D673W D673W-10 D673W-16 Pneumatic butterfly valve

Overview of D673W D673W-10 D673W-16 Pneumatic butterfly valve

D673W D673W-10 D673W-16 Pneumatic butterfly valve is composed of butterfly valve with multi-level metal hard seal structure or rubber soft seal structure and high-precision pneumatic actuator. It is suitable for two position switch and cut-off occasions, also known as pneumatic cut-off butterfly valve. The external travel limit switch, solenoid valve, triplet and 0.4-0.7mp a air source can realize the switching operation, and send two pairs of passive contact signals to indicate the switching of the valve. Pneumatic switch butterfly valve is powered by compressed air. The valve stem drives the valve core to rotate 9 ℃ in the valve body, which can realize the action of full opening and full closing.

Features of D673W D673W-10 D673W-16 Pneumatic butterfly valve

(1) The pneumatic switch butterfly valve has the advantages of simple and compact structure, light weight, easy installation and disassembly and convenient maintenance.

(2) the pneumatic cut-off butterfly valve adopts stainless steel "U" seal ring, which has certain elasticity. It has excellent sealing with the butterfly plate under high and low temperature

(3) After strict calculation, the three-dimensional eccentricity of pneumatic switch butterfly valve has almost no friction between "1" seal ring and butterfly plate, long service life, and has the function of closing more and more tightly.

(4) The sealing surface of the butterfly plate of the pneumatic cut-off butterfly valve is overlaid with cobalt based cemented carbide, which has wear resistance and long service life;

(5) The pneumatic switch butterfly valve has a unique structure. The "switch" can be completed only by turning the valve stem 90 °. The operation is flexible, convenient, labor-saving, not affected by the medium pressure, and the sealing performance is reliable.
