Spirax Spiratec steam trap monitor R2T with sensor chamber.
A leaking trap is a liability. In an average process industry, one bad trap can lose up to 9 tonnes of steam per year! (subject to steam and trap parameters) We designed the Spirax Spiratec system to monitor every trap in your plant, so you can be sure that leaks are pin-pointed immediately. Sensors mounted upstream from each trap can detect trap failures in both the open (live steam passing) and closed (water logging) position. Signals from the sensors can be monitored either with a hand-held indicator or through the several Spiratec online steam trap monitors.

Spiratec R 2 T
The Spiratec R 2 T is an automatic steam trap monitor for two steam traps. Remotely mounted, it continuously scans electronically up to 2 Spiratec Sensor Chambers and indicates when steam wasteage or waterlogging occurs at any of the traps being monitored.

The R 2 T which is continuously operating, will indicate at a glance that either all the traps are operating correctly, or that there is a failure of any particular identified trap or traps.

In addition to the trap performance, it also continuously monitors and displays the temperature at which the condensate is being removed from the steam space, giving valuable information about process efficiency.

R2A is the same product as R2T but available with Audible Alarm facility when the trap fails.

Forbes Marshall Piston valves & Rotary Joints.
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 leak proof 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.

FEATURES :
Larger effective sealing area :
Leak proof isolation - Class 6 shut off achieved.
Durability - Piston unexposed to media
Absence of Gland & Seat
Maintenance friendly - Uniform sealing rings on both the sides & maintenance can be done without removing the Piston Valve from the pipe line. (On-line Maintenance)

Deaerator head, Insulation Jacket.
Fitted on your feedtank, the Spirax 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 sparge pipes.

Pressure Reducing Station, Flow Meters, TD3S
Since the majority of pressure reducing valve problems are caused by the presence of moisture or dirt, a Moisture Separator and Strainer with fine mesh screen are fitted before the valve. The strainer is fitted on its side to prevent the body filling with water and to ensure that the full area of the screen is effective. All upstream and downstream pipework and fittings must be adequately sized to ensure that the only appreciable pressure drop occurs across the reducing valve itself.

''Spirax'' Pressure Reducing Station (PRS) is the solution for your Steam Pressure Management needs.

Meter every unit of steam, generated or distributed. After generating the steam is distributed to various sections from the main steam pipe/heater. But it is necessary to know the exact steam consumption in the individual departments within the production plant or in the individual production lines. Any indicated increase in steam consumption above the accepted norm for a given production rate will indicate some inefficiency developing in that section of steam using production plant, which can be investigated and remedied. The other perhaps obvious reason for the monitoring of steam consumption is the ability to operate accurate cost accounting for a specific product line. The steam flow meter Accuflo is the perfect tool for providing exact information about the steam consumption and steam quality.

Spirax Sarco Vaccum breaker (VB14 / VB 21), Steam Injector, APT-10/14/HC
The VB 14 is a small purpose designed vacuum breaker for general purpose applications on condensing vapour(steam) or liquid systems.
Spirax Steam Injectors are available in three sizes to cover most of direct steam injection requirements. They ensure quiet but vigorous mixing of steam and feedwater to drive off the dissolved oxygen content down to approximately 2 ppm. This action minimises the amount of oxygen scavenging chemicals required. The temperature of the feedwater is maintained at a high steady level for smooth boiler operation.

Spirax Sarco steam injectors use steam to raise the temperature of water or other liquids. The injector draws in cold liquid, mixes it with steam inside the injector and distributes the heated liquid in the tank. In many applications the circulation induced by the injector is an advantage ensuring thorough mixing and avoiding temperature stratification.
