The difference of full seal and half seal for sanitary ball valve

July 29, 2023

The difference of full seal and half seal for sanitary ball valve. Customers often ask me about sanitary ball valve, but they are not clear that the sanitary ball valve has half seal and full seal. The reason why the sanitary valve is called sanitary is mostly because its internal structure is designed hygienically, not just polished.

What are the characteristics of the diaphragm valve?

June 30, 2023

The most prominent feature is that the diaphragm valve separates the inner cavity of the lower valve body from the inner cavity of the upper bonnet, so that the valve stem, valve disc and other parts above the diaphragm are not corroded by the medium, eliminating the need for packing and sealing structure, and will not produce medium outside. leak.

What are the solutions to pump mechanical seal leakage?

February 27, 2023

Mechanical seal is also known as face seal, which has a pair of end faces perpendicular to the axis of rotation. Under the action of fluid pressure and compensating mechanical external elastic force, the end face depends on the auxiliary seal to keep fit with the other end, and relative sliding, so as to prevent fluid leakage.
