5/2-way pneumatic valve, double air pilot, impulse function, G 1/4, 800 l/min - E.MC
5/2-way pneumatic valve with G 1/4 ports and 800 l/min flow, switched by a pressure signal at the 2x G 1/8 pilot port. As an impulse valve it holds the last switched position even after the signal is removed. Operating pressure 1.5 to 8 bar, pilot pressure 2 to 8 bar.

Description
Where no voltage should be present at the valve, this air-actuated 5/2-way pneumatic valve does the switching: a pressure signal at the 2x G 1/8 pilot port shifts it. With a nominal size of 4.5 mm and 800 l/min at G 1/4 it feeds a mid-size cylinder directly.
Advantages
- Impulse function: a short switching pulse is enough, and the position is held if the signal drops out.
- 800 l/min with a nominal size of 4.5 mm, 3x G 1/4 ports and 2x G 1/8 exhaust.
- No coil at the valve: 2x G 1/8 pilot port, pilot pressure 2 to 8 bar.
- Aluminium alloy body and spool, NBR seals, service life of at least 40 million cycles.
Applications
- Double-acting cylinders on clamping fixtures that must hold position if the signal fails.
- Step sequences where a short pulse reverses the direction of motion.
- Rotary actuators and linear axes needing up to 800 l/min.
- Fully pneumatic control chains with signal transmitters such as roller lever or push-button valves.
