The bidirectional district heating butterfly valve is specially designed for district heating and district cooling applications. The SV fully metal seated butterfly valve is widely used to meet the demand of on-off and regulating in thermal power plant, the heat exchange station, regional boiler room, the hot water pipe network
1.Designed with bidirectional sealing structure,the installation of the bidirectional rotary ball valve will not be restricted by the direction of the fluid.
2.Since the metal sealed bidirectional rotary ball valve is offered with self-sealing device,reliable sealing performance can be realized under the pressure from medium.
3.Powerful specific pressure of sealing can be obtained the valve is installed on the direction in opposite to that of the fluid.The pressure acts on the valve seat of the bidirectional rotary ball valve. The contact area of the point action is annular,
4.The rotary ball valve has long service life due to wear compensation.
5.The unique rotational structure ,as well as the sphere-conical sealing surface of the valve seat,makes for the cleaning function the solid particle will be crushed when the electric operated bidirectional rotary ball valve is opened or closed.
