Holding Valve Spool AV280 Excavator Hydraulic Parts Engineering Machinery Parts

Features:

1. Pressure maintenance function: Keep the valve spool according to the set pressure value, keep the pressure of a circuit in the hydraulic system stable. Once the pressure in the system drops below the set value, the holding valve spool opens automatically, allowing hydraulic oil flow into the circuit to maintain the set pressure.

2. High precision control: The retaining valve spool usually has a high control accuracy, and can achieve small pressure fluctuations within a certain pressure range. This is important for hydraulic systems that need to maintain constant pressure, such as jigs that need to maintain fixed point working pressure or working environments that require high stability.

3. Fast response: The response speed of the valve spool is usually very fast. Once the pressure in the system drops below the set point, the holding valve spool opens rapidly, allowing hydraulic oil flow into the circuit to replace the pressure loss. This fast response helps maintain system stability and reliability.

4. Adjustable: The retaining valve spool is usually adjustable, allowing the user to set the pressure according to the specific needs. By adjusting the regulating device on the spool or replacing the spool of different pressure ranges, the holding function of different pressure levels can be achieved.

5. Pressure resistance: the valve spool is usually able to withstand higher working pressure. They are designed and manufactured to ensure safe and stable operation in the system and have adequate pressure resistance.
