LNG butterfly valves

LNG butterfly valve, also called the flap valve is mainly composed of valve body, valve stem, disc and seal ring. The body is cylindrical, short axial length, built-in butterfly plate. Can be used for low pressure pipeline LNG switch control. On the LNG pipeline mainly cut off and throttling effect. Butterfly valve opening and closing is a disc-shaped butterfly plate, the body rotation around its own axis, so as to achieve the aim of opening and closing or adjust. Butterfly plate by the stem drive, if turned 90 & deg; Can complete an opening and closing, can change the butterfly plate deflection Angle control medium flow. Common butterfly valve applies to the generator, gas, natural gas, liquefied petroleum gas, city gas, cold hot air smelting, chemical industry and power generation, environmental protection, such as, building water supply and drainage engineering system in conveying all kinds of corrosive fluid pipe, non corrosive, used to adjust and block the flow of the medium.

LNG ball valve

LNG ball valve installed in the valve body ball, ball by stem, and around the rotation of the ball valve axis, adjust and control can be used for LNG. Among them, hard seal v-shaped ball valve the v-shaped ball core of carbide surfacing with strong shear force between metal valve seat, especially suitable for fiber, tiny solid material, such as medium. And ball valve in the pipeline is not only more connected to the confluence of flexible control medium, shunt, and the flow switch, at the same time also can close any channel and make the other two. This Industrial Valves shall generally be installed in the pipeline. Drive mode divided into pneumatic ball Industrial Valves and ball valve in accordance with the manual ball valve.
