Ball Valve sealing performance

Equipment manufacturing industry is the development of the oilfields of Daqing need to create a hundred years. Century to achieve the sustainable development of oil fields, you need to doto support the equipment manufacturing industry. With theincreasing difficulty of oil development, need to further improve thetechnology; development of petroleum equipment manufacturing industry is engaged in the petroleum equipment manufacturing of large enterprises, especially the city is not listed in the petroleumequipment manufacturing enterprise for sustainable development.Good service for the oil industry, oil equipment manufacturingenterprise survival and development of the fundamental.

Ball Valve,can be divided into electric andpneumatic . In coal chemical and petrochemical companies, the proof is very important. So in these two categories of enterprises, mostly used in pneumatic control valve.

In these two industries, Mostly Check Valve, high pressure, stable performance. Butterflywith a less than normal, subsidiary industries more.

Globe Valve for furnace, gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical refining and power generation and environmental protection engineering systemstransport all kinds of corrosive, non-corrosive fluid media pipeline,for regulating and cut off media flow.
Valve sealing performance is part of the valve to prevent medialeaks of the sealing ability, it is the valve of the most importanttechnical performance indicators.
