Connction mode:welded, quick-install, threaded, flanged clamp-type. Material quality:SUS304, SUS316L Flux domination of pipeline:DN25-150&1"-6", applied to the stainless steel pipeline system. Working principle:remote-controlled operation by the driving gear or manual operation by handle. Three drive forms:often the closing type, often opening type is pneumatic or manual type.

Ball valves are mechanical devices used to control the flow of gas, oil, water and other fluids. The ball has a port through the middle so that flow occurs when the port is in line with the ends of the valve. When the valve is ‘closed’, the port is perpendicular to the ends of valve, thus blocking the flow. By turning the handle or handwheel attached to the valve, the flow of the fluid is regulated. Materials used for making ball valves can be of carbon steel, stainless steel, duplex stainless steel and alloy, etc

Butterfly valves are quick opening valves that consist of a metal circular disc or vane with its pivot axes at right angles to the direction of flow in the pipe, which when rotated on a shaft, seals against seats in the valve body. They are normally used as throttling valves to control flow.Unlike ball

There are various types of check valves used in a wide variety of applications, such as diaphragm check valve, piston check valves, swing check valve. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, many check valves are very small, simple, and/or cheap
