Product Detail: |
The Marsh Bellofram BelGAS Type P39 is the industry’s largest and most easily configurable gas pressure regulator. Units are offered with a choice of three different seat materials, allowing the designer to custom fit for individual applications. In addition, our broad selection of six different outlet pressure spring ranges allows for more precise regulation of downstream pressure for better process control. Piping designs can be simplified by using any one (or all) of the regulator’s three standard outlet ports. In addition, all units come standard with a four-seat valve disk block, which can easily be rotated 90° as needed to provide a fresh valve disk sealing surface (spark disks provided).
