Wholesale Dealers of Alloy Steel Globe Valve - Stainless steel valve BSP/NPT threaded – BESTOP

It’s the most widely used valve, belongs to the forced sealing valve, its closure principle is, rely on the valve bar pressure, so that the valve disc sealing surface and seat sealing surface close fit, prevent the medium flow.It has the characteristics of simple structure, good sealing, high fluid resistance and poor regulating performance

Globe valves are forced sealing valves, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak.It has the advantages of simple structure,convenient manufacturing and maintenance,small working trip,short opening and closing time,good sealing,long life.

Threaded swing check valve

The structure is swing type, except for the gasket and sealing ring used in the middle flange, there is no leakage point as a whole, which reduces the possibility of leakage of the valve. It has been used in many fields such as water supply, chemical industry, metallurgy, pharmacy and so on.

Stainless steel lift check valve:

Lift check valve is a regular valve. It is installed vertically, and its disc is positioned along the center to move up and down.

This strainer is conveying medium pipeline system indispensable a device, usually installed in pressure reducing valve, relief valve, calm water valve or other equipment inlet end, used to remove the impurity in the medium, to protect the valve and the normal use of equipment. Applicable medium for water, oil, and gas.
