SAIR Enterprises is counted amongst the prominent dealer and distributor of a wide range of Pressure Regulators. Pressure Regulator is a valve that automatically cuts off the flow of a liquid or gas at a certain pressure. Regulators are used to allow high-pressure fluid supply lines or tanks to be reduced to safe and/or usable pressures for various applications. Pressure Regulators for compressed air preparation: Standard regulators, precision pressure regulators, electronically controlled pressure regulators and regulator manifolds. The accuracy of a regulator is typically defined by charting a given outlet pressure versus flow rate. The resulting chart shows a reduction in the outlet pressure as the flow rate increases. This is a phenomenon known as droop. Pressure regulator accuracy and capacity are defined by the amount of droop for a given range of flows. The performance curve for a given pressure regulator should be carefully examined to insure the regulator meets the needed performance requirements.
