Products Detail

Specification of this China Supplier Integral explosion proof electric actuator
Actuators with Integral controls are supplied ready for use with local control, operating and switching elements. The direct processing of the actuator signals on site enables the transfer of simple process control functions to the field level. The integral explosion proof electric actuator is one upgrade quarter turn valve electric actuator of QB part turn electric actuator, which is used normally equipped with 90° turn valves, such as central lined butterfly valve or ball valve. It is die-casting aluminum, which features with small size, light weight, high efficiency, high reliability, high protection class and multi control types. It can be operated on site by manual or electric and remote control. QBR explosion proof quarter turn electric actuator is used widely in the field of petroleum, chemical, metallurgy, power plant and water treatment. QBR integral explosion proof electric actuator can be produced according to standard type, integral type, explosion proof type, explosion proof integral type and integral regulating type. Its protection class is normally IP67, and explosion class ExdIIBT4.
