Pilot Operated Check Valve
Hydraulic valves designed to allow free flow in one direction while blocking the reverse flow of fluid until pilot pressure is applied
The pilot operated check valve is designed to allow free hydraulic fluid flow in one direction while blocking reverse flow to securely hold or lock the actuator’s position. When the pilot pressure is applied, the valve opens to permit reverse fluid flow, enabling controlled actuator movement. This design ensures reliable load holding and precise control in various hydraulic systems, improving operational safety and efficiency in mobile and industrial machinery applications.

Where Our Hydraulic Valves Work
Our hydraulic system valves and components are widely used in off-highway machinery, including construction equipment, agricultural machinery, and material handling equipment. Our hydraulic valves are also applied across various industries such as aerial work platforms, sanitation vehicles, and port machinery.
Our Partners
We want to ensure that the hydraulic cylinders on our material handling vehicles remain stable during operation. Can your hydraulic lock achieve this?
We want to ensure that the hydraulic cylinders on our material handling vehicles remain stable during operation. Can your hydraulic lock achieve this?
Yes, our pilot operated check valve features a modular and compact design that delivers safe and reliable load holding. It can be applied to various vehicle types and equipment to maintain actuator position and prevent unintended cylinder movement.
In excavator manufacturing, we need to prevent unexpected attachment movement during operation. Can your valve provide this level of safety?
In excavator manufacturing, we need to prevent unexpected attachment movement during operation. Can your valve provide this level of safety?
Absolutely. The hydraulic lock valve is an essential safety component for maintaining equipment stability that can be installed on excavator dozer blades, attachments, and other critical sections to lock cylinder positions and hold movement securely, preventing unintended shifts during operation.
Many earthmoving machines in road construction require hydraulic locks. Can your pilot operated check valve support different installation requirements?
Many earthmoving machines in road construction require hydraulic locks. Can your pilot operated check valve support different installation requirements?
Yes, our pilot operated check valve is available in multiple models and various specifications to meet different installation needs. It effectively prevents hydraulic actuators from moving unintentionally due to external forces or pressure loss, ensuring operational safety and stability across different machinery applications.
