Crown Engineering H24-30 Spiralink Coupler 322838-752 the actuator drives the valveThe Crown Engineering H24 30 Spiralink Coupler is a heavy duty, one piece alternative to traditional 4 spring "fly away" couplings found in hydronic circulator pumps. Engineered for 1 2" x 1 2" shaft sizes, this CCW (Counter Clockwise) coupler features a unique single spring design that provides 3 dimensional flexibility. This allows the assembly to act as a universal joint, compensating for shaft misalignment that typically destroys standard
