Features
Threaded locking Protection
Threaded locking can prevent mechanical wear and brinelling caused by steel ball locking.
Low Oil Leakage
The flat valve leaks very little during disconnecting and connecting, reducing the losses of oil in the hydraulic circuit.
Low Pressure Drop & High System Efficiency
The internal design of the valve and the use of high-strength materials help to achieve a minimum pressure drop and improve system efficiency.
High Pulse Resistance
It can be used in high-pressure and high-pulse frequency heavy-duty conditions.
