Product Description

Product name	Pneumatic eccentric half ball valve
Product Model	EQ647F/Y
Nominal diameter	DN25-DN800
Pressure range	1.6-6.4 MPa
Body material	Cast iron, cast steel, stainless steel

Ball valve  Features: (1) small fluid resistance, full diameter ball valve basically no flow resistance. (2) Simple structure, small size, light weight. (3) Compact. It has two sealing surfaces, and at present, the sealing surface material of the ball valve is plastic, which has good sealing property and can achieve sealing. It has also been used in vacuum system. (4) Easy to operate, open and close fast, from full open to full close as long as the rotation of 90 degrees, easy to remote control. (5) Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient. (6) When fully open or fully closed, the sealing surface of the ball and the seat is isolated from the medium, and the medium will not cause the erosion of the sealing surface of the valve. (7) Wide application, small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied. (8) Because the ball valve has wipeability in the opening and closing process, it can be used in the medium with suspended solid particles.

Pneumatic eccentric half ball valve overview:
Pneumatic eccentric half ball valve adopts the spring loaded movable seat structure, the seat and the ball will not produce blockage or detachment and other problems, the use of long. There is a shearing effect between the ball core and the metal seat with V-shaped incision, which is suitable for the medium containing fiber, small solid particles and slurry. Control the pulp appearance of the paper industry. The opening and closing parts adopt V-shaped spherical structure, which solves the problem that the valve cavity is easy to deposit medium. When the valve is fully opened, the flow capacity is large and the pressure loss is small. Compact structure, strong versatility, flow characteristics of approximate equal percentage, adjustable larger. Worm gear drive V-type ball valve also has the function of adjusting and positioning. V-type ball valve is suitable for Class150 ~ 600, PN1.6 ~ 10.0MPa, working temperature ≤200ºC on the pipeline, used to adjust the pressure and flow of the medium of the section pipeline, the selection of different materials, can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, ammonia brine, neutralizing water and other media.
