Prefill Valves
Intended for prefilling and exhausting of large hydraulic cylinders.
Can be used as anticavitation check valves.
Decompression feature is optional up to size 80.
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.
Features / specifications
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 valve also can handle much higher exhaust flow enabling rapid return of the cylinders.
