Part Number: SAV-STB1-NC
The Dwyer SAV-STB1-NC is designed for demanding process applications that require reliable 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. When air pressure is removed, 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 designed for dependable operation during frequent cycling, making the valve suitable for applications such as batching, washdown, and process interlocks.
The SAV-STB1-NC features stainless steel wetted parts and a PTFE seat, supporting broad compatibility with process media. Its compact actuator footprint also makes it practical for installation in existing skids, panels, and process equipment where space may be limited.
This model is part of the Dwyer Instruments angle seat valve range supplied by GeneralTech Shop. Contact our team if you need help confirming that this configuration is suitable for your application.
