Pneumatic three-way regulating principle of pneumatic valve

pneumatic three-way regulating valve, is made up of many spring type pneumatic diaphragm actuators and adopt cylinder thin wall window shape of the pneumatic valve core tee junction ( Shunt) Pneumatic valve. Has a simple structure, light weight, action quick, precise flow characteristic, with electricity - Gas pneumatic valve positioning or pneumatic pneumatic valve positioner, which can realize the process of the pipeline automatic adjustment control, are widely used in the precise control of gas, liquid and steam medium parameters such as pressure, flow, parameters such as temperature, liquid level in a given value. Suitable for the a fluid through the three links of pneumatic valve is divided into two flows or to combine two kinds of fluid through the tee pneumatic valve into a fluid condition. ZJHF, ZJHH pneumatic film the 3-way regulating pneumatic valve adopts pneumatic valve core guide cylinder type thin wall window form, different from the plunger type pneumatic valve core guide bushing. With spring actuator, has simple structure, light weight, small volume, convenient tear open outfit. Widely used in the precise control of gas, liquid and other medium technology in such as pressure, flow rate, temperature and liquid level in a given value. Suitable for the a fluid through the three links of pneumatic valve is divided into two flows or manage to combine two kinds of fluid through the tee pneumatic valve into the occasion of a fluid. This series of products have a three-way merge and three-way split two kinds. Nominal pressure PN,,,; Nominal diameter range DN - 。 Apply fluid temperature by - ℃ to + ℃. The standard for the leakage Ⅳ level. Flow characteristic has two kinds of straight line, parabolic.
