Spectacle blinds consist of a connected ring (spacer) and a plate (spade). If a piece of equipment needs to be inspected or removed from service then the plate covers the ring to form an airtight seal which consequently isolates a section of line or the piece of equipment. It provides a permanent or long term isolation device.
Our spectacle blinds are designed to ensure that an item of equipment can be securely blanked off, with no possibility of leakage in the valve.
Spades and spacers are similar to spectacle blinds, except that they are not attached to one another. They are designed to isolate sections of pipe to prevent contamination and allow inspection.
Because safety is so important to the function, we assure that they are tested rigorously to client’s specifications.
Our spectacle blinds, spades and spacers come in pressure ratings of 150lbs, 300lbs, 600lbs, 900lbs, 1500lbs and 2500lbs
