Proportional Directional Valve 4WRGE16V125L-1X/315G24ETK31/A1M - Bosch Rexroth R900954154

A cylinder axis has to start from standstill, follow a ramp and stop on position. The 4WRGE16V125L-1X/315G24ETK31/A1M does that at 125 l/min nominal flow and 350 bar, because the on-board electronics track spool position with an internal transducer and correct any deviation from the command value immediately.

Benefits

• 125 l/min nominal flow, with the size 16 body rated up to 460 l/min, leaving headroom for rapid traverse
• Internal spool position feedback keeps the set opening stable even when load pressure changes up to 350 bar
• Command value ±10 V straight from a PLC analog card, no separate amplifier card in the cabinet
• Pilot oil supply and return routed internally, X and Y piping is not needed
• Mounting pattern ISO 4401-07-07-0-05, so the valve fits any standard size 16 subplate
• Mass 9.5 kg with NBR seals for HL mineral oil

Applications

Typical duty is presses, injection moulding machines and test rigs where a cylinder follows a force or position ramp. The 125 l/min rating suits medium sized cylinders in continuous operation. Since no external pilot circuit is required, the valve can also sit on compact manifolds that have no X and Y drillings.
