Prefil Valve PV32-80
Prefill and Exhaust valves model PV** are seat type check valves, allowing free flow from its port A to port B and leak-free closure in opposite direction. For reverse flow, these valves can be opened by applying pilot pressure to its port X.
Product Description
The valves are designed for the purpose of pre-filling large cylinders during their rapid approach motions, which are actuated mean like a pair of kicker cylinders or jack up cylinders or by gravitational force.
These valves have very low cracking pressure and generous internal passage to help them to offer least possible pressure drop while pre-filling. Due to low pressure drop, these valves also can handle much higher exhaust flow enabling rapid return of the cylinders. For connectivity, it’s A port is machined as per Port dimensions for Flanged connection ISO 6162.The special cavity for the B port helps the user to mount these valves directly on the cylinders, thus further reducing the pressure drop in the line.
A hydraulic system having Prefill valve without decompression feature, must have an external arrangement of decompressing the oil in the cylinder, before the valve is opened.
