ZMAQ/XThe pneumatic and pneumatic membrane three way confluence and split flow control valve is guided by cylindrical thin wall window shaped valve core, which is different from the bushing guide of the plunger type valve core. Equipped with multi spring actuator, it has the advantages of simple structure, light weight, small size and convenient disassembly and assembly. Widely used for accurate control of gas and liquid at a given value. The utility model is suitable for the flow of a fluid through a three-way valve, which is divided into two ways to flow out or to merge two kinds of fluids through a three-way valve into a fluid.
This product has three connections and three bypass two kinds. Nominal pressurePN164064Nominal diameter rangeDN25-300. Applicable fluid temperature-60to+450. Leakage standardClass. There are two kinds of flow characteristics: straight line and parabola.
