Filling Valve ZSFW200F0-1-2X/M/01D40 - Bosch Rexroth R901310564

Bringing a press from rapid stroke into the pressing stroke calls for a cross section at the cylinder head that no pipe run can deliver. This version of the ZSFW200 weighs 71 kg, carries up to 7000 l/min and seals up to 350 bar with NBR seals.

Benefits

• NBR seals for hydraulic fluid HL, the standard set for mineral oil in the usual temperature window.
• A mass of 71 kg instead of the heavier variant makes fitting and replacement at the cylinder head easier.
• Filling flow of up to 7000 l/min out of the tank, so the pump never has to supply that volume.
• Pilot-operated seat element that blocks the cylinder chamber up to 350 bar during the pressing stroke.
• Mechanical actuation, which removes solenoid, cable and plug from the installation.
• Size 200 in sandwich plate design with a connection pattern to ISO 228-1.

Technical data

Applications

This valve belongs on the upper ram of forming and plastics presses whose cylinder is filled from the tank without pressure during the rapid stroke. On the change to the pressing stroke the seat element closes and separates cylinder and tank. Compared with the FKM version this variant is matched to common mineral oils.
