Part Number: SAV-STD3-NC
The Dwyer SAV-STD3-NC is designed for demanding process applications that require dependable pneumatic on/off control and fail-safe shutoff. Its normally closed configuration keeps the valve closed under normal, unpowered conditions and opens when pneumatic pressure is applied. If air pressure is lost, the valve closes, helping provide automatic shutoff at critical process points.
The angle-body design provides an efficient flow path and can reduce flow resistance and pressure drop compared with a standard globe valve of similar size. The pneumatic piston actuator is suitable for applications involving frequent cycling, including batching, washdown, and process interlock systems.
The valve features stainless steel wetted parts and a PTFE seat, providing broad compatibility with process media. Its compact actuator footprint also makes the valve practical for installation in existing skids, panels, and process equipment layouts.
If you require a different operating configuration, the Dwyer range also includes the SAV-STD3-NO, which has the same 1-1/4" NPT connection and 3-9/16" actuator but uses a normally open configuration. This allows you to select the appropriate valve configuration for your process requirements.

Who This Product Is Best For
The Dwyer SAV-STD3-NC is suitable for process and utility engineers, industrial automation professionals, maintenance teams, and control contractors requiring a rugged pneumatic on/off valve for 1-1/4" NPT process lines.
It is particularly suitable for applications where the valve needs to remain closed when pneumatic power is unavailable, including batching, washdown, process interlocks, and general process shutoff applications.
How to Use
- Install the SAV-STD3-NC in the process line using the 1-1/4" NPT connection.
- Connect the 3-9/16" pneumatic actuator to a suitable compressed-air supply.
- Verify that the valve remains closed when pneumatic pressure is removed.
- Apply pneumatic pressure to open the valve.
- Cycle the valve to confirm smooth and positive on/off operation.
- Verify the complete installation before commissioning the process system.
Frequently Asked Questions
What is the NPT size of the SAV-STD3-NC?
The valve has a 1-1/4" NPT connection.
What actuator diameter does the SAV-STD3-NC use?
The valve uses a 3-9/16" pneumatic actuator.
Is the SAV-STD3-NC normally open or normally closed?
The SAV-STD3-NC is normally closed (NC). It stays closed until pneumatic pressure is applied to open it.
What materials are used in the SAV-STD3-NC?
The valve has stainless steel wetted parts and a PTFE seat.
What applications suit the SAV-STD3-NC angle seat valve?
It is suitable for pneumatic on/off control in steam, water, air, and general process lines, including batching, washdown, and process interlock applications.
What is the difference between the SAV-STD3-NC and SAV-STD3-NO?
Both models have a 1-1/4" NPT connection and 3-9/16" actuator. The SAV-STD3-NC is normally closed, while the SAV-STD3-NO is normally open. Select the configuration that matches the required process or interlock behavior.
