Tap Valve Top
A tap valve top, also known as a faucet handle or valve bonnet, is the component of a tap (faucet) that the user manipulates to control the flow of water. It's the visible, often decorative, part of the valve assembly.
Material
Tap valve tops are commonly manufactured from:
- Brass: A traditional material, offering durability and a classic aesthetic. Often coated with finishes like chrome, nickel, or gold.
- Zinc Alloy: A more affordable alternative to brass, providing reasonable durability with various plating options.
- Stainless Steel: Highly corrosion-resistant and modern in appearance.
- Plastic (ABS, PVC): Used in lower-cost or specialized applications; generally less durable than metal options.
- Ceramic: Found in some lever handles, offering a smooth feel and resistance to wear.
Purpose
The primary purpose of a tap valve top is to provide a user interface for:
- Turning water flow on and off: By rotating or lifting the top, the valve mechanism is activated or deactivated.
- Controlling water temperature: In mixing taps, the top allows adjustment of the hot and cold water blend.
- Adjusting water flow rate: Some designs allow for variable flow control.
Function
The tap valve top functions by:
- Connecting to the valve stem: The top is securely attached to the valve stem, which moves within the valve body.
- Translating user input into valve stem movement: Rotation or lifting of the top directly corresponds to the movement of the valve stem.
- Sealing the valve body: The top often incorporates seals (O-rings, washers) to prevent water leakage around the stem.
Usage Scenarios
Tap valve tops are found in a wide range of applications:
- Residential plumbing: Kitchen faucets, bathroom sinks, bathtubs, showers.
- Commercial plumbing: Public restrooms, kitchens, industrial facilities.
- Outdoor taps: Garden hoses, irrigation systems.
Common Types
- Knob Handles: Traditional, typically two separate knobs for hot and cold water.
- Lever Handles: Single lever controls both temperature and flow. Common in modern designs.
- Cross Handles: Four arms forming a cross shape; often found in older plumbing systems.
- Wheel Handles: Circular wheel shape, typically used for industrial or specialized applications.
- Touchless/Sensor Handles: Electronic handles activated by motion or touch.
- Ball Valves: Utilize a ball with a bore to control water flow; often found in kitchen faucets.
- Cartridge Valves: Utilize a cartridge to control water flow and mixing; common in modern single-handle faucets.
