ISO Flange Assembly Instructions
Optional fastener flanges are joined around the periphery with clamps.
Double claw clamps are used when a pair of OF flanges are joined (See diagram A.),
or single claw clamps are used to join an OF flange to a tapped nonrotatable on a pump or gate valve. (See diagram B.)
This fastening method allows the OF flange to be rotateforease of component alignment. Additionally, a rotatable bolt ring can be used
to fasten an OF flange to a nonrotatable flange using bolts. (See diagram C.)
A retainer ring prevents the OF flange from slipping through the bolt ring. Nonrotatable ISO flanges are assembled with bolts.
(See diagram D.) They do not allow rotation of bolt holes on mating flanges to align components.
ISO Double Wall Clamp
The Double wall Clamps are designed to be used with the following sizes: ISO 160, ISO 200, ISO 250.
The Double wall Clamps are available in Aluminum.
ISO Flange Series are comprised of two smooth face flanges clamped together with a combination of metal centering rings, and elastomeric O-Rings. The clamps can be used to connect an ISO flange to a pump, chamber or gate valve.
