Solenoid Valves - S7A, S7AL, S7F
Brand: Parker - Fluid Control DivisionType S7A is a very versatile pilot operated, positive lift, solenoid valve that may be used in most liquid, or hot gas lines.
Parker’s S7 series solenoid valves are available in a low pressure drop version that are capable of opening with a pressure drop less than 1 psi across the valve.
This feature makes them ideal for applications where low pressure drop is important, such as low pressure liquid feed lines. The S7 is a pilot operated, positive lift, cast iron bodied valve.
The valve may be opened by means of the manual opening stem for servicing or in case of electrical power failure.
The Type S7 Solenoid Valve is furnished with FPT Internal NPT (U.S. Standard Taper Pipe Thread), Socket Weld, Weld Neck or ODS (solder over copper tubing of given diameter) connections.
