ISO-K Claw Clamp Bored Flange

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.
