RG - Flui-trol Direct pressure control valves - RG-10-Z4-22-JA-J

• Direct acting type pressure adjustment valve
• Depending on the internal or external pilot pressure and drain combinations can be used as sequence, counterbalance, relief, or unload valves.
• As sequence or counterbalance valve - reverse flow from secondary side to primary side is enabled with an integrated check valve.
• As sequence valve - valve is used to control multiple actuators which operate in succession. When pressure in primary side A exceeds setting pressure, pressurized flow is delivered to secondary side B.
• As counterbalance valve - valve generates pressure in the actuator return side to prevent runaway loads caused by gravity, etc. Pressurized oil is not released until primary side A pressure exceeds the setting pressure.
• As relief valve - in addition to functioning as a safety valve to prevent excessive pressure in the circuit, it acts to maintain fixed maximum circuit pressure. Pressurized oil is released to tank when pressure in primary side A exceeds the setting pressure.
• As unload valve - pressurized oil is released to tank when external pilot pressure exceeds the pressure setting to unload the circuit.
