Part Number: SAV-BTC3-NO
The Dwyer SAV-BTC3-NO carries Dwyer's BT high-temperature body trim, using PTFE and FKM sealing materials in place of the standard NBR seals found on the ST-body SAV range. This makes the valve suitable for applications involving hot water, low-pressure steam, thermal oil, and other elevated-temperature process media rather than standard ambient-temperature service.
Sized for 1" NPT piping with a 3-9/16" pneumatic piston actuator, the SAV-BTC3-NO provides fast, positive angle-body on/off control. Its BT trim is designed for the higher service temperatures associated with hot process applications.
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 in process interlocks and applications where continued flow is required when air pressure is lost.
The angle-body design helps reduce flow resistance and pressure drop compared with a comparable globe valve. The pneumatic piston actuator is built for long service life under frequent cycling, making the SAV-BTC3-NO suitable for applications such as batching, CIP/washdown, and thermal process interlocks.
The SAV-BTC3-NO is part of Dwyer Instruments' BT high-temperature angle seat valve range. If you need assistance confirming the correct configuration for your application, contact GeneralTech Shop before ordering.

Who This Product Is Best For
The Dwyer SAV-BTC3-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 suitable where a pneumatic angle seat valve with a normally open fail position is required in a 1" NPT system.
How to Use
- Install the SAV-BTC3-NO in the process line using the 1" 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-BTC3-NO different from standard ST-body SAV valves?
It 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-BTC3-NO?
The valve has a 1" NPT connection.
What actuator diameter does the SAV-BTC3-NO use?
It uses a 3-9/16" pneumatic actuator.
Is the SAV-BTC3-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-BTC3-NO use?
The valve uses PTFE/FKM high-temperature sealing materials.
What applications suit the SAV-BTC3-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.
