Special Valves

Product catalog summary

General Features
Pre-filling valves are designed for hydraulic piloting and direct mounting on press cylinders, minimizing pressure drops. They are tailored for customer-specific cylinder applications in forging and extrusion presses. Key features include a full bore valve, adjustable actuator switching speed, independent poppet valve opening, a spring-guaranteed spool NC position, metal-to-metal seal, hydraulic shock absorber system, and two proximity switches.

Technical Data
The valves are compatible with water and HFA fluids, supporting working pressures up to 350 bar (35 MPa) and ambient temperatures ranging from +2°C to +60°C. They feature UNI connections and a carbon steel body.

Accessories
Available accessories include an interface for existing cylinders and a flow regulator.

Valve Sizes
Valve sizes are specified as follows: DN 200 (8 inches), DN 250 (10 inches), and DN 300 (12 inches). Dimensions for each size are provided, with options for special flanges.

Options
Special flanges are available as an option. Note that specifications and dimensions are subject to change due to ongoing research and development.
