Prefill valves SVF
As Check valves for free flow in one direction and blocked flow in the opposite direction. As Pre-Fill valves in the press controllers for further-suction and emptying the press cylinders when closing and opening in rapid traverse. Zero leakage in the blocked direction.
Pre-Fill valves are available without and optionally with hydraulic pre-relief. In the case of the standard version without pre-relief, decomperssion takes place via a directional control valve with an up-stream orifice or throttle until there is complete decompression in the cylinder. Decopression takes place automatically in valves with.
