aluminum bronze valve|Valve knowledge: valve terms

1) General purpose valve
A general term for valves with a wide range of uses, also known as ordinary valves. It is not a valve for specific conditions and specific purposes.
Although there is no clear definition for general valves, they mainly refer to manually operated globe valves, gate valves, check valves, butterfly valves and ball valves with pressures below 2MPa. The valve housing materials mainly include gray cast iron, ductile cast iron, malleable cast iron, and carbon steel. , Stainless steel and bronze, etc.

2) cast iron valve
The valve body and bonnet material of the pressure-bearing shell are made of cast iron.

3) Cast steel valve
The valve body and bonnet material of the pressure-bearing shell are made of carbon steel and low-alloy steel castings.

4) Stainless steel valve
The valve body and bonnet material of the pressure-bearing shell are made of stainless steel.

5) bronze valve
The valve body and bonnet material of the pressure-bearing shell are made of bronze. And bronze valves are mostly flanged and threaded valves with a nominal pressure of 20K or less and a nominal diameter of 100 or less.

6) Brass valve
The valve body and bonnet material of the pressure-bearing shell are made of brass. Brass valves are relatively small diameter valves that are stocked, cast and forged.

7) Forged valve
The valve body and bonnet are formed by free forging or die forging process. Forged valves generally use brass, carbon steel, alloy steel, stainless steel and other materials, and most of them are valves with relatively small diameters.

8) plastic valve
Also known as plastic valve. It is a valve made of rigid polyethylene, chlorinated polyvinyl chloride and other materials. Although this valve has excellent corrosion resistance, it is limited to use under normal temperature and low pressure conditions.

9) Ceramic valve
The main part is a valve made of ceramics. It has good corrosion resistance and wear resistance, but the impact of mechanical shock and thermal shock on this valve needs to be considered when using it.

10) Faucet
It is installed at the end of the water supply and hot water supply pipes of building facilities and waterway facilities to control the opening and closing elements of the flowing water.
Valves usually make the inlet and outlet ends at the same time as pressure-bearing parts, but most faucets only need to make the inlet end as pressure-bearing parts, and the outlet end exposed to the air is made as non-pressure-bearing parts.

11) Stop cock, stop valve
It is a cock installed in the water supply pipeline to cut off the flow of water.

12) Snap tap, ferule
The faucet used when branching pipes in water supply pipes.

13) Cock
A conical or cylindrical valve body is equipped with a rotatable plug to cut off the equipment assembly of the medium. Rotate the plug 90° to connect or cut off the through hole of the valve body.

14) Manual valve
A valve operated by manpower.

15) Automatic control valve
Whether it is direct or indirect operation, it does not require manpower, and mainly depends on the proportional action to operate the valve.

16) Self-control valve
The operation of the valve requires a valve that receives the necessary power from the controlled medium to act on its own.

17) Power drive control valve
The operation of the valve relies on the power of an external auxiliary power source to manipulate the valve.

18) Regulating valve
It is the same as the definition of automatic valve.

19) Control valve
A type of actuated valve, a valve that performs proportional action after receiving the signal from the regulating part that is programmed into the control system.

20) remote operated valve
It is a valve that operates the valve from a long distance or sends a signal to operate the valve. Most of these valves are operated by opening and closing two positions.

21) stop valve
The valve stem drives the valve disc to move perpendicularly to the sealing surface of the valve body or valve seat. At least one bend in the runner.

22) Rotary valve
The valve that is connected or cut off by the remote control of the flow passage through the rotation of the opening and closing part.

23) Industrial valve
After the raw materials are processed, various products are processed into valves used in industrialized industries. Does not include valves for medical and laboratory use.

24) Valves for building facilities
Valves used for water supply and drainage sanitation equipment, air-conditioning equipment, and fire extinguishing equipment of buildings.

25) power plant valve
Used in thermal power plants and nuclear power plants, mainly as a general term for valves used in steam and circulating water systems.
