First, the flange V-type pneumatic ball valve overview:

The flange V-type pneumatic ball valve adopts the movable valve seat structure loaded by the leaf spring, and the valve seat and the ball body do not have problems such as jamming or detachment, the sealing is reliable, and the service life is long. The V-type ball valve spool is designed as a V-notch with a special switch. It has large flow capacity, low pressure loss, accurate shut-off characteristics and control functions, and the flow characteristics are approximately equal percentage. The opening and closing member adopts a V-shaped spherical missing structure, which completely solves the problem that the valve cavity is easy to deposit medium. The flange V-type pneumatic ball valve is composed of a double (single) acting pneumatic piston actuator and a quick-loading ball valve. The pneumatic piston actuator is made of low friction material and is made of bearing sleeve. The inner and outer surfaces of the cylinder are hard anodized and anticorrosive, which greatly improves the service life of the cylinder. This product has stable performance and is widely used in petrochemical, metallurgy, electric power, food and other industrial sectors.

Second, the characteristics of the flange V-type pneumatic ball valve:

1, compact structure, small size, can be installed in vertical and other advantages.

2, with excellent adjustment characteristics: V-type ball valve has an approximate equal percentage of inherent flow characteristics and adjustable ratio of up to 300:1. Therefore, the V-valve provides precise control over a wide range of variations.

3. Maximum flow volume: Due to its streamlined shape and full right angle rotation control, the maximum volume is extremely high, the flow capacity is particularly large, and the flow resistance is small, so a smaller and more economical valve size can be used.

4. The V-type ball valve adopts double bearing structure, high mechanical stability and small starting torque, which ensures the valve has good sensitivity and induction speed.

5, reliable (safe): the valve body is a whole, sturdy and durable, the operation is not affected by the pipeline pressure, and can avoid leakage of the valve body.

6. Excellent sealing of metal valve seat: V-type ball valve adopts movable metal valve seat, self-compensation function, and has superior sealing performance and service life. In the flow direction, the leakage amount is ≤10-6×rated flow coefficient.

7. Super shearing capacity: V-type ball valve adopts metal hard seal structure, V-shaped ball valve core and metal valve seat are in the process of turning. V-notch and valve seat produce a strong shearing force to cut fiber and other impurities. And has a self-cleaning function to avoid valve jamming.
