Festo 5/3 Pressurised Valve

The Festo VSVA-B-P53U-A2-P1 is a 18 mm piston gate valve with a 5/3 pressurised function and overlap lap. It delivers a standard nominal flow rate of 450 l/min at operating pressures from 3 bar to 10 bar. Electrical actuation and a mechanical spring reset suit automated pneumatic circuits. The soft sealing principle and any mounting position simplify installation.

Replaces 5/2 or 3/2 Valves

Upgrade when a centre pressurised position is required to hold actuator pressure during power loss. The overlap lap prevents cross-talk between ports, which a standard 5/2 valve cannot guarantee. The jump is worth it for safety-critical clamping or holding circuits that need maintained pressure without continuous coil energisation. The 98 g weight keeps moving mass low.

Fits 18 mm Manifold Systems

The valve mounts on any 18 mm manifold pattern with a tightening torque of 0.9 Nm to 1.1 Nm. Pilot medium must be compressed air to ISO 8573-1:2010 [7:4:4] for reliable sealing. Exhaust flow control option allows local speed tuning without extra fittings. Operating temperature range of -5 °C to 50 °C matches standard factory environments. Not for buyers who need a 5/2 function only or a larger nominal width than 5 mm.
