1. General purpose valve: A general term for valves with a wide range of applications, also known as ordinary valves. It is not a valve designed for specific conditions and purposes.
Although there is no clear definition for universal valves, they mainly refer to manually operated globe valves, gate valves, check valves, butterfly valves, and ball valves with pressures below 2MPa. Valve housing materials mainly include gray cast iron, ductile iron, malleable cast iron, carbon steel, stainless steel, and bronze.
2. Cast iron valve: A valve made of cast iron for the valve body and cover material of the pressure bearing shell.
3. Cast steel valve: A valve made of carbon steel and low-alloy steel castings for the valve body and cover material of the pressure bearing shell.
4. Stainless steel valve: A valve made of stainless steel for the valve body and cover material of the pressure bearing shell.
5. Bronze valve: A valve made of bronze for the valve body and cover material of the pressure bearing shell. Bronze valves are mostly flange and threaded valves with nominal pressure below 20K and nominal diameter below 100.
6. Brass valve: The valve body and cover material of the pressure bearing shell are made of brass. Brass valves are valves with relatively small diameters that are stocked, cast, and forged.
7. Forged valve: A valve whose body and cover are formed using free forging or die forging processes. Forged valves generally use materials such as brass, carbon steel, alloy steel, stainless steel, etc., and are mostly valves with relatively small diameters.
8. Plastic valve: also known as a plastic valve. It is a valve made of materials such as rigid polyethylene and chlorinated polyvinyl chloride. Although this valve has excellent corrosion resistance, it is only suitable for use under normal temperature and low pressure conditions.
9. Ceramic valve: The main components are valves made of ceramics. It has good corrosion resistance and wear resistance, but the impact of mechanical and thermal shock on this valve needs to be considered during use.
Faucet: A component installed at the end of water supply and hot water pipelines in building and waterway facilities to control the flow of water.
Valves usually manufacture both the inlet and outlet ends as pressure bearing components, but most faucets only need to manufacture the inlet end as a pressure bearing component, while the outlet end exposed to air is manufactured as a non pressure bearing component.
JIS B2061: 2006 (Faucet) mainly targets single handle faucets, mixed hot and cold water faucets, water stop plugs, float valves, as well as toilet flush valves and faucets.
Huadian CNC specializes in producing valve processing machine tools, valve processing special machines, and valve processing equipment, which are used for turning and drilling of forged steel, cast steel (carbon steel) gate valves, globe valves, butterfly valves, etc. The cutting amount reaches 10mm, which is efficient, convenient, stable, and reliable.
11. Stop cock (stop valve): It is a plug installed in the water supply pipeline to cut off the flow of water.
12. Snap tap (ferule): A faucet used when branching off a water supply pipeline.
13. Cock: A general term for equipment that contains a rotatable plug inside a conical or cylindrical valve body to cut off the medium. The plug can be rotated 90 ° to connect or cut off the through hole of the valve body.
14. Manual valve: A valve operated manually.
15. Automatic control valve: A valve that does not require manual operation, whether directly or indirectly, and is mainly operated by proportional action.
16. Self control valve: A valve that operates on its own by receiving necessary power from the controlled medium.
17. Power drive control valve: A valve operated by an external auxiliary power source.
18. Regulating valve: Same definition as automatic valve.
19. Control valve: A type of valve that drives a valve and performs proportional action after receiving signals from the regulating part that are incorporated into the control system.
20. Remote operated valve: A valve that is operated or signaled from a distance. Most of these valves are controlled by the action of opening and closing two positions.
21. Stop valve: A valve in which the valve stem drives the valve disc to move perpendicular to the sealing surface of the valve body or seat. There should be at least one bend on the flow channel.
22. Rotary valve: a valve that controls the passage connection or disconnection through the remote control of the opening and closing components.
23. Industrial valve: A valve used in the industrial production of various products after raw material processing. Excluding valves for medical and laboratory purposes.
24. Valves for building facilities: valves used for water supply and drainage sanitation equipment, air conditioning equipment, and fire extinguishing equipment in buildings.
25. Power plant valve: a general term for valves used in thermal power plants and nuclear power plants, mainly for steam and circulating water systems.
