If you want to improve the service life, sealing performance, or flow characteristics of plastic diaphragm valves under certain working conditions, or if you want to carry out pneumatic transformation of diaphragm valves, or if you want to use diaphragm valves in more demanding environments (such as over 120 ° C, ultra pure environments, etc.), or if you want to replace imported diaphragm valves or expensive metal valves with similar user experience, please contact us, We have the richest technical experience and means in the industry, and have a large number of cases to help customers optimize their experience. We will do our best to help you.
Accurate Flow Control Diaphragm Valve
Features： The connection between the valve stem, valve stem nut, valve cover, handle, and limit cover is specially designed, so the flow stability and accuracy of the diaphragm valve are significantly improved.
Application Indication： Strict requirements for flow stability
High Temperature Corrosion Resistant Diaphragm Valve
Features： The connection between the valve stem, valve stem nut, valve cover, handle, and limit cover is specially designed, so the flow stability and accuracy of the diaphragm valve are significantly improved.
Application Indication： Strict requirements for flow stability
Slurry resistant diaphragm valve
Features： Using a single-layer rubber diaphragm made of wear-resistant, high-resilient EPDM, its life under slurry conditions is significantly longer than that of ordinary diaphragm valves and ball valves
Application Indication： Slurry environment containing fine particles in the medium:
Vacuum-proof diaphragm
Features： By improving the connection strength between the disc and the diaphragm, the service life under vacuum conditions is significantly improved.
Application Indication： Negative pressure conditions
The difference with ordinary diaphragm valve：
