The Problem
• Kestrel introduced an isolation policy that mandated the use of locks when isolating plant and equipment on site.
• It was identified that the one-inch valves could not be positively isolated via lockout.
• Kestrel had approximately 500 one-inch minsup econovalves throughout the air and water reticulation system on site

The Process Steps
• Preliminary rough sketch designed
• Consultation with on site local engineering company to make a prototype
• Manufacturer (Dixon Minsup) given the prototype and asked to supply Kestrel with the device that could be retro fitted to our existing valves

The Solution
• This engineering modification allowed us to retro-fit without removal of existing valves from service.
• The modification allows two holes to line up when the valve is in the closed position.
• Locks can now be applied to the valve whilst in the closed position providing positive isolation.

The Benefits• The one-inch valves can now be positively
isolated via lockout.

Costs• Extremely cost effective as it allows
modification to existing valves.
• It is a “one-off” expense.
• $17 per valve.
Transferability• Applicable in all industries using one-inch
water and air lines with Minsup econovalves.
