5, due to PTFE and other materials with good self-lubricating, and the ball friction loss is small, so the long life of the ball valve. 6, the lower part of the stem and stem stem to prevent the stem stem spray, such as fire caused by stem seal damage, convex and the valve body...
The utility model provides a frictionfree twin core ball valve which has the advantages of flexible switching, good tightness and long service life. The utility model is composed of a valve body, a lower sleeve, a valve core, a valve rod, an upper sleeve, a valve cover, filler, a valve...
A butterfly valve should have a range of possible shaft diameters for each nominal valve size in order to handle the variation in torque due to various operating pressure conditions and packing box friction. Shafts should not be made of material prone to creep, such as some austenitic stainless...
·Its flow is simple and fully forms straight channel when full open,with minimum pressure loss. ·Ball valve rotate 90 ° seated fully open/close fastly. Low friction coefficient and small operating torque. ·Good sealing. A variety of the seat material and wide adaptation. ·Handle operation...
Plumbing system is an important section in any building. This blog will focus on different types of ball valves used in plumbing.
1, the fluid resistance is small, the valve is fluid resistance all valves in a minimal, even reduced diameter valve, the fluid resistance is quite small.2, the stem thrust bearing reduces friction torque, can stem the long-term stable and flexible operation.3, the valve seat sealing ...
