Electric butterfly valve automatic control

by:Sino Valves     2021-02-25
The valve electric butterfly valve adopts automatic control function. In the remote automatic control mode, the actuator calculates the valve position value desired by the user according to the control current. The AC220 single-phase AC power supply is used as the driving power source, and it accepts operations from the DCS, PLC system or adjustment instrument. The full electronic actuator with DC4~20mA, DC0~10mA or DC1~5V control signal of the actuator, the actuator has the function of action switching, opening signal function and manual function. Electric butterfly valve, hydraulic butterfly valve, butterfly valve with lock, specializing in the production of various butterfly valves, non-standard customization, can be customized according to customer needs. Butterfly valve with lock, factory direct sales, soft seal electric butterfly valve, affordable, welcome to inquire, specialize in manufacturing with lock Butterfly valve manufacturer: The company has more than 10 years of history as an electric valve manufacturer. Its products include electric butterfly valves, electric ball valves, electric gate valves and electric actuators. The electric/pneumatic valves (butterfly valves, ball valves, gate valves, actuators) provided meet strict requirements.

It is a three-dimensional eccentric principle design, which makes the space motion trajectory of the sealing surface idealized. There is no friction and interference between the sealing surfaces, and the sealing material is selected appropriately, so that the butterfly valve has the sealing performance, corrosion resistance, high temperature resistance and resistance. The grindability has been reliably guaranteed. Its main features are as follows: 1. Small opening torque, flexible and convenient, labor-saving and energy-saving. 2. The three-dimensional braided core structure makes the butterfly plate tighter and tighter, and its sealing performance is reliable and leak-free. 3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc. Product features: ★Short switching time, 4 seconds to complete the switching action. ★The allowable pressure difference is large. ★With self-cleaning function, it can effectively ensure the smooth flow of pipeline. ★Good sealing performance. ★Long life, adopting electric quick-opening actuator (actuator) to drive new technology: only use electric energy when working. Zero power consumption when idle. Meet the environmental protection design requirements. ★ Wide adaptability. Various connection options (flange, wafer type, etc.) ★Straight-through structure is simple and reliable, and maintenance-free design. The superior process performance makes the products widely used in various industrial fields. Such as: industrial boilers, water supply, pipeline media cutting, pipeline transportation, etc. Electric wafer butterfly valve, sealed and zero leakage. The control is precise and sensitive, and it is available from stock! Buy electric wafer butterfly valves, to the valve, excellent quality! Electric butterfly valves are an important executive unit in the field of industrial automation control. Electric butterfly valves are driven by angular stroke electric actuators (0~90°partial rotation) It is mechanically connected to the butterfly valve as a whole, and is composed after installation and debugging. Input 220V power supply pressure to drive the disc plate to rotate 90 degrees to achieve the opening and closing effect, and also input the control signal 4~20m signal to adjust and control the pipeline medium flow. It is widely used in many fields, soft sealing wafer butterfly valve, handle wafer butterfly valve, valve specializing in the production of electro-pneumatic butterfly valve, advanced technology, high equipment, low price, soft sealing gate valve, standard purchase, strict quality, high quality, right Clip-on butterfly valve, durable, cost-effective, production technology, production equipment.. Excellent quality, zero leakage, accurate electric control, full models. . Integrity service, excellent quality! Electric butterfly valve, pneumatic butterfly valve, is the choice of our customers, professional production, sophisticated products, stainless steel electric butterfly valve, with strong two-way functionality, valve after-sales service has won the trust of customers, the product has two-way sealing function, Strong airtightness, perfect after-sales service.. ◆ No opening cover debugging, working parameter setting, switch limit debugging can be completed by operating the knob, no need to open the electrical cover, so that harmful substances such as dust and moisture in the environment cannot enter the actuator Internally, the reliability of the electrical control part is greatly improved. ◆ High intelligence has the function of man-machine dialogue, and the electrical control part adopts a new SOC chip control, which is highly intelligent. ◆Protective aluminum alloy shell and box body have strong anti-corrosion ability after surface phosphate treatment. The box body with O-ring at static fit and skeleton oil seal at dynamic fit reaches IP68 protection level, optional Explosion-proof box can be suitable for IIA, IIB level T1-T4 level explosive mixtures 1, 2 areas and other hazardous working environments. ◆ High-efficiency, low-noise precision worm gear reduction mechanism, small clearance, high efficiency, low noise (up to 50 decibels), and long life. ◆ Self-locking The self-locking of the worm gear and the worm prevents the reversal phenomenon of the actuator in the case of power failure or signal failure. ◆ Liquid crystal display The liquid crystal screen digitally displays the valve opening size in real time, and displays alarm information in real time according to the working conditions; the high-brightness LED light-emitting tube indicates the valve opening and closing limit position. ◆ Control mode: Remote switch signal can be controlled (optional remote 4∽20mA current signal control), and the position of the valve can be adjusted on-site by operating the knob on site. ◆ The status indication uses the relay contact output to indicate the valve's switch limit and fault alarm (4∽20mA current signal output can be selected to reflect the valve opening).
