PARKERParker pressure reducing valveD1VW004CNJWThe automation basic component used to control the direction of fluid belongs to actuators; Usually used in mechanical control and industrial valves to control the direction of the medium, thereby achieving control of valve opening and closing. The solenoid valve has a sealed chamber with through holes at different positions, each leading to a different oil pipe. The middle of the chamber is the valve, and there are two electromagnets on both sides. The magnetic coil on either side will attract the valve body to the other side. By controlling the movement of the valve body, different oil discharge holes can be blocked or leaked out. The oil inlet hole is normally open, and hydraulic oil will enter different oil discharge pipes. Then, the pressure of the oil will push the piston of the cylinder, which in turn drives the piston rod, and the piston rod drives the mechanical device to move. In this way, the mechanical motion is controlled by controlling the current of the electromagnet. Only solenoid valves use electromagnetic force to seal the iron core inside the magnetic sleeve of the electric control valve, without dynamic sealing, so external leakage is prone to blockage.

PARKERWhen the outlet pressure P2 of the pressure reducing valve is at the set value. Parker pressure reducing valve cone valve is closed, the oil pressure in the upper and lower chambers of the main valve core is equal, and spring 10 keeps the main valve core at the lower end The valve is fully open and does not have a pressure reducing effect. When the outlet pressure of the Parker pressure reducing valve rises above the pressure set by the pressure regulating spring 11 The cone valve is open. The oil from the Parker pressure reducing valve flows back to the oil tank through the pilot valve and the oil leakage day. The Parker pressure reducing valve experiences a pressure drop due to the damping hole. When the pressure difference force between the upper and lower chambers of the main valve core is greater than the preload force of spring 10, the main valve core 7 rises, reducing the gap between the pressure reducing port and increasing the liquid resistance Resulting in a decrease in export pressure P2. On the contrary, it will lead to a rebound in exports.

PARKERParker's proportional pressure reducing valve can provide electronically controlled pressure reduction to protect system components and assist in force and torque control. The pressure relief valve adopts a slide valve design, with an inlet, a pressure reducing oil port, and a return oil port. When a high pressure is provided at the inlet, changing the current of the electromagnetic coil can output a proportional pressure reduction pressure lower than the inlet pressure at the pressure reducing oil port. When there is no current input, the pressure reducing oil port is unloaded to the oil tank, while the inlet port is closed by the valve core. Once there is a signal current input, the valve core undergoes displacement, the valve port opens, and the liquid flow from the inlet to the pressure reducing oil port is throttled to maintain a constant pressure at the pressure reducing oil port. The larger the input current, the higher the pressure reducing pressure. If the depressurization pressure is too high and exceeds the input command pressure, the pressure at the depressurization port will overflow to the fuel tank. Electromagnetic coils have two options, AC and DC, and a large number of electrical connection interfaces to choose from. Due to changes in coil temperature, it is preferable to use current controlled pulse width modulation (PWM) valves and amplifier drivers for regulation. In addition, such amplifiers also have the ability to provide vibration signals at a certain frequency.
