Product Name: Pneumatic Expansion Powder Butterfly Valve

Product Model: YFPZD671F/YFPZD641F

Product specifications: 2 inches -12 inches

Product material: 304, 316, 316L

Product Description
The unique design principle of the expansion type powder butterfly valve: The gas pressure causes the valve seat to extend towards the valve disc, facilitating the stable distribution of pressure for sealing at any time. When the valve is opened and closed, the valve disc and the valve seat do not come into contact, and there is no friction between the valve disc and the valve seat. For a common butterfly valve, the friction between the disc and the valve seat will reduce the performance and service life of the valve.
Only a small torque is required to open and close the valve, and a smaller actuator can be used.
Experiments and documents have proved that the expansion butterfly valve is superior to all other valves. The service life of the expansion butterfly valve can reach 1 to 3 million times. It is particularly suitable for powders, gases, liquids, etc
Size range: 2" (50mm) to 12" (300mm), suitable for flange standards such as American standard, German standard and Chinese standard.
Standard configuration: 1 valve, 1 actuator, 1 limit switch, 1 control device. According to customer requirements, it can be upgraded to: material distribution valves, metering valves, etc
