What is Double Lin Brass Gate Valve 2-1/2″ ?
The Double Lin Brass Gate Valve, specifically in the 2-1/2″ size, is a robust and versatile valve designed for controlling the flow of water and other compatible fluids in piping systems. It is constructed primarily from high-quality brass (HPb 57-3), ensuring durability, corrosion resistance, and long service life. The valve features a cast-iron handle for manual operation, a PTFE (polytetrafluoroethylene) filler for enhanced sealing, and a stainless steel nut for added strength and reliability.

-
: Ensures no blisters, air holes, or leakage, with all major brass components precision-machined for tight tolerances and excellent sealing.
-
: Provides strength and resists deformation or fracturing under stress.
-
: Achieved via CNC machining for optimal sealing performance.
-
: Prevents leakage and enhances the valve’s sealing capability.
-
: Painted for corrosion resistance and designed for comfortable manual operation.
-
: Offers high tensile strength and durability over long-term use.
-
: Used to start or stop the flow of water in residential, commercial, and industrial plumbing.
-
: Frequently installed in standpipe systems, fire pumps, and hydrants as a control valve for fire protection water supplies.
-
: Suitable for a wide range of non-corrosive fluids within the specified pressure and temperature ranges.
-
The valve operates via a manual handwheel (cast-iron handle) that raises or lowers a brass gate inside the valve body.
-
When fully open, the gate retracts completely, allowing minimal flow resistance.
-
When closed, the gate seals tightly against the valve seat, stopping flow entirely.
-
: Allows unrestricted flow when open, minimizing pressure drop.
-
: PTFE filler and precision-machined gate ensure tight shutoff.
-
: Brass construction resists corrosion and mechanical wear, suitable for long-term use.
