Motorized Butterfly Valve


Description of Motorized Butterfly Valve:

ZECO motorized butterfly valve is suitable for the occasion of flow regulation. Because the butterfly valve disc and stem components still have the problem of resisting medium flow in the pipeline, the pressure loss of butterfly valve is still greater than that of gate valve. Therefore, the influence of pressure loss should be considered when selecting motorized butterfly valve as the regulating or switching valve. But the structure of the butterfly valve length is short, the overall height will be short many compared to other valves, at the same time open speed by electric, gear or handle faster than many other valve operation, at the same time has good flow control characteristics, so the use of motorized butterfly valve range is very wide, usually as the regulation of motorized valves and motorized switch valve is used in petroleum, chemical industry, power plants, pharmaceutical, shipbuilding, metallurgy and other industrial areas, at the same time as the pipeline system of cut-off valve, control valve and check valve. ZECO, as a professional manufacturer of motorized butterfly valves, usually uses specially designed metal sealed triple eccentric or double eccentric butterfly valves as recommended products for users under special working conditions.


Features of Motorized Butterfly Valve:

1. The mounting pad of ZECO motorized butterfly valve is designed as per ISO 5211. It is easy for the user to configure the standard electric actuator by himself or directly by ZECO's fully configured electric actuator delivery;

2. The upper and lower stem of ZECO motorized butterfly valve is designed in anti blow out. This design prevents the risk of blow out when maintenance is required;

3. The seal of ZECO motorized butterfly valve is designed in fire safe. Sealing is not resilient seated and can meet API 607 fire test requirements;

4. The torque of ZECO motorized butterfly valve is low. Users can match a lower gear than the conventional electric actuator, saving costs.
