Product description:

ZX new series of pneumatic film three-way valve with cylindrical thin-walled window-shaped spool-oriented, different from the plunger spool guide. Equipped with multi-spring actuator. Has the advantages of simple structure, light weight, small size, easy disassembly. Widely used in precise control of gas, liquid and other media, process parameters such as pressure, flow, temperature, liquid level at a given value. Suitable for a fluid through the three-way valve is divided into two out or the two fluids through the three-way valve into a fluid situation. 

This series of products have three links and three links diversion two. Nominal pressure of 1.6,4.0,6.4 MPa; body diameter range DN25 ~ 200. Applicable fluid temperature from -60 ℃ ~ +450 ℃. Leakage standard Ⅳ level. Flow characteristics of a straight line, two kinds of parabola.
 

Features:

 1, the direction of fluid on the role of the valve are in a state of flow, so the valve can work stably. 
 2, in addition to the bonnet at the bushing orientation, the valve core side and the inner surface of the valve seat also has a guiding role in guiding a large area, reliable work. 
 3, the implementing agencies using multi-spring structure, a 30% reduction in height, weight reduction of 30%.
