Other fastening methods include single claw clamps, bolted
rotatable, bolted nonrotatable
and non ISO standard MDC band clamps. Geometries for each fastening method are
Single claw clamps are ideally suited for applications where one of the mating flanges
is flush mounted and fitted with threaded bolt holes. This is typical on most MDC gate
valves constructed with Large-Flange™ ISO LF port flanges. Both the double and single
claw clamp fasteners provide unlimited rotation or positioning of mating flanges prior
to final tightening of bolts.
