FLUID POWER: Beswick Engineering’s miniature three-stage diaphragm high pressure regulator “PRD3HP” has been selected as a 2009 Design News Golden Mousetrap - Best Product Finalist! An unparalleled combination of size and performance in a high pressure regulator, the PRD3HP is capable of handling inlet pressures up to 3,000 psi, weighs approximately 79 gm in brass and is about 1 inch in diameter. It sets an industry standard for both miniaturization and light weight with its compact design. It accurately reduces inlet pressures as high as 3,000 psi down to an outlet pressure range of 0-30 psi and is especially suited to low pressure regulation such as ½ psi with minimal droop or rise, even with wide swings in inlet pressure. The PRD3HP eliminates the need for two pressure regulators (one to reduce the high pressure to an intermediate pressure and a second pressure regulator to reduce the intermediate pressure to the low pressure.)The Beswick three-stage diaphragm regulator is an excellent choice if the inlet pressure will decay over time such as with hydrogen storage tanks commonly used in hydrogen fuel cell applications. Applications include hydrogen fuel cells, medical equipment, instruments, laboratory equipment, ink jet print engines and semiconductor manufacturing equipment.
