Features Provides reliable, constant and stable reduced pressures. Highly sensitive pilot valve provides a constant outlet pressure, irrespective of erratic inlet pressure or system demand. Provides very close accuracy of pressure control. Choice of bronze or carbon steel constructions. Threaded or flanged models available. High flow rates enable specification of smaller valves than the comparable direct acting valve. Fully compliant with and certified to the Pressure Equipment Directive (PED). Surplus/maintaining valves available to provide an economical solution for secondary or non-critical processes.
