Common questions on this part

The valve includes a reversible interface plate between the valve body and actuator face. By loosening the two securing screws and rotating the plate 180 degrees, the internal porting aligns for either 3/2-way operation (for spring-return single-acting actuators) or 5/2-way operation (for double-acting actuators).

Standard replacement coils are available in 220V/230V AC (50/60 Hz), 110V AC, and 24V DC. Coils feature an IP65 DIN 43650 Form A socket and can be interchanged on the stem without venting pipeline air pressure.

The 4M-OTX-PPT operates reliably on standard industrial plant compressed air filtered to 50 microns. While dry, filtered air is recommended for maximum seal longevity, the poppet seat geometry is significantly more tolerant of line dust and moisture than spool-type valves.

STARNEX supplies 4MATIC valves on order with standard factory dispatch. Technical datasheets, installation dimensions, and official KRA E-TIMS tax invoices are provided with all commercial orders.
