Manapak Sandwich Valves

CM Series Check Valves

The Series CM Manapak check valves provide an integral, full flow check valve in the pressure 'P' port, 'A' port, 'B' port, or the tank 'T' port of the directional valve. Reverse flow is blocked. The CM2 and CM3 sizes offer a combination P&T check version.

• Valve bodies are manufactured from steel which provides extra strength and durability for longer life. Internal hardened steel components also provide longer life.
• Positive shut-off is provided by a fully guided poppet and allows full flow in the unchecked position.
• Parker Manapak CM sandwich style check valves can be used either on the 'P', 'A', 'B', 'T' ports, or combinations.
• Large internal flow paths allow high flow at low pressure drop.

CPOM Double Pilot Operated Check Valves

The CPOM series of double pilot operated check valves blocks leakage from the actuator ports to tank when the directional valve is in the center position.

• Parker Manapak CPOM sandwich style, p.o. check valves can be provided in either single or double configurations
• The p.o. checks may be positioned in 'A' port or 'B' port; or both 'A' and 'B' ports.
• Valve bodies are manufactured from steel providing extra strength and durability for longer life. Internal hardened steel components also provide longer life.
• Positive shut-off is provided by a hardened poppet and cage assembly.
• Large internal flow paths allow high flow at low pressure drop.

FM Double Flow Control Valves

The Series CM Manapak check valves provide an integral, full flow check valve in the pressure 'P' port, 'A' port, 'B' port, or the tank 'T' port of the directional valve. Reverse flow is blocked. The CM2 and CM3 sizes offer a combination P&T check version.

• Valve bodies are manufactured from steel which provides extra strength and durability for longer life. Internal hardened steel components also provide longer life.
• Positive shut-off is provided by a fully guided poppet and allows full flow in the unchecked position.
• Parker Manapak CM sandwich style check valves can be used either on the 'P', 'A', 'B', 'T' ports, or combinations.
• Large internal flow paths allow high flow at low pressure drop.

PRDM Direct Operated Pressure Reducing Valves

Series PRDM are direct operated pressure reducing valves that are used to regulate pressure in one area of a hydraulic circuit at a predetermined level below normal system pressure. Additionally, an integral pressure relieving function for the secondary reduced pressure circuit is incorporated into the design.

• PRDM Manapak sandwich valves may be selected to reduce pressure in the 'P' port, 'A' port or 'B' port.
• The direct operated, cushioned piston design results in fast response, low leakage and minimal hysteresis.
• Up to four pressure adjustment ranges are available with maximum pressure settings of 25, 64, 160 and 210 Bar (363, 928, 2320, 3045 PSI).
• Options include: A choice of two adjustment styles, three seal materials and four gage port sizes.

PRM Series Reducing Valves

PRM Series reducing valves are used to regulate pressure, in one area of a circuit, below normal system pressure. The Manapak style valve is well suited to perform this function as it mounts directly below the directional control valve.

Operation

These are "normally open" valves that allow fluid to pass through the controlled port during typical operation. When downstream pressure rises above the value set by an adjustable spring force, the control pilot opens and allows the main spool to move from a full open position. The main spool modulates to maintain the desired "reduced pressure" downstream of the valve.

Features

• Parker Manapak PRM sandwich style pressure reduc-ing valves can be used to reduce pressure on the 'P' port, the 'A' port, or the 'B' port.
• Three pressure adjustment options are available: slotted screw, knob and locking knob.
• Valve bodies are manufactured from steel which provide extra strength and durability for longer life. Internal hardened steel components also provide longer life.

RM Series Relief Valves

RM Series relief valves limit system pressure by opening to tank when system pressure reaches the valve setting. With D03 size, they can also be configured to limit the 'A' or 'B' work port pressures independently.

• Parker Manapak RM sandwich style relief valves can be used to limit pressure in the 'P' port, 'A' port, or 'B' port.
• Valve bodies are manufactured from steel which provide extra strength and durability for longer life. Internal hardened steel components also provide longer life.
• Three pressure adjustment options are available: slotted screw, knob and locking knob.
