HY-Sperrventil SCA16CZ2X/JM - Bosch Rexroth R900394217

When a load pulls on the cylinder, it runs away without counter-holding and flow no longer follows the valve stroke. The SCA16CZ2X/JM is fitted as a sandwich plate beneath a proportional directional valve and turns it into a load-compensated flow controller for 130 l/min nominal flow.

Benefits

• Load-compensated control of pulling and pushing loads together with a proportional directional valve.
• 130 l/min nominal flow in size 16 at up to 315 bar operating pressure.
• Sandwich plate design to connection diagram ISO 4401-07-07-0-05, so no extra control block is required.
• Spool symbol A1 to A2, B1 to B2 across four ports.
• Spindle with hexagon for manual actuation and on-site adjustment.
• 7.08 kg weight with NBR seals and hydraulic fluid HL.

Applications

The assembly is used on lifting and lowering axes, tilting gear and feed drives where the load pulls in the direction of travel for part of the cycle. As a sandwich plate it goes between subplate and directional valve and needs no mounting face of its own.
