Segment Ball Valve

Segment ball valve is one type of ball valves. lts closure is a half ball with V type port which has sharp edges.During operating the valve, friction action will be occurred between its closures that producing a strong shearing forceto the medium, and a fan-shaped area will be formed between V type port of the ball and the port of seat ring, so thesection area of flow port can be changed, and the medium can be precisely regulated. lt is a kind of regulating valvewith angle rotation, having same sealing performance as common ball valves, so it simultaneously has both functionsof reaulatina and on-ot. incorporatina with oneumatic or electric actuators, it can be widelv used in the automaticcontrol systems in different industries.

Integral structure of Body : Both wafer type and flanged type V-type ball valves are with integral, side-entrystructure which has strona rigidity, makina it hard to be deformation and leakage.

With lower and upper self-lubricated bearings: Lower and upper self-lubricated bearings are installed inside thebody. So the contact surface with stem is bigger which have a high carrying capacity and low friction coefficient, that operating torque of valve is reduced.

Seat rings can be metal seats or PTFE soft seats depending on different workina medium, Sealina face of metalseats will be overlaid with hard alloy, while ball surface is hardened with hard chromium plated or spraying overlayplasma nitriding, etc, so as to increase working life of sealing faces and improve temperature resistance. PTFE orRPTFE seats have excellent sealing performance, high corrosion resistance and wide applications.

Economical practicality: ight body weight, small stem torque, so it can be installed with smaller pneumatic orelectric actuators, high cost-effective compared to same size/class of other kinds of regulating valves.

Wide applications: With the shearing action between V port and seat ring, also with smooth body internal surfaceso making the medium is not easy to be kept in the body, So it is not only suitable for liauid medium, but also better forusing in control system of mediums contained fibers and solid particles.

Precise control of small fiow: Through special machining on the V port for small sizes, which can achieve a precisecontrol of low CV value.
