UNOX 3 Way Pneumatic Proportional Control Valve – 33611
The UNOX 3 way pneumatic proportional control valve is engineered for precise distribution and mixing of steam, water, and process fluids. With a robust GGG40.3 ductile iron body and PN25 pressure rating, it ensures reliable operation under demanding industrial conditions.
The actuator with multi-spring diaphragm design delivers accurate proportional control, while the valve can be configured for diverting or mixing functions. Equipped with PTFE soft sealing (Class VI) and V-pack stem sealing, it guarantees tight shut-off and long service life.
