Special Valves
Pre-filling valves
Pre-filling valves are hydraulically piloted and directly mounted on the press cylinder; they offer the ideal condition to reduce to the minimum pressure drops and are specifically designed to fit customer cylinders in press applications.
General features
- Full bore valve
- Adjustable switching speed of actuator
- Independent opening of the poppet valve from the piloting piston
- Spool NC position guaranteed by the spring
- Metal to metal seal
- Hydraulic shock absorber system between the piloting piston and the poppet valve
- Equipped with two proximity switches
Technical data

- Ambient temperature +2°C ÷ +60°C
- Connections UNI
- Materials Body in carbon steel
Anti-fall valves
Automatic anti-fall system to isolate the cylinder supports of the press crossbeam in case of press maintenance or serious accidental falls of press feeding pipes.
