The disc of the butterfly valve is that the disc has a shaft rotating on the position of the valve seat. The angle of the rotation determines the opening and closing degree of the valve. The following is the main topic: how to select the electric butterfly valve correctly. 1. Stem diameter One situation is the multi-turn type rising stem valve, which cannot be installed on the electric valve. Therefore, when purc

Working principle of electric butterfly valve: The working power supply usually includes: AC220V, AC380V, etc. Input signal: 4~20mA 0~10v and other weak current signals. After the adjustment type electric actuator and the valve stem are connected and debugged, the electric energy is used as the driving force to drive the hard-sealed butterfly valve plate for a 0-90° partial rotation. Receive the 4-20mA signal of

Electric butterfly valves belong to a variety of electric valves and electric regulating valves. Electric butterfly valve connection methods mainly include: flange type and wafer type; electric butterfly valve sealing forms mainly include: rubber seal and metal seal. The electric butterfly valve controls the switch of the butterfly valve through the power signal. The product can be used as a shut-off valve, control v

While valves are probably a small part of your piping manner or gadget in phrases of area, they’re regularly a significant part of the layout and construct budget. They have a widespread effect on long-time period prices and standard gadget performance. The first issue to remember is the general length of the valve -- each in phrases of bodily dimensions and phrases of inner length and glide rates (CV). C

According to the characteristics of butterfly valve, the following principles should be followed when selecting butterfly valves: ① Compared with gate valves, globe valves, ball valves, plug valves, etc., butterfly valves have the smallest structural size, lightest weight, and low price. Therefore, for large-size pipelines, replacing other shut-off valves with butterfly valves is very beneficial to reduce the constr

The butterfly valve has 90. Features such as rapid opening and closing of rotation, light weight, small structure size (especially wafer butterfly valve) and other advantages. However, its sealing reliability is relatively poor, so it is often used in medium and low pressure and medium and low temperature conditions in industrial production equipment. With the large-scale petrochemical production equipment, it is a
