Papua New Guinea Hydraulic ventilation butterfly valve
Product Description
The hydraulic ventilation valve is made of the same material as the valve body to form a sealing ring. Its adaptation temperature depends on the material selection of the valve body. It is generally applicable to industrial, metallurgical, environmental protection and other pipelines for ventilation and adjustment of medium flow. It has the functions of diversion, cut-off, adjustment, throttling, check, shunt or overflow and pressure relief.
Hydraulic ventilation valve can be used to control the flow of water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids and other types of fluids. The working pressure of the valve can be from 0.0013MPa to 1000MPa ultra-high pressure, and the working temperature can be from -269 ℃ ultra-low temperature to 1430 ℃ high temperature.
The main features of hydraulic ventilation control valve are:
1, the design is novel, reasonable, unique structure, light weight, open and close quickly.
2. Small operating torque, convenient operation, labor-saving dexterity.
3, the use of adaptive materials to meet different media temperature machine corrosive media.
Ventilation control valve according to the transmission form is mainly divided into manual, electric, hydraulic, pneumatic, worm gear drive, etc., can be under the action of pressure, temperature or other forms of sensing signals, according to the predetermined requirements of action, or do not rely on sensing signals and simple opening or closing, the valve relies on the drive or automatic mechanism to make the opening and closing parts for lifting, sliding, swing or rotary movement, so as to change the size of its flow area to achieve its control function.
