Ball / segmented

A trunnion mounted segment rotary control valve with spring-loaded metal seats, the R-Series has a one-piece body that eliminates the effects of piping forces and the risk of joint leakage. The segment itself is contoured to give optimum flow characteristics along with high rangeability and very high flow capacity.

Q-Trim valves optimize noise attenuation and cavitation, pass impurities, provide very high rangeability and keep the valve dimensions, weight and cost reasonable. Q-Trim valves generally attenuate noise by up to 30dBA, compared to standard trim valves, and vibration levels by more than 90%.

The unit consists of a reliable segment ball valve, complete with a high-resolution step-motor-driven rotary actuator, limit switches, and potentiometer. This combination makes it possible to attain up to 28200 discrete repeatable positions through a 90 degree operation range to compensate for fluctuations in stock flow.
