Valves are plumbing accessories used to open and close a pipe, control flow direction, regulate and control parameters of the transport medium (temperature, pressure and flow). According to their function, they can be classified into shut-off valves, check valves, regulating valves, and the like.

The valve is a control part in a fluid conveying system and has the functions of stopping, adjusting, guiding, preventing counter flow, stabilizing pressure, shunting or overflowing and relieving pressure and the like. Valves used in fluid control systems range in variety and size from the simplest shut-off valves to the variety of valves used in extremely complex autonomous systems.

The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The valves are further classified into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome molybdenum steel valves, chrome molybdenum vanadium steel valves, dual-phase steel valves, plastic valves, nonstandard valves, etc. according to the material.

Under winter low temperature environment, because the difference in temperature is big round the clock, water in the valve water pipe can be frozen at night and condense, in the noon after the temperature rise, can melt to can repeat this process many times, under the effect of continuous expend with heat and contract with cold, very easily lead to the valve impaired, especially the valve that can the simultaneous control hot and cold water, after melting to freeze, when releasing hot water, can cause very big difference in temperature, the damage of valve with higher speed, when serious, can lead to the direct spalling of valve even.
