Electric device description

DZW multi turn valve electric device, also known as multi turn electric actuator, multi turn electric actuator, and multi turn electric device abbreviated as Z-type electric device, is a driving device for opening, closing, or regulating control of valves and similar equipment. Z-type electric actuators are widely used in industries such as power, metallurgy, petroleum, chemical, papermaking, and wastewater treatment. Multi turn electric actuators are suitable for multi turn valves and similar equipment such as gate valves, globe valves, diaphragm valves, plunger valves, water gates, throttle valves, etc. If supported, they can be used as straight stroke electric actuators and can be used for opening and closing machines. If equipped with a secondary reduction device, they can be used for partially rotary valves such as butterfly valves, ball valves, etc. If supported, they can be used as angular stroke electric actuators such as flap doors, baffle doors, air doors, etc.

Yangzhou Beier Valve Control Co., Ltd. is an established enterprise in the industry, specializing in the research and development, design, production, and sales of "Beier" brand electric actuators.

Valves play an important role in cutting off and throttling the medium in the pipeline they are located in. As an extremely important cut-off valve, globe valves seal by applying torque to the valve stem, which exerts pressure on the valve disc in the axial direction, making the sealing surface of the valve disc tightly fit the sealing surface of the valve seat, preventing the medium from leaking along the gaps between the sealing surfaces.

The sealing pair of the globe valve consists of the sealing surface of the valve disc and the sealing surface of the valve seat. The valve stem drives the valve disc to move vertically along the centerline of the valve seat. The opening height of the globe valve is relatively small during the opening and closing process, making it easy to adjust the flow rate, and easy to manufacture and maintain, with a wide range of pressure applications.
