Tap valve parts consist of several key components that work together to control the flow of water in taps or faucets. These components include the valve body, valve stem, washer, and handle, each playing a specific role in the operation of the tap.

The valve body serves as the housing for the valve mechanism and is typically made of durable materials such as brass, stainless steel, or plastic. It provides stability and support for the other components while also containing the water flow channels.

The valve stem is a cylindrical shaft connected to the handle that controls the opening and closing of the valve mechanism. When the handle is turned, the valve stem moves up or down, allowing water to flow through the tap or shutting off the flow completely.

The washer is a small, flexible disc or ring located at the end of the valve stem. It forms a watertight seal against the valve seat when the tap is closed, preventing water from leaking out. Over time, washers may wear out or become damaged, leading to leaks or drips that require replacement.

The handle is the part of the tap that users manipulate to open or close the valve mechanism. It may be a knob, lever, or cross-shaped handle, depending on the design of the tap. Turning the handle clockwise or counterclockwise controls the flow of water, allowing users to adjust the water flow rate or shut off the tap entirely.
