Part No. SAV-BTD3-NC
The Dwyer SAV-BTD3-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 1-1/4" NPT piping with a 3-9/16" pneumatic piston actuator, the SAV-BTD3-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.
This model is part of Dwyer Instruments' SAV product range carried by GeneralTech Shop. Contact our team if you need help confirming the correct variant for your application.

- 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-BTD3-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-BTD3-NC?
The valve has a 1-1/4" NPT connection.
What actuator diameter does the SAV-BTD3-NC use?
It uses a 3-9/16" pneumatic actuator.
Is the SAV-BTD3-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-BTD3-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.
Does GeneralTech Shop deliver the SAV-BTD3-NC across the UAE?
Yes. Call +971 6 5436933 to confirm stock and delivery timelines for your emirate.
