Structure of Dual-Control Faucets

Dual-Control Faucets, also known as two-handle faucets, is a common type of faucet found in both bathrooms and kitchens. They feature separate controls for cold and hot water, allowing users to adjust the water temperature and flow rate by manipulating two distinct handles. The structure of Dual-Control Faucets consists of several key components that work together to regulate water flow and temperature effectively.

Faucet Body: The main body of the faucet houses the internal components and provides support for the handles, spout, and other parts. It is usually mounted to the sink or countertop.

Spout: The spout extends from the faucet body and delivers the water into the sink. It can come in various shapes and lengths to accommodate different sink sizes and styles.

Cold and Hot Handles: Dual-Control Faucets have two separate handles – one for cold water and one for hot water. These handles are typically located on either side of the faucet body and are used to adjust the water temperature by controlling the flow of cold and hot water respectively.

Cartridges or Valves: Inside the faucet body, cartridges or valves control the flow and mixing of cold and hot water. Turning the handles adjusts these cartridges, allowing water from the respective supply lines to flow through and mix at the desired temperature.

Spindle or Stem: The spindle or stem is the component that connects the handle to the cartridge or valve. When the handle is turned, the spindle or stem moves, opening or closing the valve and adjusting the flow of water.

Aerator: An aerator is usually located at the tip of the spout. It adds air to the water flow, reducing splashing and improving water pressure. Some aerators are adjustable, allowing users to control the water stream.

Supply Lines: Dual-Control Faucets require separate supply lines for cold and hot water. These lines connect the faucet to the water source, typically via flexible hoses or pipes.

Base Plate or Escutcheon: In some installations, a base plate or escutcheon may be used to cover the holes in the sink or countertop where the faucet is mounted. This enhances the appearance of the faucet and provides stability.

Sprayer (Optional): In some kitchen faucet models, there may be a separate sprayer attachment. This attachment is often connected to the faucet with a flexible hose, allowing for greater flexibility in directing water flow.

Handle Stops: Some Dual-Control Faucets come with handle stops, which can be set to a specific temperature to ensure that users do not accidentally turn the faucet to extremely hot or cold positions. This is especially useful in households with children.

Decorative Trim: The handles and other visible parts of the faucet often feature decorative trim, which enhances the faucet's aesthetic appeal and complements the overall design of the sink area.

Dual-Control Faucets are designed with a structure that includes distinct cold and hot water controls, cartridges or valves for mixing, and other components that work together to regulate water temperature and flow. While modern designs often favor single-handle or mixer faucets, Dual-Control Faucets still have a place in many homes and are appreciated for their classic design and precise temperature control.
