Working Principle:

With the external power provided by the cylinder or handwheel, the valve stem drives the valve plate to move up and down to achieve the opening and closing of the valve. During the opening and closing process of the valve, the pre tightening force of the spring set between the double gate plates ensures that the valve plate and valve seat are in close contact, achieving sealing. among which,Z644TC ceramic pneumatic double gate valveThe working principle of the valve is that when the air source is introduced from the upper intake port, the valve stem drives the valve plate to move downward and the valve closes. When the gas source is introduced from the lower air inlet, the valve stem drives the valve plate to move upward, and the valve opens. A spring is loaded between the valve plate and the valve seat, and the spring force always presses the valve plate against the valve seat to ensure the sealing of the valve. It also allows the valve plate to move vertically up and down, which helps to compensate for the thermal expansion and contraction of valve parts, overcome the impact of any back pressure changes on the seal, and prevent particle media from entering between the two sealing surfaces. During the opening and closing process, the valve plate can rotate on its own, causing grinding and polishing between the sealing surfaces. Moreover, due to the eccentricity of the valve body to the channel, a vortex will be generated when opening and discharging materials, and the material vortex formed will clean the valve cavity on its own. All of these features make this valve have an extremely long service life, providing a reliable guarantee for the safe operation of your system.

Installation instructions:

　　 Welcome to choose our company's products. In order to extend the service life and improve work efficiency, this valve should be installed upright as much as possible during installation. Install at a 45 degree angle if conditions do not permit. In the case of inverted or horizontal installation, the empty delivery time must be extended to avoid valve volume dust.
