The Q9B41F/Q9B41H explosion-proof electric flange ball valve is composed of a ball valve and a 3410 electric actuator. It is driven by a 220V AC single-phase power supply and receives 4-20mADC or 1-5VDC input signals from a computer regulator or operator to operate. The explosion-proof level is ExdIIBT4 and can also be used as ExdIICT6. The sealing ring of the sphere adopts special processing technology and the latest sealing materials, which make the surface roughness and roundness of the sphere meet the standard requirements, thereby improving the sealing performance, service life, and high-temperature resistance. The timing plate moves the handle to drive the valve stem to rotate the ball, allowing the medium to pass smoothly.
Application scope
Industrial automatic control systems widely used in industries such as food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and research equipment and power.
