Proportional flow-control cartridge, series MVRPLSA

The two-stage proportional flow-control cartridge in this series guarantees outstanding load-holding function thanks to leak-free design and load-independent lowering.

The new principle makes it possible to combine several functions in one valve. On the one hand, the leak-free nature is preserved thanks to the ingenious seat design, which shuts off the main and control functions simultaneously and with zero leakage, allowing loads to be held in position for long periods. On the other hand, the integral pressure-compensator function enables responsive, controlled and load-independent lowering.

These unrivalled features are all-important for the economic and convenient handling of loads of all kinds.

Advantages

• Seat-valve shut off from 2 to 1
• Load-independent flow rate
• Multifunction cartridge with compact design
• Very good reproducibility
• More reliable operation over the whole pressure and flow range
