Parker P-Series Control Valves PA4C & PS4C

The PA4C/PS4C weld-in line series solenoid valves are designed to overcome corrosion problems encountered in harsh environments. Being weld-in, the valves reduce the potential for connection leaks and can be entirely serviced from the top. These valves provide long-term performance and with replaceable internal components. Specially designed wear rings eliminate the need for removal of the body from the line (maintenance-free).
