Product Introduction
ZJHPPneumatic thin film single seat regulating valveZJHP Pneumatic Control Valve ZJHP Explosion proof Pneumatic Stainless Steel Control Valve/Pneumatic Control Valve with Signal Feedback/Pneumatic Thin Film Control Valve ZJHP-16C Pneumatic Control Valve ZJHP-16P Pneumatic Stainless Steel 304 Control Valve ZJHP-16RL Explosion proof Pneumatic Stainless Steel 316L Control Valve ZJHP Pneumatic Steam Control Type/Pneumatic Pressure Control Valve/Pneumatic Flow Control Valve ZJHP Pneumatic Carbon Steel Control Valve ZJHP Pneumatic Cast Steel Control Valve/Pneumatic Single Seat Control Valve/Precision Pneumatic Thin Film Control Valve/ZJHP-16P Pneumatic Thin Film Stainless Steel Control ValveIt is composed of a multi spring pneumatic diaphragm actuator and a low flow resistance precision small regulating valve body. The multi spring actuator has low height, light weight, and easy equipment. The flow channel of the pneumatic control valve body is S-shaped, which has the advantages of compact structure, light weight, sensitive action, low pressure drop loss, large valve capacity, precise flow characteristics, and easy maintenance. It can be used in harsh working conditions. Pneumatic control valves equipped with electrical valve positioning or pneumatic valve positioners can achieve automatic regulation and control of fluid media in process pipelines. Pneumatic control valves are widely used to precisely control process parameters such as pressure, flow rate, temperature, liquid level, etc. of gases, liquids, steam, and other media to maintain them at given values. Especially suitable for situations where leakage is allowed to be small, the pressure difference before and after the valve is not large, and there is a certain viscosity and a small amount of fiber medium.
Single seat regulating valve, compact structure, few components, easy to maintain.
Key Features:
1. Top guided single seat regulating valve, compact structure, few components, easy to maintain.
2. The metal valve core is suitable for various working environments and meets the IV level leakage standard, while the soft seal structure valve core meets the VI level leakage standard.
3. The valve body is designed according to the principles of fluid mechanics as a low resistance flow channel with equal cross-section, increasing the rated flow coefficient by 30%. The adjustable range is large, with an inherent adjustable ratio of 50:1. The actuator adopts a multi spring structure, reducing height by 30% and weight by 30%.
4. The ZJHPW type bellows sealed regulating valve forms a good seal for the moving valve stem, preventing fluid leakage.
5. The ZJHPJ type regulating valve is equipped with an insulation jacket, which is used in situations where the fluid is prone to crystallization and solidification after cooling, causing blockage.

Form of action:
1. Gas closed type (B) - valve position open when gas is lost (FO).
2. Pneumatic (K) - Valve position closed (FC) when gas is lost.
3. The gas shut-off valve consists of a positive acting actuator and a regulating valve body. When the input signal pressure changes from the lower limit value to the upper limit value, the valve opens from fully open to fully closed.
4. The pneumatic valve consists of a reaction actuator and a regulating valve body. When the input signal pressure changes from the lower limit value to the upper limit value, the valve moves from fully closed to fully open.
