Industrial gas pressure regulators three-outlet port design

Marsh Bellofram Groupvisit website


Marsh Bellofram Corporation is introducing its Type T39 Series, a family of cost-effective standard industrial gas pressure regulators, offering precision monitoring and control within control valve supply, instrumentation column, air set, downstream, low flow and other general purpose applications.

Design of the Bellofram T39 Series includes one (1) ¼” inlet and three (3) ¼” outlet ports. This makes it the only industrial gas pressure regulator currently on the market to incorporate three outlet ports within a single regulator. The advantages presented by this design include peak application performance and versatility at a low price point. Piping designs may be also be simplified by using any (or all) of the three available outlet ports. Bellofram T39 Series regulators are also available with choice of seat material, fitted for the application.

Standard Bellofram T39 Series regulators are available in six spring pressure ranges from 0-30 PSIG to 0-225 PSIG. This broad offering allows for more precise downstream industrial gas regulation than can typically be achieved via a comparable standard industry unit. The bonny, bonnet and bonnet plug of the T39 Series are all constructed of brass. The regulators further incorporate 302 stainless steel diaphragms. Electroless nickel and stainless steel housings are available upon request. Each Bellofram T39 Series regulator also comes with a four-seat valve disc block. The block can be easily rotated 90 degrees to provide a fresh valve disk sealing surface. Spare valve disks are provided. Regulators may also be easily converted from tamper-resistant to T-handle adjustment, or vice versa. Both adjustment assembly types are supplied as standard and are shipped along with the product.

Bellofram T39 Series industrial gas pressure regulators can also be modified for specialty service. Typical modifications can include, but are not limited to: inclusion of a 500 PSI outlet; dual inlet ports; nickel plated and stainless steel materials; and tapped vents on all stainless steel units. Please consult the factory for details.

All Bellofram industrial gas pressure regulators are 100 per cent made in the USA at the company’s state-of-the-art manufacturing facility in Newell, West Virginia. Each product is rigorously tested for durability and performance prior to shipment. They are also offered to customers with 10-day standard product lead times and are supported by a fully active global distribution network.
