Hart Control Valve Positioner Explosion Proof Exia Single Acting Fail Lock C45FY-LSB
Smart valve positioner, intrinsically safe explosion-proof Exia, straight stroke, single acting, fail lock, stainless steel corrosion-resistant
Standard mounting bracket A for straight travel and standard bracket B for angular travel are suitable for most valve actuator installation needs; if the actuator is of special structure, TORLEO can provide customized mounting brackets. New installation or re-installation, the positioner needs to be self-tuning.
Product application field
TORLEO brand TOP-5879F1 series smart valve positioner are used in conjunction with pneumatic control valves, and are widely used in metallurgy, power generation, paper-making, environmental protection and other industries where process control is required.
Typical valve application
Diaphragm control valve, single-acting ball valve, single-acting butterfly valve
