Motorized Butterfly Valve

Motorized Butterfly Valve

Motorized butterfly valve consists of CHR angle-stroke electric actuator and straight-through casting butterfly valve body. The electric actuator has strong function, small volume, light and cheap, reliable performance and simple supporting. The electric switch butterfly valve body has large circulation capacity, for normal temperature and clean media, the valve plate with soft seal (rubber ring, teflon ring) can be selected to reduce leakage (up to zero leakage), high temperature and high pressure conditions can be selected from three eccentric hard seal structure, using a "U" type stainless steel sealing ring, the precision resilient seal ring and polished butterfly plate three-dimensional eccentric contact with the polished butterfly plate. It solves the traditional eccentric butterfly valve in the opening and closing 0°~ 10°instant sealing surface is still in the sliding contact friction, to achieve the butterfly plate in the opening instant sealing surface is separated, closed contact is sealed, to achieve the purpose of extending the service life, sealing performance is good.

The electric butterfly valve is suitable for the occasion that needs flow regulation. Since the pressure loss of butterfly valve in the pipeline is relatively large, about three times that of gate valve, therefore, when choosing butterfly valve, the influence of pressure loss on pipeline system should be fully considered, and the sturdiness of butterfly plate to bear the pressure of pipeline medium when closing should also be considered. In addition, it is also necessary to consider the limits of the working temperature that the resilient valve seat material can withstand at high temperatures. Butterfly valve structure length and overall height is small, open and close fast, and has good fluid control characteristics, butterfly valve structure principle is most suitable for making large diameter valves. When butterfly valves are required for flow control use, the most important thing is to select the correct size and type of butterfly valve so that it can work properly and effectively.

Advantages of electric butterfly valve produced byZhejiang Huachi Valve Co., LTD：

1、Electric butterfly valve is convenient to open and close quickly, save energy, small fluid resistance, and can be operated frequently.

2、Electric butterfly valve has simple structure, small volume and light weight.

3、Electric butterfly valve can transport slurry and accumulate the least liquid at the mouth of the pipeline.

4、Electric butterfly valve can achieve good sealing under low pressure.

5、Electric butterfly valve has good adjustment performance.
