Gate valve and butterfly valve which is installed when there is a direction?
There is no direction when installing the valve. The butterfly valve has an eccentric butterfly valve which is in the direction of installation
Do not require frequent opening and closing, and keep gate fully open or fully closed. Not suitable for use as a regulator or throttling.
Do not require frequent opening and closing, and keep gate fully open or fully closed. Not suitable for use as a regulator or throttling.Butterfly valve refers to the closure of parts (butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually 90 degrees butterfly simple structure, small volume and light weight, only by a few parts. Moreover, the utility model can be rapidly opened and closed only by rotating 90 DEG, and the operation is simple.Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, gate valve advantages: fluid resistance is small, opening and closing more effort, medium flow unrestricted, not disturbing flow, do not reduce pressure.
