4 Way Brass Ball Valve | L-Port Diverter, 3-Piece Full Port
Browse our durable 4 way brass ball valve for reliable flow diversion. Full port, L-port design, and NPT connections. Ideal for industrial water and gas control.
Description
The 4-way brass valve is a high-efficiency flow control device specifically designed for piping systems that require multiple flow-direction switching within a single valve body. Compared with standard 2-way or 3-way ball valves, this 4-way brass valve utilizes a unique L‑port or T‑port ball channel to achieve media mixing, Diversion, or 180 degree flow reversal
Manufactured from high-quality forged brass, the 4-way brass valve offers excellent corrosion resistance and dezincification resistance, making it an ideal choice for precise flow control in commercial buildings, HVAC systems, and industrial gas pipelines.
Structure & Materials
This valve series features a 3‑piece ball valve design, enabling easy in‑line maintenance and cleaning. The seats and seals can be replaced without removing the entire valve from the pipeline.
The body and end caps are precision‑forged from brass, ensuring structural strength under high‑pressure conditions. The ball is made of chrome‑plated solid brass, precision‑polished to form a tight seal with PTFE (polytetrafluoroethylene) seats, which effectively reduces operating torque and guarantees zero leakage shut‑off.

Application Scenarios
The 4‑way ball valve operation is highly flexible and is commonly used in the following applications:
-
HVAC Systems: For switching between supply and return branches in heat exchangers or chiller units, enabling seasonal changeover from cooling to heating modes.
-
Water Treatment & Filtration: Installed in duplex filter systems, allowing flow to be directed to either filter #1 or #2 by switching the ball position, thus enabling online cleaning and maintenance.
-
Gas Supply Pipelines: As an upgraded alternative to L‑port 3‑way ball valves, used in natural gas or liquefied gas lines where full bypass or bi‑directional shut‑off is required.
-
Industrial Equipment Cooling: In recirculating systems that require alternating operation between two cooling towers or chillers, used to divert and shut off coolant flow as needed.
