Pressure and temperature
1. Single-piece valve body
V control ball valve have single-piece bodies, which prevents leaks caused by separate flanges.
V-ball adapt the upper and lower stem to fixed by bearings. Bearings are by composite material, it have good lubricating, strong abrasion performance, high mechanical stability, small torque for opening, to ensure the valve with excellent sensitivity and sensor speed.
3. Movable seat
V-ball valve adapt the belleville washer or column spring loaded movable seat structure, , the seat can make the best contact with the disc by the springs'return force, and has good sealing performance. PTFE seat and metal seat are available for different application requirements.
4. V segment ball
Specially designed V-segment ball provides equal percentage flow characteristic with high precision control performance as well as strong cutting force and self-cleaning function.
5. Spline connection between shaft and ball(for 10" and above)
Ball and shaft are connected by spline. It provides a seamless match ball with shaft is prevented with enhanced control precision.
6. Low capacity
For super-low flow applications, low capacity valve are available with DN25 for precise control.
7. ISO5211 direct mounting pad
V control valve built with ISO5211 direct mounting pad. It conveniently connect with various kinds of drive, such as the handle, worm gear, pneumatic actuators, electric actuators, hydraulic actuators etc.
8. Full Silica sol Investment Casting body
The V-port control ball valves' body are Full Silica sol Investment Casting, so it have very smooth surface, it also more beatiful.
The main materials of the KEMUS’S products are WCB, WCI, WC6, WC9, 2GCr5Mo, CF8, CF8M, CF3, CF3M, titanium alloy and Monel. The parts of the valve are processed by CNC machine tools to ensure the accuracy and interchangeability of the products. The valve sealing surface is the first to adopt advanced plasma surfacing equipment and high temperature resistant Sitali cobalt-based hard alloy material. The valve seat structure is made of different materials and different. Material inlaid welded seat
