Two-stage pressure diaphragm regulator excels in small envelope

Beswick Engineering has introduced a new two-stage non-relieving diaphragm regulator, the PRD3–ANB-C-DEF. The new PRD3 pressure regulator is the third generation of the company's PRD series of regulators. It improves upon the Beswick original two-stage diaphragm regulator by incorporating larger 10-32 ports for higher flow and easier integration into systems. The new pressure regulator also features an improved valve design. The PRD3 two-stage pressure regulator carries over elements from prior systems such as its lightweight, compact size, and control of output pressures from 0 to 20 psig. It is roughly the size of 10 quarters stacked on top of each other, weighing approximately 23 grams in aluminum and 50 grams in brass and stainless steel. It is especially suited to low pressure regulation such as ½ psig, while the maximum rated inlet supply pressure is 500 psig. 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 it on a very miniature scale. The PRD3 is designed 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 such as portable fuel cells and instrumentation equipment to be designed into a small envelop. Beswick Engineering Co., Inc. Greenland, NH beswick.com
