Engineered for precision and reliability, these critical components ensure optimal flow management and system safety across various industries. Featuring advanced functionalities, they are designed to meticulously regulate, control, or stop the flow of liquids, gases, or slurries in diverse systems. Their robust design focuses on maintaining operational efficiency by providing dependable performance in demanding applications.
Valves are critical components for controlling the flow of liquids or gases in systems, ensuring precise regulation and operational efficiency. Choosing high-quality valves is essential to maintain safety, prevent leaks, and optimize performance in industrial or residential applications.
Valves are widely used in HVAC systems, plumbing, automotive engines, and manufacturing processes. They are ideal for scenarios requiring reliable flow control, pressure adjustment, or directional changes in fluid or gas systems.
When selecting valves, consider factors like material compatibility (e.g., stainless steel for corrosive environments), valve type (ball, gate, or globe), and size to match your system's requirements. Prioritize durability and ease of maintenance for long-term reliability.
1. Classified by role and use;
(1) cut-off valve: cut-off valve is also known as closed circuit valve, stop valve, its role is;
(2) check valve: check valve is also known as a one-way valve or check valve, its role is;
(3) safety valve: the role of the safety valve class is to prevent the pipeline or device in;
(4) regulating valves: regulating valve category including regulating valves, throttling valves and pressure reducing valves;
(5) Diverter valves: diverter valves include a variety of distribution valves and traps, etc., ;
(6) Exhaust valves: Exhaust valves are essential auxiliary elements in piping systems;
2. Classified by nominal pressure;
(1) Types of valves
1. Classified by role and use
(1) cut-off valve: cut-off valve is also known as closed circuit valve, shut-off valve, its role is to connect or cut off the medium in the pipeline. Cut-off valve types include gate valves, globe valves, plug valves, ball valves, butterfly valves and diaphragm valves, etc.
(2) Check valve: check valve is also known as one-way valve or check valve, its role is to prevent the backflow of media in the pipeline. Its main role is to prevent the backflow of the medium, to prevent the pump and drive motor reversal, as well as the release of the container medium. Water pump suction off the bottom valve also belongs to the check valve category.
(3) Safety valves: the role of safety valves is to prevent the pipeline or device in the medium pressure exceeds the specified value, so as to achieve the purpose of safety protection.
(4) Regulating valves: regulating valves include regulating valves, throttling valves and pressure reducing valves, whose role is to regulate the pressure of the medium, flow and other parameters.
(5) Diverter valves: Diverter valves include a variety of distribution valves and traps, etc., whose role is to distribute, separate or mix the media in the pipeline.
(6) Exhaust valves: Exhaust valves are essential auxiliary components in piping systems and are widely used in boilers, air conditioning, oil and gas, and water supply and drainage pipelines. They are often installed at high points or elbows to remove excess gas from the pipeline, improve the efficiency of the pipeline and reduce energy consumption.
2. Classified by nominal pressure
(1) Vacuum valve: refers to the valve whose working pressure is lower than the standard atmospheric pressure.
(2) Low pressure valve: refers to the nominal pressure PN ≤ 1.6Mpa valve.
(3) Medium pressure valve: refers to the nominal pressure PN 2.5, 4.0, 6.4Mpa valve.
(4) High pressure valve: refers to the valve with a nominal pressure PN of 10~80Mpa.
(5) ultra-high pressure valve: refers to the nominal pressure PN ≥ 100Mpa valve.
3. classified by working temperature
(1) ultra-low temperature valve: for the medium working temperature t<-100 ℃ valve.
(2) low-temperature valve: for the medium working temperature -100 ℃ ≤ t ≤ -29 ℃ valve.
(3) room temperature valve: for medium working temperature -29℃
(4) medium temperature valve: for the medium working temperature 120 ℃ ≤ t ≤ 425 ℃ valve.
(5) high temperature valve: for the medium working temperature t>450℃ valve.
