When the ball PP valve rotates 90 degrees, it should show a spherical surface at the inlet and outlet, so as to close the valve and cut off the flow of the medium.

Advantages of PP ball valve：

The PP ball valve is not restricted by the installation direction, and the flow direction of the medium can be arbitrary. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.

The PP ball valve has a simple structure, relatively small size, light weight and easy maintenance.

Close and reliable. It has two sealing surfaces, and the current sealing surface materials of ball valves are widely used in various plastics, which have good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.

PP ball valve is suitable for frequent operation, opening and closing quickly and lightly. It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for remote control.

The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and it is convenient to disassemble and replace.

PP ball valve has good sealing performance. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.

It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.

Because the PP ball valve has wiping properties during the opening and closing process, it can be used in media with suspended solid particles.

9. PP ball valve has low fluid resistance, no vibration and low noise.

The PP electric air valve produced by XICHENG EP LTD is mainly used in PP material ventilation duct system, connected with PP air duct, used for corrosive gas extraction and exhaust control, anti-corrosion acid and alkali resistance, PP electric air valve has complete specifications, supporting PP Air ducts, elbows, tees, and variable diameters are used to form a complete PP ventilation duct system. The damper body below ø315 is injection-molded, and the body above ø315 is custom-made by coil.

PP electric air valve is a kind of non-sealed butterfly valve, which is widely used in universities, chemical industry, biology, electric power, energy, environmental engineering, etc. in the production process, the medium temperature is less than or equal to 90℃, and the nominal pressure is less than 0.1Mpa. , Open and close or adjust the medium, usually installed on the top of the fume hood, the top of the PP suction hood, and the inlet of the pipeline of the one-use and one-standby spray tower, as a switch to the exhaust gas flow direction of the PP spray tower.

PP electric air valve principle

The PP electric air valve is installed in the PP pipeline system. Through manual operation or PLC automatic control technology, the PP electric air valve can be opened and closed according to the needs. Drive the rotation of the butterfly valve blade to achieve a 90-degree angle, achieve the purpose of opening and closing, and have a feedback indication function. Through the differential pressure detection device, after closing the air valve, the signal is transmitted to the PLC system, so as to control the PP fan inverter to reduce the speed and save energy.

(1) The takeover standard of the split multi-leaf air volume dispatching valve is the same as the rectangular air duct standard of the national ventilation duct standardization.

(2) The blades of the air volume dispatching valve are side-opening and forward-opening, which are used as dispatching valves in ventilation, air dispatching and air purification systems.

(3) According to the test, the air-tightness of the air volume dispatching valve is good, and its relative air leakage is about 10%, and the dispatching performance is good.
