Product Introduction:

D942X Electric Bi-directional Double Eccentric Flange Butterfly Valve.

This large-size electric butterfly valve adopts bi-directional double eccentric soft sealing structure. 

Equipped with high-torque electric actuator with manual override.It achieves tight shutoff under forward and reverse pressure, flow direction free installation. 

Integrated support legs reduce pipeline load, specially designed for ultra-large diameter main pipelines.Suitable for water conservancy pumping stations, municipal main water supply pipelines, wastewater treatment plants. Supports remote PLC control for automatic water system.

Application:

Large-scale water pumping stations.

Urban water supply trunk lines.

Sewage treatment plant inlet and outlet mains.

Regulating reservoir pipelines.

Centralized heating circulating water systems.

Large industrial park water supply systems.

Tunnel water supply and drainage networks.

Smart water automation projects.

Selection Guidelines: 

1. For pipelines under bidirectional pressure, with variable flow direction, and water hammer conditions, the D942X bidirectional pressure butterfly valve is the preferred choice.

2. For unidirectional water flow and general water supply and drainage projects, the D943X electric unidirectional double eccentric butterfly valve can be selected.

3. For small-diameter pipelines requiring manual on-site operation, the manual D342X model is recommended; for remote automatic control, the D942X model is recommended.
