Highlight: Lift Check Valve
Product introduction:
Check valve is also known as back-pressure valve or non-return valve. Check valve is only to allow the medium to flow in one direction, and prevent reverse flow.Usually the valve operates automatically, with the disc opening under pressure of a fluid flowing in one direction;When the fluid flows in the opposite direction, the self-coincidence disc of the fluid pressure and the disc acts on the seat, thus cutting off the flow.
Lift check valve disc along the vertical center line of the valve body slide check valve, its structure is similar to the globe valve, valve body and disc same as the globe valve.The upper part of the valve and the lower part of the valve cover processing guide sleeve, the valve can be free lifting in the guide cylinder, when the medium downstream, the valve disc by the medium thrust open, when the medium stop flow, the valve disc by vertical landing on the seat, prevent the medium counter-flow effect.This kind of valve is widely used in chemical industry, metallurgy, pharmaceutical and other fields, should be installed horizontally in the pipeline.

Product features:
1. check valve must be installed and used, that is medium flows in the direction of the arrow shown.
2. Its small volume, light weight, good processing technology, is one of the development direction of check valve, but the fluid resistance coefficient is slightly larger than swing check valves.
3. When the medium flows in the specified direction, the valve disc is subject to the action of the medium force, when the medium counter flow is opened, due to the weight of the valve disc and the valve disc is subject to the action of the medium reverse force, so that the sealing surface of the valve disc and the valve seat is closed, to prevent the medium flow-back purpose.
4. The sealing surface of valve body and disc is overlaying with stainless steel
