Overview of ZJHP single seat pneumatic control valve
ZJHP series of films through single seat pneumatic control valve driven by the top structure, equipped with multi spring actuator. Has the advantages of compact structure, light weight, flexible action, fluid channel was streamlined, advantages of the 3 small pressure drop loss, valve capacity, flow characteristics of precision, convenient assembly and disassembly etc.. Widely used for precise control of gases, liquids and other media, the process parameters such as pressure, flow, temperature, liquid level remains in the given value. In particular the workplace to allow leakage star small valve and pressure.
This series of products are the standard type, adjust the cut-off valve, bellows seal type, jacket type insulation and other varieties. Nominal grade products are PN10, 16, 40, 64; body diameter range of DN20~300. Application of fluid temperature from -196 ℃ ~+560 ℃ range of different grades. Leakage star standard with IV or VI. Flow characteristics such as linear or percentage. A variety of different specifications can be selected.

Characteristics of ZJHP single seat pneumatic control valve
1 Top oriented single seat control valve, compact structure, few components, Yi Weixiu.
The 2 metal spool for a variety of occasions, as IV level leakage standard, structure of soft seal spool up to VI level leakage standard.
3 valve according to the principle of fluid mechanics design into a uniform low resistance flow, rated flow coefficient of 30%. Big adjustable range, inherent adjustable ratio 50:1. Implementing agencies for the use of multi spring structure, height reduction of 30%. , weight 30%.
4.ZJHPW shaped bellows seal valve, the stem form of mobile complete sealing, blocking the fluid leakage. With an insulating jacket type ZJHPJ valve, used for fluid cooling crystallization, solidification clogging situation.
