Refrigerant Solenoid Valves

 

Solenoid Valves- SV2

This compact, heavy duty, pilot operated, ductile iron bodied solenoid valve is suitable for Ammonia, and other refrigerants, certain oils and other fluids approved for use in refrigeration.

  Product Overview

     Specification

Parker’s SV2 is a compact pilot operated solenoid valve that is ideal for liquid feed and hot gas feed applications.  The valve compact size makes it ideal for installations where limited mounting space exists.  The SV2 can be mounted on vertical lines which allows designers more freedom in the placement of the valve especially in tight quarters.  The SV2 may be opened by means of a manual opening stem for servicing or in case of an electrical power failure. The valve can be ordered with a close couple stainless steel screen strainer. The Type SV2 valve is available with an optional extension tube to raise the solenoid operator and coil housing assembly 50mm (2.0”) above the valve body to accommodate pipe Insulation. When this option is desired, the Type SV2A solenoid valve should be specified. The Type SV2 and SV2A solenoid valves can be furnished with FPT: Internal NPT (U.S. Standard Taper Pipe Thread), Socket Weld, Weld Neck, or ODS (solders over copper tubing of given diameter) connections. The valves may be easily removed from between the flanges for servicing. The SV2 is a spring closing, normally closed solenoid valve.
