Thermodynamic steam trap with inbuilt strainer and full stainless steel construction, best suited for header and mainline drains and drop legs.  The TD-3 Thermodynamic Steam Trap is suitable for draining main steam distribution lines where prompt removal of condensate is essential. The TD-3 uses the velocity and phase change of pressurised condensate flashing to lower pressure steam to operate the disc. Its hardened seat and disc and absence of moving parts ensures a long service life. Although the trap operates in any position, horizontal orientation is preferred.  

FM PISTON VALVE is a zero leak isolation Piston Valve, in which the seat & gland are replaced by Lower & Upper Sealing rings along with a Piston. This overcomes the difficulties usually associated with the replacement of conventional seats.  The FM Piston valve is the name for prevention of inline leakage as well as leakage through glands, making for leakproof isolation in the pipelines.  The FM Piston valve is a seat less & gland less Piston Valve. At the heart of the FM piston valve are Piston & sealing rings. A burnished piston seals against SS reinforced graphite rings to achieve a leak proof shutoff. This unique design ensures a long life even at high temperatures up to 427 deg C  A Burnished piston is connected to the Piston Valve stem & hand wheel. The piston passes through two sealing rings separated by a lantern bush. Each sealing ring is Stainless steel reinforced graphite, which has both features of sustaining compression exerted by Bonnet & providing soft seal against piston. The upper sealing ring acts as a conventional gland packing and prevents leakage towards atmosphere. The lower sealing ring acts as the seat which prevents in line leakage. The lantern bush is required to maintain separation between the upper & lower rings & to allow flow through the Piston Valve.

FORBES Disc Check Valves are recommended after traps discharging into closed systems to guarantee against return or spill back. DCVs feature a compact and rugged stainless steel design and are suitable for any process liquid & gas, not just steam. Main advantage of these check valves is they can be mounted between pipe flanges in any direction.  DCV 1, 2, 3 DCV 1, 2 and 3 Disc Check Valves are designed to be sandwiched between flanges i.e. wafer type. They are suitable for use on a wide range of fluids for applications in process lines, hot water systems, steam and condensate systems etc.  DCV 4 Wafer Check Valve The DCV 4 Disc Check Valve is designed to be sandwiched between ANSI flanges. It is suitable for use on a wide range of fluids for applications in process lines, hot water systems, steam and condensate systems etc.

Fitted on your feedtank, the FORBES Deaerator Head mixes cold make-up water, hot condensate, and flash steam in a single stainless steel (SS) head to get the most out of your captured heat.Cold make-up water atomizes in the mixing head releasing 90% of dissolved oxygen, a primary source of downstream corrosion. The single head design eliminates the need for cumbersome spurge pipes.

FORBES Marshall brings to you the Automatic Pumping Trap - the world's smallest condensate drainage system that works under all the load conditions, even vacuum. It's compact design makes it convenient to install within 200 mm of the installation head. The Automatic Pumping Trap is fully mechanical with no requirement for electrical power, pnuematic supply, motors or level switches.  What do you mean by Stall ?  Stall is the reduction or the cessation of condensate flow from the steam space, and occurs when the pressure in the steam space is equal to, or less than, the total backpressure imposed on the steam trap.

One FORBES Strainer upstream of every trap, control valve, and flowmeter can save you a bundle in annual maintenance and wear & tear costs. Available in Y or T type designs, our Strainers remove suspended grit from steam and condensate that would otherwise damage your downstream equipments with no additional pressure drop.  FIG 12 Strainer The FIG 12 Y-type Strainers with stainless steel screens have 0.8 mm diameter perforations as standard.
