Part Number: SAV-STE3-NC
The Dwyer SAV-STE3-NC is designed for demanding process applications where dependable pneumatic on/off control and fail-safe shutoff are required. Its normally closed configuration keeps the valve closed under unpowered conditions and opens when pneumatic pressure is applied. If air pressure is lost, the valve returns to the closed position, 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 operations.
The valve features stainless steel wetted parts and a PTFE seat, providing broad compatibility for a range of process media. Its compact actuator footprint also makes it practical for installation within existing skids, panels, and process equipment layouts.
The SAV-STE3-NC is part of the Dwyer Instruments angle seat valve range available through GeneralTech Shop. Contact our team to confirm whether this configuration matches your application requirements.
