Multi Single Disc Door flanged swing type check valve drain valve CE certificate

The globe valve is composed of a valve body, a valve cover, a valve cover gasket, a valve stem, etc. According to the direction of the channel, the globe valve is divided into four types: straight-through globe valve, direct-flow globe valve, Angle globe valve and plunger globe valve, which are widely used in chemical, pharmaceutical, light industry, paper making, metallurgy, textile, natural gas, municipal engineering, food, ships, electric power and other industries. The parent metal of the globe valve disc is A42AP material, and the surfacing sealing surface is made of TIG welding and cobalt-chrome-tungsten-hard alloy welding wire. The working principle is to rotate the handwheel, so that the threaded guide sleeve rotates, and the anti-rotating block limits the rotation of the valve stem, so the rotating movement of the handwheel is transformed into the straight up and down movement of the valve stem; Relying on the stem pressure, the sealing surface of the valve disc and the sealing surface of the seat are closely fitted to prevent the flow of the medium.
