Parker hydraulic valve E2B040ZNMK3 originally imported E2B040

Parker pilot proportional directional valves are used to control flow. The valve has integrated electronics and an adjustable spool position for the main stage. Typical applications are: flow control Accurate and achievable flow regulation, operation in fast/low speed characteristics with spool position monitoring for: press control, dynamic position regulation and pressure/flow closed-loop systems. Technical features: small leakage, high frequency sound, large oil flow capacity, accurate fault diagnosis, mechanical zero adjustment of zero cover valve, high strength, displacement feedback of spool position, optional spool position travel monitoring.

PARKER proportional valve is a new type of hydraulic control device. In the ordinary pressure valve, flow valve and direction valve, the proportional electromagnet is used to replace the original control part, and the pressure, flow or direction of the oil flow is controlled remotely according to the input electrical signal continuously and proportionally. Proportional valves generally have pressure compensation performance, and the output pressure and flow rate can be unaffected by load changes.

The classification according to PARKER proportional valve control mode refers to the classification according to the electric-mechanical conversion mode in the pilot control valve of the proportional valve, and the electrical control part has a variety of forms such as proportional electromagnet, torque motor, DC servo motor, etc.
