PRODUCT

CA Series Cage Control Valve

CA Series Cage Control Valve

CA Series Cage Angle Control Valve is an extended production of CGP and CGN, apart from different body types, the rest is entirely the same with interchangeable trim parts. The series features pressure balanced single seated plug, balance seal ring and high leakage level, with standard leakage level IV and V for optional. Also the series has small unbalanced force, which can effectively overcome the resistant force of the fluid; therefore smaller actuators can be configured to achieve higher shut-off differential pressure.
TGD (B) Series Balanced Three Way Diverting Control Valve

TGD (B) Series Balanced Three Way Diverting Control Valve

Traditional three way control valves usually possess unbalanced trim types, the bigger the body size, the higher the unbalanced force, therefore the lower the allowable differential pressure. When large diameter merging and diverting universal three way control valves are adopted in diverting conditions, the plug is easy to oscillate and unstable when it is close to the seat. TGD Series Balanced Three Way Diverting Control Valve, featuring balance seal ring structure, low unbalanced force, high allowable shut-off pressure, stable performance and high leakage level, is able to meet the requirements of large diameter and high differential pressure three way control valves in extra-large devices.
ER Series Rotary Eccentric Plug Control Valve

ER Series Rotary Eccentric Plug Control Valve

Eccentric Rotary Control Valve, a.k.a. Camflex Valve features novel structure and small flow resistance. The disc rotation center is eccentric to the rotation axis, which can reduce seat wear and prolong life span. The small pressure drop can avoid cavitation as well as reduce noise and vibration.
BV Series V-Ported Control Ball Valve

BV Series V-Ported Control Ball Valve

V-Ported Control Ball Valve features small size, light weight, high flow capacity and wide adjustable range. The unique V-Ported cut on the plug forms a fan-shaped area with the seat, in the opening and closing process, the purpose of medium flow adjusting is achieved by changing the flow cross-sectional area, the flow characteristics is approximately equal percentage. During the operation the plug is always stick to the seat to produce a scratch effect to prevent dirt from adhering to the fan-shaped area, the V-Ported cut has sharp edges to easily cut fiber medium, which makes it suitable for medium containing fiber, fine particles, slurry and so on.
