Parker LV6N6B Safety Lockout Valve 3-way 9.5 Cv Npt

Product Description

The PARKER LV6N6B is a manually operated safety lockout valve designed for positive flow shutoff in industrial and mechanical systems where lockout/tagout compliance is required. Actuated by a handle with two positions, this 3-way valve delivers a Cv rating of 9.5 and uses NPT threaded connections. The minimum working temperature is 40 degrees F. It is typically installed by licensed pipefitters, millwrights, or mechanical contractors as part of energy isolation procedures on pneumatic or fluid control systems.

This valve is suited for applications where technicians must isolate and lock out a fluid or air circuit before performing maintenance or service. The handle actuator provides a clear visual indicator of valve position, supporting safe lockout/tagout (LOTO) protocols. Common install scenarios include compressed air distribution lines, hydraulic circuits, and process piping headers in commercial and light industrial environments. The 3-way design allows for venting or redirecting flow when the valve is placed in the off position.

Key Features

• 3-way valve design with 2 positions for positive flow isolation and optional circuit venting
• 9.5 Cv rating provides adequate flow capacity for typical industrial pneumatic and fluid lines
• Handle actuator gives clear visual position indication and supports LOTO compliance
• NPT threaded connections for straightforward integration into standard pipe systems
• Rated for service down to 40 degrees F minimum working temperature
• Manual activation requires no electrical signal or external power source

Compatibility

Designed as an OEM-style replacement or direct-fit addition for pneumatic, hydraulic, or fluid process piping systems requiring NPT-threaded manual safety lockout valves.

Installation Notes

Installation should be performed by a qualified pipefitter or mechanical technician in accordance with applicable OSHA lockout/tagout regulations and local mechanical codes. Depressurize and isolate the system completely before removing any existing valve or fitting the LV6N6B into the line. Verify that thread sealant or tape is applied correctly to NPT threads to prevent leaks, and confirm the valve position indicator is accessible and visible after installation. Do not exceed the valve pressure and temperature ratings listed by the manufacturer.
