Part Number: SAV-BTB2-NO
The Dwyer SAV-BTB2-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 difference is important for applications involving hot water, low-pressure steam, thermal oil, and other elevated-temperature process media rather than ambient-temperature air or water.
Sized for 3/4" NPT piping with a 2-1/2" pneumatic piston actuator, the valve delivers fast, positive angle-body on/off control while providing the temperature capability associated with the BT trim.
Its normally open (NO) configuration means the valve remains open under normal unpowered conditions and closes when pneumatic pressure is applied. This fail-open behavior can be useful for process interlocks where maintaining flow after a loss of air pressure is required.
The angle-body design helps keep 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-BTB2-NO suitable for applications such as batching, CIP/washdown, and thermal process interlocks.
This model is part of Dwyer Instruments' high-temperature angle seat valve range carried by GeneralTech Shop. Contact our team if you need assistance confirming that this is the correct variant for your application.

Who This Product Is Best For
The Dwyer SAV-BTB2-NO is suited for process and utility engineers running 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 3/4" NPT system.
How to Use
- Install the SAV-BTB2-NO in the process line using the 3/4" 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 verify smooth and positive on/off operation before commissioning it on hot service.
Frequently Asked Questions
What makes the SAV-BTB2-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 beyond the standard NBR-sealed ST body's typical service range.
What is the NPT size of the SAV-BTB2-NO?
The valve has a 3/4" NPT connection.
What actuator diameter does the SAV-BTB2-NO use?
It uses a 2-1/2" pneumatic actuator.
Is the SAV-BTB2-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-BTB2-NO use?
The valve uses PTFE/FKM high-temperature sealing materials.
What applications suit the SAV-BTB2-NO?
It is suitable for hot water, low-pressure steam, thermal oil, and other elevated-temperature on/off process lines, including applications involving frequent cycling.
