The Comparison of No Lining Diaphragm Valve and Electric Diaphragm Valve
No lining diaphragm valve
Unsealed Diaphragm Valve body is made of cast steel or stainless steel, PTFE or other rubber can be used as the diaphragm, close cooperation between the valve body and the diaphragm provided with the valve seal and valve seat seal, to ensure that the pipeline internal and external environment completely isolated .
Product description:
Non-liner diaphragm valves are designed to control non-corrosive or normally corrosive media, elastomeric seals, to ensure that there is no internal leakage.
Working principle:
The sanitary diaphragm valve is opened and closed by the stem up and down movement. When the stem is in the upper position, the spherical diaphragm is bent upward to form a conductive state. When the valve stem drove the valve core to bend the diaphragm from top to bottom movement, forced diaphragm tight seat area, or closed the pipeline fluid to the path.
Features:
1, the diaphragm can be replaced, low maintenance costs.
2, no stuffing, no leakage
3, streamlined flow channel made the pressure loss.
4, the elastic seal of the opening and closing parts, ensured no leakage.
5, the valve body and cover separated by the middle diaphragm, making the top of the diaphragm cover, stem and other parts from the media erosion.
Electric diaphragm valves
Electric diaphragm valve body is made of cast steel or stainless steel, PTFE or other rubber is the diaphragm, the valve body cooperated with the diaphragm closely, the valve seal and valve seat seal ensured that the pipeline internal and external environment completely isolated.
Product description:
Electric diaphragm valve regards 380V voltage as the signal to control the opening or closing the diaphragm, we can choose intelligent adjustment type Denso. Sanitary diaphragm valves are composed of electric actuators, with electric actuators to drive the diaphragm valve switch, so as to achieve the media in the pipeline cut off and connected. Valve lining the different plastic, can be resistant to varying degrees of corrosive media.
Working principle:
Electric diaphragm valve is opened and closed by electric actuators driven stem up and down movement to achieve. When the stem is in the upper position, the spherical diaphragm is bent upward to form a conductive state. When the valve stem from top to bottom movement to drive the valve core to bend the diaphragm, forced diaphragm tight seat area, or closed the pipeline fluid to the path.
Features:
1, the diaphragm can be replaced, low maintenance costs.
2, streamlined flow channel made the pressure loss.
3, the elastic seal of the opening and closing parts ensure that no leakage.
4, the fluid channel is straight, so fluid loss is smaller, less wear.
5, the valve body and cover separated by the middle diaphragm, making the top of the diaphragm cover, stem and other parts from the media erosion.
6, because the seal is a flexible rubber diaphragm, so it also has good sealing and minimum closing force.
7, pneumatic diaphragm valve body cavity surface has a variety of rubber.
