1-1/2" L-Port 3-Way Ball Valve for Flow Diversion Applications

The 1-1/2" L-port 3-way ball valve is designed for threaded piping systems requiring directional flow control and flow diversion between multiple process lines. Unlike a T-port valve, an L-port valve directs flow between two ports at a time, making it suitable for applications where flow must be switched between different outlets or process circuits.

Manufactured from 316 stainless steel, this valve provides excellent corrosion resistance and durability in demanding industrial, process, chemical, and fluid handling environments. The standard port (reduced port) design offers a compact flow path while maintaining reliable performance in threaded piping systems.

Rated to 1000 PSI, this threaded 3-way ball valve features female NPT connections for installation into standard piping systems. PTFE seats provide dependable sealing performance, while the blow-out proof stem, locking handle, and integrated mounting pad support safe operation and future automation capability. Common applications include process control systems, tank selection systems, fluid transfer systems, water treatment equipment, OEM machinery, and industrial piping systems.

1-1/2" L-Port Ball Valve Uses and Applications

A 1-1/2" L-port 3-way ball valve is commonly used in threaded piping systems requiring directional flow control and flow diversion between multiple process lines. These threaded stainless steel valves are widely used in process control systems, tank selection systems, chemical processing equipment, water treatment systems, OEM machinery, instrumentation systems, and industrial fluid handling applications.

This 1-1/2 inch L-port ball valve allows operators to switch flow between different outlets while maintaining reliable shut-off performance, corrosion resistance, and installation flexibility in threaded piping systems.

Why Choose a 1-1/2" L-Port 3-Way Ball Valve

The 1-1/2" L-port 3-way ball valve provides directional flow control between multiple process lines within a compact valve body. It is commonly used where flow must be diverted between separate circuits without mixing the media.

• L-port configuration allows directional flow control and flow diversion
• 316 stainless steel construction provides corrosion resistance and durability
• Locking handle helps secure valve position during operation
• Mounting pad supports actuator installation and automated operation

When to Choose a 1-1/2" L-Port 3-Way Ball Valve
