SUN FDCB-HAN Hydraulic Cartridge Valve
Product Overview
SUN FDCB-HAN is a pressure-compensated adjustable flow Hydraulic valve with built-in reverse check function. As a precision Hydraulic valve, it is installed inside the manifold block to regulate oil flow in the hydraulic system of industrial and mobile Machine. This cartridge type Hydraulic valve can maintain stable flow output even with fluctuating working pressure. It supports infinitely variable flow adjustment from nearly fully closed to maximum flow, and the integrated check valve allows free reverse oil return. It is a key control component for precise speed control of cylinders and actuators in the hydraulic system.

Working Principle
When the Machine is running, pressurized hydraulic fluid flows through this Hydraulic valve. The built-in pressure compensator automatically offsets load pressure variation to keep the set flow constant. Users can manually adjust the orifice size to control the movement speed of hydraulic actuators. For reverse return flow, the integrated check valve opens and allows unobstructed oil flow back to the hydraulic system. The compact cartridge structure realizes flow regulation without bulky valve body, simplifying the manifold layout of the Machine.
Core Advantages
1. Pressure compensation design ensures stable flow, reduces speed fluctuation of the Machine under variable load in the hydraulic system.
2. Infinite adjustable flow range, convenient on-site tuning for the Hydraulic valve.
3. Integrated reverse check valve, simplifies piping of the hydraulic system, saves installation space.
4. Sharp-edged orifice design minimizes flow change caused by oil viscosity variation.
5. Standard T-5A cavity, easy installation and replacement of the threaded cartridge Hydraulic valve.
Application Range
This SUN Hydraulic valve is widely used in construction Machine, material handling equipment, machine tools and automated production lines. It is used for meter-in / meter-out speed regulation of the hydraulic system, controlling the movement speed of hydraulic cylinders in clamping, lifting and feeding actions.
