PA4 and PS4

PA4 - Inlet Pressure Regulators
PAS4C - Inlet Pressure Regulators

Inlet Pressure Regulators

The PA4 weld-in line series inlet pressure regulators are designed to overcome corrosion problems encountered in harsh environments.

The PS4 weld-in line series solenoid valves are designed to overcome corrosion problems encountered in harsh environments.

Being weld-in, these valves reduce the potential for connection leaks and can be entirely serviced from the top. The improved design has a higher working pressure, greater working temperature range and higher flow capacities than competitive products.

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).
