Part No. SAV-BTB1-NC
The Dwyer SAV-BTB1-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 hot water, low-pressure steam and thermal-oil service where higher temperature resistance is required.
Designed for 3/4" NPT piping with a 1-3/4" pneumatic piston actuator, the SAV-BTB1-NC provides fast, positive on/off control. Its NC configuration keeps the valve closed under normal unpowered conditions and opens when pneumatic pressure is applied, providing fail-safe shutoff for suitable process applications.
The angle-body design helps reduce flow resistance and pressure drop compared with a comparable globe-style valve, while the piston actuator is designed for reliable operation under frequent cycling.
Need a different specification? The Dwyer range also includes the SAV-STB1-NC, a 3/4" NPT angle seat valve with a 1-3/4" actuator and NC configuration, allowing you to match the valve to your application requirements.

How to Install & Commission It
- Install the SAV-BTB1-NC in the process line using the 3/4" NPT connection.
- Confirm that the valve materials and BT high-temperature trim are suitable for the process medium and operating conditions.
- Connect the pneumatic actuator to the appropriate compressed-air supply.
- Verify the NC configuration and confirm that the valve closes when air pressure is removed.
- Cycle the valve several times to verify smooth and positive on/off operation before commissioning it on hot service.
Frequently Asked Questions
What makes the SAV-BTB1-NC different from the standard ST-body SAV valves?
It uses BT high-temperature trim with PTFE and FKM seals, making it suitable for hot water, low-pressure steam and thermal-oil service beyond the standard NBR-sealed ST-body applications.
What NPT size is the SAV-BTB1-NC?
The valve has a 3/4" NPT connection.
What actuator diameter does the SAV-BTB1-NC use?
It uses a 1-3/4" pneumatic actuator.
Is the SAV-BTB1-NC normally open or normally closed?
It is normally closed (NC), meaning it remains closed without pneumatic actuation and opens when air pressure is applied.
What applications suit the SAV-BTB1-NC?
It is intended for elevated-temperature on/off applications such as hot water, low-pressure steam and thermal-oil lines, subject to the applicable operating conditions.
Should I choose the SAV-BTB1-NC or the SAV-STB1-NC?
Both models have a 3/4" NPT connection, 1-3/4" actuator and NC configuration. The SAV-BTB1-NC uses high-temperature BT trim with PTFE/FKM seals for hot-service applications, while the standard ST-body version is intended for applications within its specified service limits.
