Dwyer Instruments SAV-STA1-NC | Angle seat valve | 1/2" NPT | 1-3/4" actuator dia.
Genuine Dwyer SAV-STA1-NC angle seat valve from General Tech Services LLC, Saudi Arabia, with free Saudi Arabia shipping available.
Part No. SAV-STA1-NC
Product Overview
The Dwyer SAV-STA1-NC is a compact, externally piloted stainless steel angle seat valve designed for reliable on/off control of compatible gases, liquids and steam. It features 1/2" NPT female connections, a 1-3/4" single-acting pneumatic actuator and mechanical spring return.
The valve is normally closed (NC). The mechanical spring holds the valve closed, while pilot air opens it. This spring-return configuration provides automatic closure when pilot air is removed.
The wetted components are constructed from AISI 316L stainless steel, with a PTFE seat and seal and an FKM stem O-ring. The valve provides ANSI Class VI shut-off performance and is suitable for temperatures from −10 to 180 °C (14 to 356 °F).
For applicable liquid applications, the SAV-ST series incorporates an anti-water-hammer design for bi-directional normally closed configurations where liquid flows under the seat. An integral heat sink helps protect the polyamide actuator from process heat.
The valve can be mounted in any position, while the actuator housing rotates through 360° to provide convenient positioning of the pilot ports. A visual indicator provides a quick indication of whether the valve is open or closed.
For pressure-critical applications, confirm the maximum line-pressure rating for the exact SAV-STA1-NC size and actuator combination before ordering.

How to Install & Use It
- Install the valve in the process line according to the flow direction shown on the valve body.
- Mount the valve in a suitable position and rotate the actuator housing as required to provide convenient access to the pilot ports.
- Connect clean pilot air at a minimum pressure of 60 psi.
- Connect the pilot supply directly or through a suitable solenoid valve.
- Apply pilot air to open the normally closed valve.
- Check the visual position indicator and inspect the connections and seals for leakage during commissioning.
- Confirm that the process media, pressure and temperature are within the requirements of the exact valve configuration.
Frequently Asked Questions
What size is the Dwyer SAV-STA1-NC?
The valve has 1/2" NPT female ports and a 1-3/4" actuator.
Is it normally open or normally closed?
It is normally closed (NC). The mechanical spring holds the valve shut, and pilot air opens it.
What is the valve body made of?
The body, plug and stem are made from 316L stainless steel, with a PTFE seat and seal and an FKM stem O-ring.
What media can the valve handle?
The valve is intended for compatible gases, liquids and steam. Always verify media compatibility with the wetted materials and operating conditions.
What is the temperature range?
The specified temperature range is −10 to 180 °C (14 to 356 °F).
What is the maximum steam pressure?
The Series SAV datasheet specifies a maximum steam pressure of 150 psi. Confirm the complete pressure rating for the exact configuration before ordering.
What is the minimum pilot pressure?
The minimum pilot pressure is 60 psi.
Can the valve be mounted in any orientation?
Yes. The valve can be mounted in any position, and the actuator housing rotates through 360° to help position the pilot ports.
Should I choose the SAV-STA1-NC or SAV-BTF3-NO?
Selection should be based on the required line size, body material, actuator configuration, operating conditions and fail-safe position. Provide your media, pressure and temperature requirements so the appropriate configuration can be confirmed.
Is delivery available across Saudi Arabia?
Yes. Free Saudi Arabia shipping is available. Call +966 569 289 544 for pricing and lead-time information.
