Accessory Valves
Pressure Limiting Valve
Pressure Limiting Valve Recommended for use in single acting systems only. Direct acting, poppet style, adjustable, cartridge type construction. Cartridge may be installed directly into your manifold. All pressure limiting valve configurations are designed to operate with up to 5,000 psi on the inlet (P) port. Seal Material: Internal seals are nylon. Internal adjustment discourages tampering with pressure adjustment setting. Two-port design eliminates need for third fluid line to drain bypass flow (internal leakage) back to system reservoir. n Recommended Filtration: 25 Micron (NOM) / 40 Micron (ABS) (minimum). a Normally Open (N/O) pressure control device. The valve remains open and fluid flows freely to downstream devices (from the valve to devices) until the pressure in the valve reaches the pressure (adjustable) set-point. At set-point pressure the valve closes, blocking further flow and pressure rise to the downstream devices. The internal valve seal Operation: The Pressure Limiting Valve (PLV) is
