Guangdong Electric Butterfly D971

 (English: Electronic Butterfly Valve) connections are: flange and wafer type. Device Control is an important field of industrial execution unit. Well-known domestic manufacturers have? Dongguan Hong Valve Valve Co., Ltd. is a company specializing in valve actuators, compact pneumatic valves, electric valves, manual valves, UPVC electric valves and other structure, beautiful appearance, stable performance, high reliability, low noise, intelligent control, easy to use features. The main products are: electric valve actuators, pneumatic actuators, pneumatic valves, electric valves, manual valves, UPVC valve, electric valve, manual valve, electric butterfly valve, manual valve, pneumatic valve, pneumatic valve, manual valve, electric valve. Its products in the industry have a certain price advantage and technical advantage of this valve is usually installed horizontally. Structure and principle electric butterfly valve usually integrally connected by a rotary electric actuator (0 ~ 90 ° part-turn) through the flange, after the installation of common components. Classification according to the operation modes: switching and modulating. Switching is directly connected to the power (AC220V or other power supply level) by switching positive, ABM always complete the switching operation. Smart is AC220V power as power, industrial automation and control system receives the default parameter values ??4 ~ 20mA (0 ~ 5, such as weak control) signal to adjust the action is completed. Electric Butterfly main purpose is widely used in building automation \ Power \ Petrochemical \ drainage works \ cooling water automatic control system \ Automatic temperature control system \ paper industry automation and control equipment with various types of basic characteristics of an electric valve, electric butterfly valve has a simple structure, small size, light weight, material consumption province, small installation size, switch quickly, 90 ° reciprocating rotary drive torque characteristics of small, used to cut, turn, adjust the line of medium, having good fluid control features and Close sealing performance. 2, the electric valve can carry mud accumulation of fluid in the pipe mouth least. Under low pressure, a good seal can be achieved. Regulation performance. 3, streamline design electric butterfly valve disc and the fluid resistance loss, it can be described as a kind of energy-saving products. 4, the electric valve stem through-rod structure, after quenching, with good mechanical properties and corrosion resistance, abrasion resistance. When the electric valve opening and closing the valve stem rotates not only for the lifting operation, the valve stem packing is not easy to destroy, reliable sealing. And disc taper pin fixed, extended end to prevent out design, in order to avoid the stem and disc connected to the valve stem when the collapse of the accident at the break. 5, electric butterfly valve connections are flanged, wafer, welded connections and lug wafer connection. Drive the form of a manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic actuator linkage, enabling remote control and automation. Advantages of electric butterfly valve 1, the electric valve open and close easily and quickly, saving, fluid resistance, can often operate. 2, the electric valve of simple structure, small size and light weight. 3, the electric valve can carry mud accumulation of fluid in the pipe mouth least. 4, electric butterfly valve under low pressure, can achieve a good seal. 5, the electric valve regulated performance.
