What is Double Lin Brass ball valve Handle 1″ ?
The Double Lin Brass Ball Valve with a 1″ handle is a high-quality, heavy-duty valve designed for reliable shut-off and flow control in water, heating, and compatible fluid systems. The manufacturer constructs the valve using high-density forged brass (HPB 57-3 or DZR brass for some models), ensuring durability, corrosion resistance, and leak-free performance. The handle typically features a lever design made from iron, steel, or aluminum alloy, and the coating enhances corrosion resistance while ensuring comfortable operation.

Description
-
- Material:
- Constructed from high-quality brass, which provides excellent durability, strength, and corrosion resistance. Manufacturers commonly use brass in valve production because of its reliability and longevity.
- Size:
- The valve has a nominal diameter of 1 inch. This size indicates the valve’s internal diameter, which corresponds to the piping system it will connect to.
- Type:
- This is a ball valve, which means it employs a spherical closure element (the ball) with a hole (port) through the center. The ball rotates when the valve handle is turned, allowing for either open (flow enabled) or closed (flow blocked) positions.
- Handle:
- It features a double-line handle, which typically consists of a lever that can be manually operated. The design allows for easy grip and quick operation. The double dimension may refer to markings or indicators on the handle for clear position visibility.
- Connection Type:
- The valve can arrive with different types of connections, such as threaded (NPT) or solder (sweat) connections, based on the requirements of the piping system.
- Working Pressure and Temperature:
- Manufacturers specify varying working pressure and temperature ratings, but brass ball valves are generally designed to handle reasonably high pressures and moderate temperature ranges.
- Material:
-
: Used for on/off control of water in residential, commercial, and industrial piping.
-
: Suitable for use in hot and cold water circuits within the specified temperature range.
-
: Compatible with non-corrosive gases (except for models specifically restricted to water services).
-
: For non-corrosive fluids compatible with brass and PTFE.
-
The valve is operated by turning the lever handle, which rotates the internal brass ball with a bore through it.
-
When the handle is parallel to the pipe, the valve opens to allow full bore flow; when it is perpendicular, the valve closes to shut off the flow.
-
Designed for reliable, quick shut-off and not for throttling or regulating flow.
-
: Minimal pressure drop when open.
-
: Tested for 10,000 open/close cycles.
-
: PTFE seats and double O-ring stem ensure leak-free operation.
-
: Brass body, PTFE seats, and coated handle provide excellent protection against corrosion and wear.
