G56/G57

Pilot-controlled gas pressure regulators of series G56/G57 keep the outlet pressure at a constant level, regardless of the flow volume and inlet pressure. The G56 regulator is designed for pressures up to 40 bar (ANSI 300), and the G57 regulator for pressures up to 100 bar (ANSI 600). Both operate either on a "fail to close" or "fail to open" principle.
