?
The valve is suitable for hot water, low-pressure steam, thermal oil, and other elevated-temperature on/off process lines, including applications involving frequent cycling.
