Marsh Bellofram designs and builds several types of air pressure regulators. General purpose regulators are designed for typical industrial use and operate above atmospheric pressure. High pressure regulators are rated for inlet pressures over 1000 psi, and low pressure regulators operate at pressures below 15 – 20 psi. With dual stage regulators, the media flows through successive chambers so that a constant pressure is delivered even when the pressure regulator inlet pressure decreases. View More....
