(17) Gas pressure regulators are necessary to step down gas supply pressure to pressures suitable for various Gas various burner/combustion applications.
(3) MRO regulators serve as the control device in a cross-connected oil-air delivery system requiring wide turndown and low flow rates. They function properly over a wide range of air pressures. For single or multiple burner applications.
The Hauck PCR Pilot Control Regulator provides combustion system ratio control in preheated air applications that have changing mass flows due to density changes. The PCR is sensitive and accurate and operates with ambient temperature to 150°F. The regulator holds a constant air/fuel ratio from cold startup through preheated air operation. The components are on the cold side of the system, reducing cost and maintenance.
(4) The Hauck PRO Oil Pressure Regulator is designed to function as an inexpensive, rugged, self-contained pressure reducing valve. Its self-contained design eliminates the need for external actuators or control lines. The PRO was specifically engineered for use on oil supply systems where it is desired to automatically reduce a high oil pressure to a lower oil pressure and maintain that lower pressure within close limits.
(7) Hauck RRG regulators are carefully factory balanced to maintain a precise gas-air ratio for nozzle mix burners which use low pressure air and gas. When cross-connected to a control air line (see typical piping schematic), these regulators automatically proportion the gas delivery pressure in response to varying air pressure in the air control zone, enabling single valve firing control.
The proper operation of a cross-connected gas regulator requires that the gas supply pressure be equal to the sum of the maximum control air line pressure plus the gas pressure drop through the regulator at high fire. If the gas pressure is high enough, an air bleeder valve is not required. If the gas pressure is too low or the air pressure is too high, an ...
