Shanghai Rong Titanium Valve Manufacturing Co., Ltd. is the electric control valve} {ZDRWG professional manufacturers. The quality of survival, integrity and development, has a collection of scientific research, design, manufacture, sales and service in one of the high-quality workforce, strong technical force, advanced production technology. Sophisticated processing equipment, sound detection equipment, a sound quality assurance system to ensure product quality and reliability. Product description ZDRWG electrically adjustable electrically adjustable butterfly valve to 220V AC power supply for power, accept 0 ~ 10mA or 4 ~ 20mA standard signal, driving the valve opening signal corresponding with this operation, to regulate the media pressure, flow, temperature of the purpose, structure simple and easy to operate. Off valve plate oblique oval structure, a small amount of leakage. For large diameter, high flow applications. Because self-cleaning effect, it is particularly suitable for ventilation systems and conditioning medium containing suspended particles. The butterfly valve with electric actuator supporting the use of energy for the metallurgical, power, petrochemical, light imitation, building materials, environmental protection and industrial piping in a variety of liquids, gases, dust and gas, smoke and other media through various control signals to change the size of the flow, thus industrial process automatic adjustment and remote control.
