DESCRIPTION
Parker派克MVI系列截止与节流阀

Unidirectional valve CM series

Description: The Parker Manapak CM series check valve is a stacked component used for stacked connection with directional valves with standardized connection holes. Depending on the function, one or two one-way valves can be configured in the corresponding channels P, T, A, and B of the Manapak overlay valve. The quantity and direction of action are specified by code letters.
characteristic
The Parker Manapak CM series valve has a steel valve body.
The eight available configurations of one-way valves in the valve body provide more usability for the hydraulic circuit.
If you want to change direction, you can exchange the positioning pin and rotate the valve body to achieve it.

Ppilot-operated check valveCPOMseries

Description: The Parker Manapak CPOM series hydraulic control check valve is a stacked component used for stacked connection with directional valves with standardized connection holes. Depending on the function, one or two hydraulic control check valves can be configured in channels A and/or B of the Manapak overlay valve. The direction of free flow is from the surface of the connecting valve to the surface of the connecting base plate

Pone-way throttle valveFMseries

Description: The Parker Manapak FM series one-way throttle valve is a stacked component used for stacked connection with directional valves with standardized connection holes. There are throttle valves and one-way valves configured in two channels A and B. By changing the installation position (FM2 and FM3) or internal components (FM4), the inlet or outlet throttling function can be achieved. In addition, throttle valves can also be used to control the switching time of pilot operated directional valves. In this usage scenario, this valve can be installed between the pilot stage (NG06) and the main stage (NG10 to 32).
FM6 can only be used for export throttling.

PDirect acting pressure reducing valvePRDMseries

Description: The PRDM series components are direct acting pressure reducing valves. Mainly used to regulate the pressure of a certain branch in the hydraulic system to a predetermined value below the system nominal pressure.
In addition, the overflow function of this branch is also integrated.
The pressure gauge interface or measuring interface is directly on the component to control the branch pressure.
function
This valve is a normally open component that allows oil to flow freely through the control channel below the set value. When the pressure in the downstream channel rises to the pre regulated pressure, the valve core moves in the direction of closure to reduce the flow from the main system, and the buffer plunger will adjust itself to maintain the predetermined branch system pressure. When the pressure in the branch system increases due to external forces, the buffer plunger will overcome the spring force and move, causing a large amount of oil to flow back to the tank, preventing the pressure from continuing to rise.
The leaked oil flows back to the oil tank through the spring chamber.

PDirect relief valveRDMseries

Description: The RDM series relief valve is a direct acting plunger structure with low hysteresis. Can be used as an RT overflow and T-T back pressure control valve. There are four maximum pressure adjustment ranges to choose from: 25, 64, 160, and 210 bar.
The valve body is equipped with a pressure gauge
Test the connection port.
function
The PT structure is normally closed at the initial position and allows oil to flow freely through the P channel. When the pressure in the channel exceeds the set value, the valve core overcomes the spring force and moves, causing a large amount of oil to flow back to the tank, preventing the pressure from continuing to rise.
The leaked oil flows back to the oil tank through the spring chamber.
The TT structure can generate a pre pressure in the T channel according to the set value, acting as a back pressure.

PPilot-operated reducing valvesPRMseries

Description: The Parker Manapak PRM series pilot operated pressure reducing valve is a stacked component used for stacked connection with directional valves with standardized connection holes. Pressure reducing valves, except for PRM3AA and BB models, are always configured in the P-channel.
The pressure reduction of the desired oil port is achieved through internal control and the connection between the leakage pipeline and the corresponding flow channel.

PPilot operated relief valveRMseries

Description: The Parker Manapak RM series pilot operated relief valve is a stacked component used for stacked connection with directional valves with standardized connection holes. Depending on the functional purpose, for some valves, P can be selected A、 Or B port is used as pressure control, but T always unloads the oil to the tank.
