Pilot-operated Hydraulic Check Valve VBCD-G1-2 SE-G Hydraulic Valve With G1 Port 

Product Introduction

The VBCD-G1-2 SE-G is a pilot-operated hydraulic check valve designed for high-pressure applications. Constructed from durable materials, it features a standard G1 port size and a screw-in cartridge design for easy installation into hydraulic manifolds. Its poppet-style mechanism ensures reliable, leak-free blocking of reverse flow in one direction while allowing free flow in the forward direction. The valve opens with an external pilot pressure signal ("SE"), enabling controlled release of the held load. Key attributes include robust pressure handling, fast response times, and excellent resistance to contamination. It is commonly used in integrated hydraulic systems where compact, reliable, and maintenance-friendly components are essential for safety and performance.

Product Summary

Hydraulic valves are classified based on their core functions. The primary categories include:

Directional Control Valves (DCVs): These manage the start, stop, and direction of fluid flow. They are subdivided into check valves (allowing flow one way), and multi-port valves (like 4/3 valves) that direct fluid to different actuator ports.

Pressure Control Valves (PCVs): These regulate system force by managing pressure. Key types are relief valves (for safety limiting), reducing valves (for lowering branch pressure), and sequence valves (for operating actuators in a set order).

Flow Control Valves (FCVs): These govern actuator speed by precisely metering the flow rate, either with fixed or variable orifices. This category includes throttle valves, flow dividers, and pressure-compensated models for consistent speed under varying loads.

The choice of valve type is fundamental to achieving the desired power, precision, and safety in any hydraulic circuit.

Product Application

The VBCD-G1-2 SE-G is primarily used for secure load-holding and motion control in industrial and mobile hydraulic equipment. Its main application is to lock hydraulic cylinders in position, preventing unintended movement in machinery such as presses, clamping devices, lifting platforms, and material handling equipment. It is also critical in circuits for winches, cranes, and excavator booms to safely hold loads even when system pressure drops. Furthermore, its design makes it suitable for use in custom hydraulic power units and manifold blocks within automation systems, plastic injection molding machines, and heavy-duty construction machinery, ensuring operational safety, stability, and precise control.
