Selection Of Valve Body

Sep 13,2021

● Ball Valve

Ball valve uses a ball with a circular hole as the opening and closing part, and the ball rotates with the stem to realize the opening and closing action of the valve. The ball valve is mainly used to cut off, and change the direction of the flow in the pipeline. The V-shaped ball valves also have good flow regulation function.
It is suitable for common media such as water, solvents, acids and natural gas, and also for media with harsh working conditions such as oxygen, hydrogen peroxide, methane and ethylene.

● Sanitary Ball Valve

The sanitary ball valve body is made of stainless steel, and the inner wall is electronically polished by 0.5um (240Grit) to ensure unobstructed fluid flow. The all-inclusive PTFE on the sealing surface has no dead angle and ensure the cleanliness. Sanitary ball valve is widely used in beer industry, food industry, chemical industry, pharmaceutical industry, bioengineering and water treatment industry.

● Wafer Type Flanged Ball Valve

Compared with the normal flanged ball valve, the wafer type flanged ball valve has the characteristics of compact structure, small volume, light weight, close distance between the valve seat and the end flange, less material retention and superior sealing performance. Generally, the wafer type flanged ball valve is suitable for site where the installation position is relatively short, and is widely used in the automatic control of chemical, petroleum, biopharmaceutical, HVAC, vacuum equipment, light industry and other industries.

● Butterfly Valve

Butterfly valve uses a circular disc which rotates with the valve stem to open, close, and regulate the flow. Butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate, and also has good flow regulating function and sealing performance. Butterfly valve is the main valve used In the field of large and medium caliber, medium and low pressure.

● Sanitary Butterfly Valve

Sanitary Butterfly Valve uses tri-clamp connection, which has the advantages of simple structure, quick assembling and disassembling, small fluid resistance, safe and reliable use. All steel parts are made of acid resistant stainless steel, and sealing material is food grade silicone rubber or PTFE, in accordance with food grade specifications. Sanitary Butterfly Valve is widely used in food, wine, beverages, dairy products, fine chemicals pharmaceutical and biological engineering and many other industries.

● UPVC Butterfly Valve

UPVC Butterfly Valve has light weight and corrosion resistance, which is used in a variety of fields such as water purification and drinking water pipeline systems, drainage and sewage pipeline systems, brine and seawater pipeline systems, acid and Alkali and chemical solution systems.

● Tri-eccentric Metal Hard Seal Butterfly Valve

Tri-eccentric Metal Hard Seal Butterfly Valve adopts tri-eccentric Structure Design, no friction between valve plate and valve seat which eliminating the leakage caused by seat wear of Rotary Control Valve. The valve seat adopts multi-layer structure, using the perfect combination of metal and non-metal materials to form a sealing surface, which can be used well under high and low temperature working conditions. It is now widely used in petrochemical industry, defense and military industry, aerospace industry, electric power equipment, iron and steel metallurgy, nuclear industry, etc.

● Vented Butterfly Valve

Vented Butterfly Valve is a non-closed butterfly valve, suitable for ventilation, environmental protection projects, containing dust cold air or hot air gas, medium temperature ≤300 °C of the pipeline. It is mainly used in steel metallurgy, petrochemical, power equipment, glass industry, coating equipment, coating equipment, drying equipment and other industries.
