What are the names of valve fittings

Release time:


Valve fitting designations include, but are not limited to, the following:

Valve Body. As one of the main components of the valve, it is used to hold the other parts of the valve in place and to support the valve flap and seal.
Valve stem. A component that connects the valve flap to the manual mechanism, the quality of which directly affects the sealing performance of the valve.
Valve seat. A gasket inside the valve, used for sealing, the specific shape varies with the valve structure.
Valve plate. Valve seals, generally composed of valve flap and valve seat, due to the different working media, the shape of the valve plate is also different.
Valve stem nut . Used to connect the valve stem and the manual mechanism, in order to adjust the degree of opening of the valve.
Valve stem bushing. A type of seal used to prevent wear from friction when the valve stem is in contact with the valve body.
Sealing Gasket. Placed between the valve seat and valve flap to prevent fluid leakage.
Flange. A key component used to connect a valve to a pipeline, consisting of two flanges with a gasket in the center.
Switch Indicator. Installed on the handle, used to visualize the switching status of the valve.
Transmission device. This is an additional component on large valves to enable remote control.
Actuator. Plays a key role in automatic control systems and is used to precisely control the valve.
Lining. For special fluids and applications, the lining plays a key role and is usually made of materials such as PTFE and hard rubber.
Together, these components form the complete structure of the valve, ensuring proper operation and performance.
