The V-type ball valve combines the optimal control characteristics of the ball valve and the butterfly valve. Its development is closely related to the advancement of technology. Today, the product is widely used because it has the following advantages.
(1) The integral valve body, without any pipe flange joints, avoids the influence of pipe or bolt stress on the sealing performance of the valve body. Because the valve body does not have any pipe joints, the pressure-resistant casing is not subject to pressure “mutation”;

(2) A V-type ball valve has a V-shaped valve core, which can ensure the accuracy of control over the entire measuring range even in the case of small flow or high viscosity medium;

(3) The leak-proof and durable valve seat of the V-type ball valve is lined with a PTFE cup or O-ring with a stainless steel inner core at its outer diameter. The valve seat is made of stellite carbide with a large cross section. ;

(4) When the V-type ball valve is closed, the V-notch and the valve seat produce a strong shearing action, and have a self-cleaning function to prevent the core from being stuck, so the pneumatic V-type ball valve is particularly suitable for the fluid that freezes in a pipeline or contains fibers and particulate solids.
