Prevost Lock Kit For Valve

Description

Prevost Lock Kit for Ball Valves

Essential Safety Compliance for Compressed Air Isolation

The Prevost Lock Kit is a vital safety accessory designed to convert standard Prevost ball valves into secure, OSHA-compliant lockout points. In industrial environments, accidental activation of an air line during maintenance can lead to catastrophic injury or equipment damage. This kit provides a robust mechanical block, ensuring that the valve remains in the “OFF” position until work is safely completed.

Engineered specifically for the PPS (Prevost Piping System) and Prevost’s line of brass and aluminum valves, this kit is an indispensable tool for any facility prioritizing a “Safety First” culture.

Key Features

• OSHA & LOTO Compliant: Facilitates Lockout/Tagout (LOTO) procedures by providing a dedicated attachment point for safety padlocks and warning tags.
• Tamper-Proof Design: Once installed, the bracket physically prevents the valve handle from being turned, providing a visible and mechanical guarantee that the air supply is isolated.
• High-Visibility Safety Yellow/Red: The components are typically finished in high-visibility colors to ensure the lockout point is easily identifiable by all personnel, even in low-light industrial areas.
• Universal Compatibility: Designed to fit seamlessly onto the necks of Prevost 1/4-turn ball valves, maintaining a tight, no-slip grip that cannot be bypassed without removing the lock.
• Corrosion-Resistant Construction: Built to withstand harsh shop environments, including exposure to compressor oils, moisture, and cleaning chemicals.

Why Use a Lock Kit?

Standard ball valves are easy to operate—sometimes too easy. A simple bump or a misunderstanding between crew members can restore pressure to a line while a technician is downstream. The Prevost Lock Kit:

1. Protects Personnel: Prevents accidental startup during tool changes or pipe repairs.
2. Prevents Unauthorized Use: Keeps critical air lines or expensive machinery restricted to authorized operators only.
3. Simplifies Audits: Shows safety inspectors that your compressed air network meets modern industrial safety standards.

Technical Details

Safety Recommendation

For maximum security, use this Lock Kit in conjunction with Prevost prevoS1 safety couplings. While the valve isolates the pressure, the safety couplings ensure that any residual air downstream is safely vented, creating a completely inert work environment.
