Explosion Proof Ball Valve with Positioner are mainly used in petrochemical, metallurgy, light industry and other industrial automation fields to cut off or circulate medium in gas and liquid pipelines. It has the advantages of simple structure, fast switching, large circulation capacity and zero leakage.
The explosion-proof electric actuator is made of a stainless steel body with reinforced PTFE seats and seals for a long service life. It can be supplied in two-position (open and closed) or modulating control for throttling applications. The WE Series is weatherproof and CSA approved, Type 4 and 4X; torques 350 – 80,000 in-lb. The XE Series is explosion-proof and ATEX/IECEx Certified Ex d IIB T4 Gb, IP67; torques 500 – 25,900 in-lb.
A valve positioner is a control valve accessory that sends a pneumatic signal, usually a 4-20mA input, to the actuator to adjust its position so that it matches the set point from the control system. It can be used for both linear and rotary actuators, is available in class 1, div 1 versions and offers internal servo operation, opening signal position feedback, position indication and easy connection.
