3/2-way air operated valve, normally open, spring return, G 1/4, 980 l/min - YPC SFP4701

Where a line should normally be pressurised and only be shut off on a signal, the YPC SFP4701 fits. When pilot pressure is applied at the G 1/8 port, this NO valve closes the supply and vents the working port. With G 1/4 ports it passes 980 l/min.

Advantages

• Open rest position: the line stays pressurised as long as no pilot signal is applied.
• Oil-free operation: no lubrication required, if lubricated use ISO VG32 oil.
• Body and spool in aluminium, NBR seals, pilot section in glass fibre reinforced polyamide.
• Purely pneumatic actuation with 2 to 8 bar pilot pressure, no electrical energy is needed at the valve.

Applications

• Medium bore cylinders in fixtures and feeders with G 1/4 lines.
• Single-acting cylinders that should stay extended without a pilot signal.
• Supply lines that carry pressure in normal operation and are shut off on a signal.
