Dwyer Instruments SAV-STB2-NO | Angle seat valve | 3/4" NPT | 2-1/2" actuator dia.
The Dwyer SAV-STB2-NO is a pneumatically actuated normally open angle seat valve designed for reliable on/off process control. With a 3/4" NPT connection and 2-1/2" 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 continued flow is required during a loss of pneumatic pressure.

Part Number: SAV-STB2-NO
The Dwyer SAV-STB2-NO is designed for demanding process applications that require dependable pneumatic on/off control and consistent operation. Its 3/4" NPT connection makes it suitable for compatible process piping, while the 2-1/2" pneumatic piston actuator provides positive valve operation.
The normally open configuration means the valve remains open when pneumatic pressure is removed and closes when air pressure is applied. This fail-open behavior can be useful for process interlocks and other applications where maintaining flow is required when pneumatic power is unavailable.
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 suited to applications involving frequent cycling, including batching, washdown, and process control systems.
The valve features stainless steel wetted parts and a PTFE seat, providing broad media compatibility for suitable process applications. Its compact actuator footprint also makes the valve practical for existing equipment, skid systems, and panel layouts.
The SAV-STB2-NO is part of Dwyer Instruments' angle seat valve range supplied by GeneralTech Shop. Contact the team if you need help confirming the correct variant for your application.
