ZJHS pneumatic diaphragm angle control valve
Other Products
I. Introduction:
The ZJHS pneumatic diaphragm angle control valve is especially suitable for regulating occasions with small allowable leakage, small pressure difference between the front and rear of the valve, high viscosity, and media containing suspended solids and granular substances. It can avoid coking and clogging, and is convenient for self-cleaning and washing. It adopts a top-guided structure, and is composed of a multi-spring pneumatic diaphragm actuator and an angle control valve body. The pneumatic angle control valve has the advantages of compact structure, light weight, sensitive action, streamlined fluid channel, small pressure drop loss, large valve capacity, accurate flow characteristics, and convenient disassembly and assembly. When matched with an electric valve positioner, the pneumatic diaphragm angle control valve can realize automatic adjustment and control of the fluid medium in the process pipeline. It has the characteristics of small size, light weight, top-guided valve core, simple flow path, small resistance, and easy flushing. It is widely used in the precise control of media such as gas and liquid, keeping process parameters such as pressure, flow, temperature, and liquid level at given values.
II. Features:
1. Top-guided, bottom-inlet and side-outlet, simple flow path, small resistance, and large valve capacity.
2. Large adjustable range, with an inherent adjustable ratio of 50, and the flow characteristics include linear and equal percentage.
3. The actuator adopts a multi-spring structure, with both height and weight reduced by 30%.
III. Application:
The valve body is right-angled, the valve core is of single-guided structure, and the valve body has a simple flow path and small resistance. It is especially suitable for regulating high-viscosity fluids containing suspended solids and granular media, and can avoid coking, adhesion, and clogging. The diaphragm angle control valve adopts a top-guided structure, and is composed of a multi-spring diaphragm actuator and an angle control valve body, with the advantages of compact structure, light weight, sensitive action, streamlined fluid channel, small pressure drop loss, large valve capacity, accurate flow characteristics, and convenient disassembly and assembly.
