Miniature Two-stage Diaphragm Pressure Regulator with 10-32 Threads
Press release date: July 27, 2006
Beswick Engineering designs and manufactures high-performance miniature fluid power devices.
Beswick introduces a new two-stage non-relieving diaphragm regulator PRD3-ANB-C-DEF. The new PRD3 pressure regulator is the third generation of our award winning PRD series of regulators. It improves upon the Beswick original two stage diaphragm regulator PRD2 by incorporating larger 10-32 ports for higher flow and easier integration into systems. The new pressure regulator also includes an improved valve design.
The "PRD3" two-stage pressure regulator retains the major advantages of Beswick "PRD2" two-stage pressure regulator, such as compact size, light weight, precise control of output pressures from 0 to 20 psig, etc. It is roughly the size of 10 quarters stacked on top of each other. It weighs approximately 23 grams in aluminum and 50 grams in brass and stainless steel. It controls output pressures from 0 to 20 psig and is especially suited to low pressure regulation such as ½ psig. The maximum rated inlet supply pressure is 500 psig. Normally small regulators are subject to droop and rise of the output pressure setting with wide swings in input pressure however the PRD3 regulator maintains a constant output pressure despite input pressure swings.
The PRD3 has three major characteristics that make it innovative and high performance. The device features a low-friction sensor and a proprietary valve arrangement to achieve excellent regulation. An innovative spring arrangement gives this regulator the capability of handling a range of regulated output pressures while maintaining a very small envelope. The stages of the regulator are "nested," keeping the regulator on a very miniature scale. The superior performance of the PRD3 makes it a perfect choice for applications with varying input pressures, such as with a gas storage tank where the pressure decreases as the gas is consumed. It allows other new and more innovative products to be made into a small envelop. Such products can be found in Portable Fuel Cells, UAV Aircraft, Instrumentation Equipment, and other applications where size and weight are critical.
Applications include: Instrumentation Devices, Portable Fuel Cells, UAV Aircraft, Portable Medical Equipment, Miniature Jet Engines, Toxic Gas Detection, Ink Jet Print Engines, Pharmaceutical Machinery and many more.
