Provide 3PC Stainless Steel Ball Valves with ANSI, DIN, BS, GOST Standard

3PC Stainless Steel Ball Valve

3PC Stainless Steel Ball Valve and Gate Valve belong to the same type of valve, the difference is that its switching piece is a sphere, and through the rotation of the central axis of the sphere to cut off, distribute and change the direction of flow of the medium. It has been widely used for its advantages of low resistance, simple structure, tight and reliable, easy operation and maintenance.

Composition:

Its valve body consists of 2 sub-bodies and a main valve body, 3 of which are connected by bolts or threads. It is easy to install, dismantle and clean. Other components are: ball, stem, sealing ring, packing and operating device. The production process of each component is different, the ball can be obtained by casting or forging after CNC machining, you can also directly use CNC machining stainless steel rods to obtain, the valve body is the use of precision casting to obtain because the precision casting can save more materials and subsequent processing costs, the valve stem is more direct use of CNC machining or in the forging after processing to obtain.

Classification:

 According to its connection with the pipeline can be divided into flange type, welded type and threaded type, according to the internal structure can be divided into floating ball type, fixed ball type, and elastic 

ball type, according to the position of its channel can also be divided into straight-through, three-way type and right-angle type.

Material:

The ball, valve body and valve stem are made of 304, 316 or 316L stainless steel. Seals are mostly PTFE, PFA or metal. Seat and packing are PTFE.

Standard:

The usual standards are ANSI, DIN, BS, GOST, and in the case of food and pharmaceutical applications, national food and pharmaceutical valve standards such as FDA and GMP.

Application:

Mostly used in petrochemical, food and pharmaceutical, water treatment, papermaking, metallurgy, electric power and other industries of fluid control.
