REGULATORS TECHNICAL DATA COMPONENTS

Transcription

1 RUTORS ach system served by the air supply mains (e.g. actuators and general appliances) requires its own constant operating pressure. t is necessary to use a regulator to regulate the pressure within a set range by means of regulating springs, with the pressure never exceeding the mains pressure. The new Skillair regulator uses a rolling diaphragm which gives a much better performance than the flat version. dvantages of this system: ncreased stroke, increased valve opening and hence higher flow rate. ecreased dynamic and inrush friction; prompter, more sensitive operation. Reduced working stress and hence longer life allowing the use of thinner diaphragms (0.45 mm versus.5 mm for a flat one) which increases regulator sensitivity and prompt action. ncreased accuracy in maintaining the set pressure with both variable flow rates and different feed pressures. ownstream overpressures relieved quickly.
