About The Butterfly Valve Electric Actuator

Date:Jan 31, 2019

With the development of electric valves, there are many well-known companies at home and abroad. Nowadays, electric butterfly valves are more and more widely used in practical applications. The products are favored by customers with excellent quality and perfect after-sales service. The connection methods mainly include: flange type and clamp type. Electric butterfly valve is a kind of electric valve and electric regulating valve. Electric butterfly valve sealing form mainly include: rubber seal and metal seal. The electric butterfly valve controls the switching of the butterfly valve through the power signal. This product can be used as shut-off valves, control valves and check valves of piping systems. With manual control device, once a power failure occurs, manual operation can be performed temporarily without affecting the use. Electric butterfly valve is the perfect combination of electric actuator and butterfly valve. The same required torque configuration complies with the internationally accepted SIO5211 connection standard platform and mutual fine adjustment of ±5° to achieve precise convergence. 

Actuators:electric actuators 90 ° 120 ° 180 ° 270 ° rotation angle stroke torque control is divided into switched passive contact feedback type, intelligent adjustment type, and special environment explosion-proof, flameproof type. Hard aluminum alloy shell, DC24v, AC220v, AC380v, etc. can be selected for power supply. Built in overheat protection, central control feedback signal, indicator perspective window, and in passing emergency power manual device with power failure. Protection class IP67. The bottom mounting dimensions conform to ISO5211/DIN3337 international standards. Adapt to the ambient temperature of 8 °C, epoxy resin coating. Detailed data provided by the supplier separately. 

The advantages of electric butterfly valve
1. it is convenient and quick to open and close, labor saving, with low fluid resistance, and can be operated frequently.
2. simple structure, small size, light weight.
3. can transport mud, the minimum amount of liquid accumulated in the pipeline mouth.
4. under low pressure, good sealing can be achieved.
5. good regulation performance.

The disadvantages of stainless steel butterfly valve
1. small operating pressure and working temperature range.
2. poor sealing.
