Three-piece quick-fit ball valve

Three-piece ball valve connection methods are very diverse, internal thread, industrial thick-walled pipe welding, sanitary pipe thin-walled pipe butt welding (can be used with automatic welding machine to provide extended automatic welding), sanitary pipe quick installation, sanitary pipe sanitary flange, national standard Pipeline GB flange, etc.

The three-piece ball valve body adopts the advanced technology of precision vacuum wax mold casting, with reasonable structure and beautiful appearance. The valve seat adopts an elastic sealing structure, which is reliable in sealing and easy to open and close. The valve stem adopts a bottom-mounted structure with an inverted seal. When the valve cavity is abnormally boosted, the valve stem will not be flushed out.

The three-piece ball valve body can be equipped with international standard ISO high platform and locking device, and can be equipped with pneumatic actuators, electric actuators, valve position feeders, mechanical positioners and intelligent positioners, which can meet various process automation requirements. need.

• The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.

• Simple structure, small size and light weight.

• Tight and reliable. At present, domestic PTFE and imported PTFE are widely used for the sealing surface materials of ball valves, which have good sealing performance and are also widely used in vacuum systems.

• Easy to operate, open and close quickly, just rotate 90° from fully open to fully closed.

• Easy maintenance, simple structure of ball valve, generally movable sealing ring, easy disassembly and replacement.

• When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and the sealing surface of the valve will not be eroded when the medium passes through.

• Sealing characteristics: Semi-package sealing is used in processes without special requirements, and a full-package sealing structure can also be provided for special processes.

• Drive mode: manual, with high platform can be equipped with drive (pneumatic, electric)

•Nominal diameter: DN10~DN100 ISO12.7~101.6

•Nominal pressure: 1.0MPa

•Applicable temperature: domestic PTFE -10~100℃, imported PTFE -10~150℃

•Applicable medium: gas, water, oil

•Available drive: manual, pneumatic, electric

• Connection standard: quick release

• Body material: CF8(304), CF3(304L), CF8M(316), CF3M(316L)
