The three-way globe valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the globe valve disc to force the sealin

The opening and closing part of the angle globe valve is a plug-shaped valve disc, the sealing surface is flat or conical, and the valve disc moves li

It relies on the globe valve stem pressure to tightly combine the valve disc sealing surface with the valve seat sealing surface to prevent the flow o

By making the sealing surface into a tapered shape and narrowing the contact surface, the sealing stress of this seal is greatly increased under a cer

The sealing pair of the globe valve can use metal seal and soft seal. When using metal seals, not only does the sealing stress need to be high, but it

If the medium flowing in from the upper part of the gobe valve disc may cause the valve disc to detach from the valve stem, or cause a component to fa

The working principle of the globe valve is to use the torque of the valve stem to exert downward pressure on the sealing surface, and rely on the pre

· Friction-free opening and closing: This function completely solves the problem of traditional ball valves that affect the seal due to frictio

Fully welded pipeline ball valves have the advantages of fast opening and closing, small flow resistance, compact structure, light weight and reliable

When one of the valve sealing pairs uses an insulator, such as rubber, plastic, etc., static electricity will be generated due to friction during the

When pipelines transport toxic, flammable, explosive and highly hazardous media, ball valves are often required to have a fire-resistant structure in

Ball valves often rely on the front or rear valve seat to achieve one-way sealing. Only in very special occasions are the front and rear valve seals u
