Пружина клапана управления Caterpillar 8J4481

The Pilot Control Valve Spring provides the force necessary to keep the pilot valve spool in the closed or neutral position when there is no pilot pressure applied. This ensures the main valve remains closed until the pilot valve is actuated. Maintain the position of the pilot control valve spool when the engine is not running and there is no pilot pressure available. Without the spring, the spool could drift from its neutral position. Attributes:• Manufactured to precise specifications and are built for durability and reliability• Makes the pilot valve more responsive, but may require higher pilot pressure to actuateApplications:The Pilot Control Valve Spring force, combined with the pilot pressure, determines the opening pressure of the pilot valve. This allows the pilot valve to regulate the pressure supplied to the main valve, ensuring proper actuation.
