Pro-source 4530231011PRO 3-way Manual Lever Valve

Product Description

The PRO-SOURCE 4530231011PRO is a manually operated 3-way valve actuated by a hand lever with detent positioning. It is designed for fluid or pneumatic control applications where a reliable, tool-free directional shutoff or diverting function is required. The valve carries a Cv rating of 0.976 and uses NPT threaded connections for straightforward integration into standard piping systems. With two positions and detent-lock actuation, the lever stays in place without spring return, reducing the risk of accidental shifting during operation. Plumbers, pipefitters, and mechanical contractors install this type of valve in process lines, hydraulic circuits, and fluid distribution systems.

This valve is suited for light industrial, commercial, and mechanical-room installations where manual directional control of flow is needed. Its compact footprint, measuring 3.13 inches in length, 3.97 inches in height, and 1.38 inches in width, allows it to fit in tight plumbing or process-piping assemblies. The detent mechanism keeps the selected position locked until the operator deliberately moves the lever, making it appropriate for systems that require a defined open or diverted state to be held between service intervals.

Key Features

• 3-way, 2-position lever detent actuation for positive position retention
• Cv rating of 0.976 for sizing in low-flow control circuits
• NPT threaded ports for direct integration with standard pipe fittings
• Compact body at 3.13 inches long and 3.97 inches tall
• Manual mechanical operation requires no electrical or pneumatic actuator
• Lightweight at 0.46 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement or new-installation manual 3-way valve for residential and light commercial plumbing, HVAC, and process-piping systems using NPT threaded connections.

Installation Notes

A licensed plumber or pipefitter should install this valve in accordance with applicable IPC or local mechanical codes. Shut off and depressurize the supply line fully before disassembly or installation. Use thread sealant or PTFE tape rated for the media and pressure of the system on all NPT connections. Verify flow direction and port assignment against the system schematic before applying pressure to the completed assembly.
