Stainless Steel Wafer Type Ball Valve Q71F

Date:[2016-10-20]    hits: Stainless Steel Wafer Type Ball Valve Q71F

Overview of Wafer Type Ball Valves

This product has the advantages of short length, light weight, convenient installation and material saving compared with the ordinary ball valve with reference to the characteristics of Italian products. The folder insulation jacket ball valve insulation effect. In addition, the valve seat with elastic seal structure, reliable sealing, opening and closing easily. With a fire-resistant structure, in case of fire, can still operate reliably and have good sealing. According to user needs, can be equipped with anti-static structure. Set the 90 ° switch with a hole positioning film, according to need to be locked to prevent misuse.

Application: The ball valve and the folder folder on the jacket jacket ball valve for Class150, PN1.0 ~ 2.5MPa, operating temperature 29 ~ 180 ℃ (PTFE ring for enhanced PTFE) or 29 ~ 300 ℃ (for the ring position Polystyrene), for the cut-off or connected to the pipeline in the medium, the use of different materials, can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing media, urea and other media .

Applicable medium: water, gas, oil, natural gas and acid-base corrosive media.

Applicable temperature: -20 ~ 150 ~ 300 ℃

Wafer-type butterfly valve structure is simple, small size, light weight, only by a few parts. And only need to rotate 90 ° to quickly open and close, simple operation, while the valve has good fluid control characteristics. When the ball valve is in the fully open position, the valve plate thickness is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics. Tower valve has a bomb seal and metal seal two seal types. Elastic seal valve, ring can be embedded in the valve body or attached to the valve plate around.

Valves with metal seals generally have a longer life than elastically sealed valves, but they are difficult to completely seal. Metal seals can be adapted to higher operating temperatures, and elastomeric seals have temperature-limited defects.

If a ball valve is required for flow control, it is important to select the correct size and type of valve. Ball valve structure is particularly suitable for the production of large diameter valves. Ball valve not only in oil, gas, chemicals, water treatment and other general industry is widely used, but also used in thermal power plant cooling water system.

Commonly used ball valve and flange ball valve on the clip-type two. Wafer-type ball valve is to use double-headed bolts to connect the valve between the two pipe flange, flange valve with a flange on the valve, the valve flange on both ends of the flange connected to the pipe.
