Description
This compact, heavy duty, direct-acting solenoid valve is
suitable for industrial refrigerants for liquid lines, refrigerant
oil lines, and as a pilot valve to actuate remote gas powered
valves and other pilot actuated devices. The plunger-needle
assembly is also used with most other Refrigerating
Specialties industrial solenoid valves. This valve is usually
ordered with a close-coupled stainless steel screen strainer.
(See page 436 for strainer information).
