Pilot Operated Sequence Valve, SAE Flange - Series R5S R5S08-59536A1152

Parker pilot operated sequence valves series R5S enable a hydraulic system to operate in a pressure sequence. The SAE flanges allow to mount the valves directly on the outlet flanges of pumps to achieve a very compact design.

Pilot operated sequence valves series R5S are exceptional – both in function and design – even under high flow conditions. They are part of the Parker valve range with SAE flanges which is unique in its variety.

Series R5S enables a hydraulic system to operate in a pressure sequence. When the system pressure reaches the setting pressure, the valve opens and permits flow to the secondary subsystem. The SAE flanges allow to mount the valve directly on the inlet flanges of actuators or outlet flanges of pumps to achieve a very compact design.

Markets:
• Industrial

Features/Benefits:
• Proven, robust design - ensures reliable operation
• 3-port body with SAE61 flange - enables compact design
• Maximum adjustable pressure of 350 bars and flow capacity ranging from 90 l/min to 600 l/min - high performance
• Sophisticated pilot stage design - reduces pressure overshoot and cracking flow to a minimum, thus reducing heating, power and production losses at high pressure operation
• Design combines a poppet type seat valve with the pilot control - precise adjustment and quick response to eliminate pressure variation and system shocks
• Pilot operated with manual adjustment
• 3 sizes (SAE ¾", 1", 1¼")
• 3 pressure stages
