Miniature manifold mount style pressure regulators

than those supplied by the PRDB pressure regulator. It controls output pressures from 0 to 30 psig and is designed to regulate pressures as low as 0.5 psig. Maximum inlet supply pressure is 500 psig. The PRDHF8 connects via a 5/16-24 UNF threaded port and weighs approximately 52g in brass and stainless steel. Typical applications for these pres- sure regulators include hydrogen fuel cells, medical equipment, instrumenta- tion, laboratory equipment, ink jet print engines and semiconductor manufac- turing equipment. The PRDB8, PRD28 and PRDHF8 have patents pending. Beswick Engineering Co, Inc – USA besales@beswick.com www.beswick.com Aluminium flanges Fonderia Fazzini has produced aluminium flanges for 40 years. The company’s range includes loose flanges for collars for steel pipes according EN-DIN-ANSI standards PN6, PN10, PN16, 150LB; blind flanges PN 10/16; loose flanges for PE/PVC plastic pipes UNI-DIN PN10/16; and special flanges according to customers’ drawing.

approximately 25g in stainless steel. The PRD28 two-stage manifold regulator can also accurately reduce high-pressure inputs (up to 500 psig) down to 0 to 20 psig. It is designed to regulate pressures as low as 0.5 psig, and exhibits minimal droop and rise even with wide swings in inlet pressure and flow. The regulator is suited to applications such as regulating fuel gas pressures from storage tanks, where the inlet pressure decays significantly over time. The PRDB28 connects via a 5/16- 24 UNF threaded port and weighs approximately 52g in brass.

Beswick Engineering has launched manifold mount versions of its miniature pressure regulators. These models include the PRDB8 high accuracy, single stage pressure regulator, PRD28 two-stage pressure regulator, and the PRDHF8 high flow regulator. The PRDB8 regulator is amanifoldmount version of Beswick’s PRDB pressure regulator with a patent-pending valve mechanism designed to provide high precision/high reliability at low flows and at low set pressures. It controls output pressures from 0 to 30 psig and is particularly suited to regulating pressures as low as 0.5 psig. The PRDB8 connects via a 10-32 UNF threaded port. Its maximum supply pressure is 500 psig and it weighs

The PRDHF8 regulator is used in applications that require higher flows

Metal pipe fittings Jiangyin Tianning Metal Pipe Fitting Co Ltd, founded in 1990, specialises in the manufacture of straight and reducing tees, 90° and 45° elbows, concentric and eccentric reducers, caps, crosses, stub ends, flanges and forged fittings, according to ASME, ANSI, MSS, JIS, DIN, GB, SH and HG.

Fonderia Fazzini’s Lite flanges S S

Pipe fittings from Jiangyin Tianning S S

The company’s patented Lite flanges feature an exclusive truncated cone shape, allowing them to be 30% lighter than current aluminium flanges. Loose aluminium flanges are an interesting alternative to those made from other materials, and they benefit from the characteristics of aluminium, including light weight, hardness, corrosion resistance and cost efficiency.

The products range in size from ½" to 64", in thicknesses from SCH5S to SCHXXS. The products have been supplied to major projects for domestic and international markets, and are used in oil and gas, power plant, chemical, metallurgy, electricity, ship-building, paper making and water supply industries. The company’s strict inspection policy covers every aspect of the production process, from purchasing of raw material to delivery of products. The company has obtained ISO9001:2000 quality management system certification, PED 97/23/EC, AD2000-Merkblatt/W0 certifications under TÜV approval, and has become a supplier member of Sinopec Materials Source Market and National Petroleum Corporation Materials Source Market.
