Valve Lockout Devices

Valve Lockout Devices protect workers from accidental release of pressure, fluids, or gases during maintenance or repair. These devices isolate valves in closed positions and prevent unauthorized operation, helping facilities meet OSHA 1910.147 requirements for hazardous energy control. Built for industrial strength and long service life, each lockout is designed for real-world use on pipelines, pumps, compressors, and pressure systems.

Engineered for Safe Energy Isolation

Our Valve Lockout Devices are manufactured from reinforced, non-conductive materials capable of handling heat, oil, and chemical exposure. Once locked in place, they completely block valve handles from movement until authorized personnel remove them. These devices are essential for isolating pneumatic, hydraulic, and fluid systems in refineries, manufacturing plants, and utilities.

Built for Industrial Durability

Each valve lockout is constructed from high-impact polypropylene or powder-coated steel, resistant to corrosion and temperature extremes. Adjustable designs fit a range of handle sizes and valve types. Bright safety colors improve visibility during lockout, and smooth interior surfaces protect valve coatings and handles from wear. These are not disposable plastic shells—they are professional-grade safety tools used daily in demanding field conditions.

Custom Configurations for Every Valve Type

Facilities use many valve styles, which is why we offer multiple lockout solutions for every application. Ball valve lockouts secure quarter-turn handles. Gate valve lockouts cover rising stem mechanisms. Universal cable devices can lock multiple valves simultaneously. We also offer custom sizing and color options to align with facility-specific energy control programs.

Subcategories

Ball Valve Lockout Devices
Designed for quarter-turn handles, these lockouts clamp securely over valve levers to keep them fixed in the closed position. Adjustable sizes cover small process lines to large industrial pipes.

Gate Valve Lockout Devices
Fully encloses wheel-style gate valves to prevent hand access or rotation. Available in multiple diameters with overlapping covers for a tight, secure fit.

Butterfly Valve Lockouts
Low-profile lockouts that secure butterfly valve handles and levers without interfering with adjacent equipment. Common in food processing and chemical facilities.

Cable Valve Lockouts
Flexible cable-style systems capable of locking multiple valves or isolation points at once. Perfect for complex energy control procedures or confined equipment areas.

Custom Valve Lockout Solutions
Custom-engineered to match your exact valve dimensions and facility color codes. Digital proofs provided before production for guaranteed fit and compliance.

Why Valve Lockouts Are Critical for Compliance

Valve Lockout Devices are one of the most frequently cited elements in OSHA inspections. Proper valve isolation prevents catastrophic energy releases, fluid leaks, and pressure surges that can cause serious injury or environmental damage. Using dedicated lockouts ensures your maintenance crews can isolate valves consistently across every department, with visual confirmation that energy has been safely contained.

When combined with tags and padlocks, valve lockouts form the foundation of an effective energy control program that satisfies both OSHA and ANSI requirements.

Frequently Asked Questions

What types of valves can these devices secure?

Our Valve Lockout Devices are engineered to handle almost every industrial valve configuration, including ball, gate, butterfly, and plug valves. Ball valve lockouts fit quarter-turn levers commonly used in pipelines and compressed air systems. Gate valve covers fully enclose rising handwheel designs, ideal for high-pressure lines.

Are these devices OSHA compliant?

Yes. All Valve Lockout Devices are designed and tested to meet OSHA 1910.147 and ANSI Z244.1 standards for hazardous energy control. Each design supports full energy isolation, lockout tagging, and visual verification procedures required during audits. Using these devices as part of a documented lockout program can significantly reduce citation risks during safety inspections.

Can one device fit multiple valve sizes?

Yes, several of our valve lockouts are adjustable and modular. Ball valve lockouts come in multiple sizes, and adjustable versions can handle valves from small half-inch lines up to industrial-scale 8-inch assemblies. Cable lockouts are even more versatile and they can secure irregular or hard-to-reach valves where traditional covers cannot fit.

Do you offer branded or engraved lockouts?

Yes. We can print or laser-engrave company logos, serialized IDs, or department codes directly on the valve lockouts. This makes it easier to track gear, prevent loss, and maintain accountability during audits. Custom labeling also reinforces brand professionalism and safety culture at the site lev

Do you offer metal versions for high-temperature environments?

Yes. For steam, refinery, and boiler applications, we supply aluminum and steel valve lockouts rated for high-temperature and chemical exposure. These are ideal in conditions where thermoplastics may deform or degrade, such as hot oil systems or process plants. They feature powder-coated finishes for corrosion protection and visibility even in outdoor or chemical-heavy environments.

Can these lockouts be color coded?

Absolutely. Many facilities use color-coded lockouts to identify departments, energy sources, or maintenance levels. For example, red can designate electrical isolation, yellow for pneumatic, and blue for mechanical. Custom colors, engraved numbering, and labeled identification plates can be added to match your existing lockout program or audit protocols.

How many locks can be applied to a single device?

Most lockouts are designed with multiple lock holes to support group lockout procedures. This means multiple technicians can secure their own padlocks on a single valve device during team maintenance. The system prevents reactivation until every worker removes their individual lock, ensuring compliance with OSHA’s group energy control requirements.

Are replacement cables available for cable lockouts?

Yes. Replacement cables and locking heads are stocked and can be ordered individually for quick field swaps. We also provide different cable lengths and coatings for oil, chemical, and outdoor environments to extend the lifespan of your system.
