Parker LV8NAB Safety Lockout Valve 3-way 1 Inch Npt

Product Description

The PARKER LV8NAB is a manually operated safety lockout valve designed for fluid control applications requiring reliable shutoff and lockout capability. This 3-way valve uses a handle actuator and features a 1 inch NPT inlet with a Cv rating of 9.5, making it well-suited for systems where manual isolation and lockout/tagout compliance are required. The valve operates in 2 positions and is activated manually, giving technicians direct mechanical control over flow. It is installed by licensed plumbers, pipefitters, or industrial maintenance professionals working on fluid or pneumatic systems.

The LV8NAB is intended for applications where safety lockout valves are required by code or plant safety protocols. Typical installations include process piping, compressed air distribution, HVAC fluid systems, and similar commercial or industrial service environments. The 1 inch NPT thread connection suits standard pipe configurations. The minimum working temperature of 40 degrees F makes it suitable for indoor or climate-controlled installations.
