The connection between the valve stem, valve stem nut, valve cover, handle, and limit cover has been specially designed, significantly improving the flow stability and accuracy of the diaphragm valve.
Suitable for situations where strict requirements are placed on flow stability.
The connection between the valve stem, valve stem nut, valve cover, handle, and limit cover has been specially designed, significantly improving the flow stability and accuracy of the diaphragm valve.
Suitable for situations where strict requirements are placed on flow stability.
The use of a single-layer rubber diaphragm made of wear-resistant and high-rebound EPDM material significantly improves the service life under slurry conditions compared to ordinary diaphragm valves and ball valves.
Suitable for slurry environments containing fine particles in the medium.
By improving the connection strength between the valve disc and diaphragm, the service life under vacuum conditions is significantly increased.
Suitable for negative pressure (vacuum) conditions.

If you want to improve the service life, sealing performance, or flow characteristics of a plastic diaphragm valve under specific working conditions, or if you need to upgrade it to pneumatic operation, or use it in more demanding environments (such as temperatures above 120°C or ultra-clean conditions), or replace imported diaphragm valves or expensive metal valves based on similar application experience, please contact us.
We have extensive industry experience and technical expertise, along with numerous successful cases, to help customers optimize performance and achieve the best possible results.
