Refrigerant Solenoid Valves

 

Solenoid Valves S8F and S6N

The S6N & S8F Solenoid Valves are compact, heavy duty and are suitable for Ammonia and other common refrigerants for liquid lines, refrigerant oil lines, and as a pilot valve to actuate remote gas powered valves and other pilot actuated devices.

  Product Overview

     Specification

A solenoid valve is an electrically operated device used to control the flow of liquids or gases in a fully open or fully closed configuration. The S6N & S8F are normally closed solenoid valves to control the flow of refrigerant. Like all Refrigerating Specialties Solenoid Valves, these valves do not modulate. When electrically energized, they open wide; when de-energized, the valves close to stop flow in the normal direction. The S8F is direct acting; the valve needle is lifted and held open electrically by the solenoid coil. No pressure drop or flow is required to open or hold open this valve. Thus, the S6N Solenoid Valve is ideal for use as a pilot solenoid valve. The S8F is a pilot operated valve which features a higher flow capacity than the S6N. Both valves are available with ductile iron or stainless steel bodies.
