Wenzhou valve sleeve film regulating valve ZJHP DN65 precision small regulating valve

Description :

　　1. Product Overview

　　The ZJHP type pneumatic single seat regulating valve is composed of a ZHA/B type multi spring pneumatic diaphragm actuator and a top guided through low flow resistance single seat valve It has a compact structure, light weight, sensitive action, S-shaped fluid channel, small pressure drop loss, large valve capacity, flow characteristics, and can be equipped with electric pneumatic valve positioning or pneumatic valves to achieve automatic adjustment and control of process pipeline fluid media. It is widely used to control process parameters such as pressure, flow rate, temperature, liquid level, etc. of gas, liquid, steam and other media to maintain them at given values It is a new generation of universal regulating valve products that comply with IEC standards

　　structural characteristics

　　1. ZJHP pneumatic control valve is the execution unit of instruments in automation control systems. It adopts an electric pneumatic valve, powered by electrical signals and compressed air, and accepts input from the control system (0-10mA DC or 4-20mA DC)? The DC current signal is converted into the corresponding gas source pressure signal input and output by the regulator, which can achieve segmented control of the amplitude signal, thereby changing the valve opening displacement and achieving process parameter adjustment control of the fluid medium

　　2. ZJHP type pneumatic single seat regulating valve can be divided according to its operating mode;

　　Positive effect: Air closed normally open type (valve position shifts downward when signal pressure increases), Type B

　　Reaction: Air opening normally closed type (when the signal pressure increases, the valve position shifts upward), K-type

　　3. The ZJHP pneumatic single seat regulating valve is a straight through single seat cast spherical valve with a single seat plunger type valve core, which is particularly suitable for working environments where leakage is allowed to be small and the pressure difference between the front and back of the valve is not significant

　　4. The straight through low flow resistance single seat adopts a bottomless cover top guide structure, which only has one valve seat and one plunger shaped valve core. It has good sealing performance, small leakage, sensitive action, S-shaped fluid channel, small pressure drop loss, large valve capacity, flow characteristics, large adjustable ratio, large guiding area of the valve core guide part, and strong anti vibration performance. It is suitable for occasions with strict requirements for medium leakage and adjustment accuracy. However, due to the structural reasons of the valve, the unbalanced force on the valve stem is relatively large, especially under the condition of large nominal diameter, which is more obvious. Therefore, this valve is only suitable for occasions with small working pressure difference

　　5. By changing the design of the valve core shape; Different valve core shapes will result in different flow characteristics: logarithmic, linear, and fast opening characteristics

　　6. According to the requirements of the operating conditions, the valve core can be designed and manufactured; Soft sealing structure (suitable for acid-base, gas and other media that require tight sealing in the temperature range of -20~+120 ℃)

　　This series of products is widely used in the automation and remote control of industrial production processes such as chemical, petroleum, metallurgy, power plants, textiles, papermaking, and pharmaceuticals
