Part Number: SAV-BTE3-NO
The Dwyer SAV-BTE3-NO 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 distinction makes it suitable for applications involving elevated process temperatures, including hot water, low-pressure steam, and thermal oil.
Designed for 1-1/2" NPT piping with a 3-9/16" pneumatic piston actuator, the valve provides fast and positive on/off control in an angle-body configuration. The BT trim is intended for higher-temperature service where standard ST-body trim may not be suitable.
The normally open (NO) configuration means the valve remains open under normal 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 construction helps maintain efficient flow while reducing flow resistance and pressure drop compared with a comparable globe valve. The pneumatic piston actuator is designed for long service life under frequent cycling, making the valve suitable for applications such as batching, CIP/washdown, and thermal process interlocks.
If a normally closed configuration is required, the Dwyer range also includes the SAV-BTE3-NC, which provides the same 1-1/2" NPT connection, 3-9/16" actuator, and BT high-temperature trim in an NC configuration.
Key Benefits

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 useful where a pneumatic angle seat valve with a normally open fail position is required in a 1-1/2" NPT 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 appropriate compressed-air supply.
- Confirm the normally open behavior when pneumatic pressure is removed.
- Apply air pressure and verify that the valve closes correctly.
- Cycle the valve to confirm smooth and positive 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 remains open when pneumatic pressure is removed and closes when air 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?
It is suitable for hot water, low-pressure steam, thermal oil, and other elevated-temperature on/off process lines, including applications involving frequent valve cycling.
