Electric trunnion mounted 2pc ball valve WCB

Electric Trunnion Mounted 2pc Ball Valve

The valve and the actuator are connected in a direct way. The electric actuator is equipped with a built-in servo system. No additional servo amplifier is required. The operation can be controlled by inputting 4-20mA signal and 220VAC power supply. The utility model has the advantages of simple connection, compact structure, small size, light weight, small resistance, stable and reliable action, etc. The actuator can be equipped with electronic electric actuators such as UNIC, PSQ, HQ, DHL or pneumatic piston actuators such as GTX, AL according to user requirements.

Structure and purpose editing and broadcasting
Electric Trunnion Mounted 2pc Ball Valve, also known as the measuring and assembling split ball valves, divide the valve body into two asymmetrical left and right halves along the section perpendicular to the axis of the valve passage, which are mainly used to cut off, distribute and change the flow direction of the medium on the pipeline. Its pivot structure ensures accurate ball position. The standard valve seat adopts spring structure to push the valve cover to the ball, ensuring good low pressure sealing performance. The front and back valve seats of the ball valve can be sealed, which is the so-called two-way sealing feature. With the built-in drain valve, the middle chamber of the valve body can be discharged outward. The pivot shaft adopts anti blow out protection structure, low friction coefficient bearing, etc. The utility model has the advantages of excellent performance, high reliability, wide use, reasonable price, etc.
Electric Trunnion Mounted 2pc Ball Valve is applicable to chemical, petroleum, natural gas, metallurgy, and other industries, as well as long-distance natural gas transmission pipelines with hydrogen sulfide medium, many impurities, and serious corrosion.
