Dwyer Instruments SAV-STC3-NO | Angle seat valve | 1" NPT | 3-9/16" actuator dia.
The Dwyer SAV-STC3-NO is a pneumatically actuated normally open angle seat valve designed for reliable on/off process control. Featuring a 1" NPT connection and 3-9/16" actuator, it provides fast, positive control for steam, water, air, and general process lines.
Its normally open (NO) configuration keeps the valve open under normal unpowered conditions and closes when pneumatic pressure is applied, providing fail-open behavior for applications where maintaining flow during loss of air pressure is required.

Part Number: SAV-STC3-NO
The Dwyer SAV-STC3-NO is designed for demanding process applications requiring dependable pneumatic on/off control and repeated valve cycling. Its 1" NPT connection makes it suitable for compatible process piping, while the 3-9/16" pneumatic piston actuator provides positive and consistent valve operation.
With its normally open configuration, the valve remains open when pneumatic pressure is removed and closes when air pressure is applied. This fail-open behavior can be useful in process interlocks and other systems where continued flow is required during a loss of pneumatic pressure.
The angle-body design provides an efficient flow path and can help reduce flow resistance and pressure drop compared with a conventional globe valve of similar size. The piston actuator is designed for reliable operation in applications involving frequent cycling, such as batching, washdown, and process control systems.
The valve features stainless steel wetted parts and a PTFE seat, supporting use with a broad range of compatible process media. Its compact actuator footprint also makes the valve practical for installation in existing equipment, skid systems, and control-panel layouts.
The SAV-STC3-NO is part of Dwyer Instruments' angle seat valve range supplied by GeneralTech Shop. If you need assistance confirming the correct variant for your application, contact the team before ordering.
