The high-flow range includes diaphragm or piston-sensed regulators with port sizes ranging from 1/2″ to 3″, and threaded or flanged connections. Pressure control options up to 10 bar (145 psi) with a diaphragm or up to 210 bar (3,045 psi) with a piston. Also available with spring-loaded or dome-loaded to minimise the droop effect on the regulator.
