4-Way Solenoid Valves sourcingAbout 4-Way Solenoid Valves
5/2 and 4/2 solenoid valves for double-acting cylinders and actuators, single and double solenoid, inline, manifold, NAMUR and ISO 5599 mounting.
A 4-way solenoid valve alternately pressurises one side of a double-acting cylinder or pneumatic actuator while exhausting the other, which is what strokes the piston in both directions. Modern pneumatic practice builds them as 5/2 valves, with one pressure port, two outlets and two exhausts; the 4/2 designation with a single shared exhaust survives mainly in hydraulics and some compact designs, and both do the same job. Single-solenoid valves return by spring to a defined position on power loss, while double-solenoid (bistable) valves hold their last position, a fundamental fail-mode decision. 5/3 variants add a centre position, closed, exhausted or pressurised, for mid-stroke stopping. Indian manufacturers commonly supply aluminium and stainless bodies from 1/8 to 1/2 inch inline, manifold-mounted banks, NAMUR-pattern valves for quarter-turn actuators, and sub-base valves to the ISO 5599 interface, with IP65 coils and Ex d or Ex m hazardous-area options. State in your enquiry the valve function and mounting, port size or Kv, single or double solenoid, medium and pressure, coil voltage, enclosure or certification, and quantity.
