Parker LV4N6B Safety Lockout Valve 3-way 9.5 Cv Npt

Product Description

The PARKER LV4N6B is a manually operated safety lockout valve designed to isolate fluid or gas flow in industrial and mechanical systems. Actuated by a handle, it operates in two positions and features a 3-way design with a Cv rating of 9.5, making it suitable for moderate-flow control applications. The valve uses NPT threaded connections for straightforward installation into standard piping. Weighing 2.4 pounds, it is a robust, hands-on shutoff device relied upon by maintenance technicians, pipefitters, and mechanical contractors who require a dependable manual isolation point with lockout capability.

This safety lockout valve is intended for use in industrial process lines, HVAC mechanical rooms, and utility piping where positive manual shutoff and lockout tagout (LOTO) compliance are required. Its handle actuation and two-position operation make it well suited for maintenance isolation procedures on compressed air, gas, or fluid systems. A minimum working temperature of 40 degrees F makes it appropriate for most indoor mechanical and light industrial environments. Licensed tradespeople and plant maintenance personnel are the primary installers and operators of this valve.
