Hydraulic valve selection

•Selection of hydraulic valve rated pressure:

•Determine the hydraulic valve according to the working pressure of the system so that the system working pressure is lower than the rated pressure of the product.

•Hydraulic valve flow parameter selection:

•Determine the rated flow rate of the valve based on the maximum flow rate under the working condition of the hydraulic system.

•Hydraulic valve installation method selection:

•Threaded connection, plate connection, flange connection, depending on the structure and layout characteristics of the system.

•Selection of hydraulic valve control method:

•Depends on the operating needs of the system and the configuration capabilities of the electrical system.

•Selection of hydraulic valve structural form:

•For systems requiring fast commutation speed, choose AC electromagnets

Directional valve, on the contrary, choose the direction of DC type solenoid

valve.
