ZJHJ pneumatic diaphragm angle control valve

ZJHJ pneumatic film angle regulating valve adopts top guide structure to adjust pressure, flow rate, temperature, liquid level and other parameters. Small volume, light weight, less leakage, simple flow path, small resistance, used in high pressure difference, high viscosity, containing suspended substances and granular substances liquid regulation, can avoid coking, clogging, but also easy to self-cleaning and water cleaning, angle valve is generally used in the bottom in and out of the occasion, because this can make the regulation better.
