Pilot-operated check valves

Precise control and safety for your hydraulic systems

In this category, we offer a wide selection of professional pilot-operated check valves, which form the foundation of safety and precise motion control in hydraulic systems. Our valves are designed to eliminate the cylinder creeping effect and protect installations against the consequences of a sudden pressure drop.

VBPSE VIE pilot-operated check valves

VBPSE 4 VIE type valves are high-quality hydraulically operated check valves (type "pilot-operated check valves"). Their main task is to block the fluid flow in both directions in the absence of a control signal and to allow free flow when pressure is applied to the control line.

Main applications:

• Locking actuators: They ensure a safe stop of the actuator piston in the desired position without the "creeping" effect, even with the pump turned off.

• Safety: They prevent the load from falling in the event of a hydraulic hose failure.

• Hydraulic systems: Used mainly in industrial and mobile applications where precise position control is required.

VBPSE A pilot-operated check valves with opposite ports

VBPSE A type valves are professional hydraulically operated check valves that stand out due to their specific design with opposite ports. They were designed to maximize the simplification of installation in hydraulic systems where compact design and aesthetic, functional routing of supply lines are priorities.

Main applications:

• Space optimization: Thanks to the opposite arrangement of the output ports, these valves are ideal for tight spaces where installing standard valves would be difficult or would require the use of additional elbows and adapters.

• Locking actuators: They ensure a firm and safe stop of the actuator piston in the desired position, effectively eliminating the "creeping" phenomenon caused by internal leakage.

• Operational safety: They perform a key safety function, immediately blocking the oil outflow from the actuator in the event of a hydraulic hose failure, which prevents uncontrolled load dropping.

• Mobile and industrial applications: They find wide use in construction, agricultural machinery, and lifting equipment, where the reliability of the lock under load is required to maintain the highest safety standards.

VBPSL pilot-operated check valves with metric ports

VBPSL type valves are specialized hydraulically operated check valves designed for installations requiring the use of metric standard connections. Thanks to the precise execution of the threads, these valves ensure perfect tightness and full compatibility with hydraulic systems based on metric standards, eliminating the need for additional reduction fittings.

Main applications:

• Compatibility with metric systems: They provide a dedicated solution for machines and devices in which the entire hydraulic system is based on the metric standard, ensuring fast and professional installation.

• Locking actuators: They effectively eliminate the actuator piston "creeping" effect, guaranteeing its stable stop in the selected position even under high load and with the pump turned off.

• Load safety: They protect against uncontrolled dropping of mechanisms or loads in the event of a sudden failure of hydraulic hoses, acting as a key safety feature for the system.

• Specialized applications: Ideal for modern agricultural, construction machines, and advanced industrial systems where high precision of connections consistent with the technical specification of the project is required.
