Product use
Life check Valve adjusting the production process is an important part of the system, among other things, control the flow of one-way media tube of the valve to prevent the media back .
Features
1, lift-type check valve has a simple structure, reliable action, easy maintenance, etc., are widely used in purification equipment, petroleum, chemical industry, metallurgy, electric power, textile production process, etc.
2, when the medium flows from the valve body shown in the arrow to enter the body, the role of media in the pressure valve to produce thrust upward, when the medium is greater than thrust gravity valve, the valve opens. When the medium pressure valve after the valve in the valve with the valve of the force of gravity is greater than their own before the pressure valve in the power valve, the valve closed to prevent the media back
