ZJHJ precision small pneumatic thin film regulating angle valve

CHARACTERISTICS

Product model: ZJHJ

Product Name: Compact Pneumatic Thin Film Regulating Angle Valve

The ZJHJ precision small pneumatic thin film regulating angle valve adopts a top guide structure and is equipped with a multi spring actuator. It has the advantages of compact structure, light weight, sensitive action, S-shaped fluid channel, low pressure loss, large valve capacity, precise flow characteristics, and easy disassembly and assembly. Widely used for precise control of process parameters such as pressure, flow rate, temperature, and liquid level in gases, liquids, and other media to maintain them at given values. It is particularly suitable for regulating high viscosity fluids containing suspended solids and particulate matter with small leakage and small pressure difference before and after the valve, which can avoid coking, blockage, and facilitate self-cleaning and cleaning.
