Product Features
◉ O-type Neutral Spool Function When the control lever is in neutral, the pressure inlet port (P) and return port (T) are cut off, while service ports A and B are fully sealed. This locks hydraulic cylinders and motors firmly in position without drifting.
◉ T-type Spring Centering Reset Mechanism After releasing the operating handle, the valve spool automatically springs back to the neutral position via built-in return springs for stable operation.
◉ Integrated Direct-Acting Relief Valve Equipped with a built-in relief valve to cap the maximum system working pressure and protect hydraulic equipment from overload damage.
◉ Series & Parallel Combined Hydraulic Circuit Design Adopts parallel loop layout across multiple spools, enabling simultaneous combined operation of multiple hydraulic actuators.
