Delta "B"

Steam Traps

Unmatched Guarantee: No Live Steam Loss for up to 3 Years! Save Energy - Reduce Greenhouse Emmissions

Unique Principle of Operation:

The Bestobell Delta B use of a combination of thermostatic and thermodynamic forces results in a modulating operation and wide rangeability. The valve is constantly self adjusting to match the changes in the process conditions, while all the time maintaining a water seal at the valve, reducing wear and eliminating life steam loss.

The multiple orifice design of the valve works much like a control valve, varying the capacity by adjusting the orifice area instead of simply increasing the on/off cycling rate. This not only reduces mechanical valve/seat wear, but also provides for cold start up capacities that are 7 to 10 times the rated hot running capacity. This allows the trap to be properly sized to the operating conditions instead of having to apply questionable safety factors to handle start up loads and ending up with a trap too large for the process conditions.

The single blade bi-metal design is unaffected by dirt. The trap will not be damaged by water hammer as the pressure wave only increases the opening force, allowing the potentially damaging force to be dissipated.

"D" Series Drip and Small Heating Service Traps

"D" series drip traps are designed for mains drainage and low capacity space heating applications. Typically these applications have low and steady condensate loads and stable operating pressure, but where no condensate back up can be tolerated.

The internal valve design features a low gain thus providing fine control for the minor fluctuations in load that may occur.

"G" series drip traps are designed for general heating and process applications applications. Typically these applications can have significant variances in operating loads and fluctuating operating pressures, and no condensate back up can be tolerated.

The internal valve design features a high gain thus providing quick response to rapid changes in operating load.

The "M" models feature an intermediate load capacity for applications that are not satisfied my either the "D" or "G" series models.

"T" Series Tracing Service Traps

"T" series Tracing traps are similar to the "D" series traps in that they are designed for applications with low, steady condensate loads and steady pressures. The difference is that the "T" series allow sub-cooling of the condensate to make use of the sensible heat of the condensate.

The internal valve design features a low gain thus providing fine control for the minor fluctuations in load that may occur.

Magnum Series Ultra High Capacity Traps

Magnum traps feature multiple Delta "B" elements contained in a single fabricated body.

Up to 18 elements can be fitted into a single body and capacities to 150,000 lbs/hr can be accommodated.

They are suitable for pressures to 320 psig.

Maintainable Body Design

There are two maintainable body designs: a full sized design which incorporates a "Y" strainer, and a compact design (used only on the DM12 and TM22) which incorporates a basket strainer. Both are constructed from forged carbon steel and feature stainless internal components.

The full sized body internals have a larger valve orifice to better accommodate the the passing of dirt and scale which might get through the strainer. The "Y" strainer is superior to the basket strainer as it incorporates a dirt pocket in which to collect the dirt away from the operating element. Further, by fitting a valve to the strainer cap, it is possible to blow down the strainer periodically without having to interrupt the steam service.

The compact design was introduced to replace disc traps by having the same face to face dimensions. It should only be considered only when a clean system can be assured as the valve is smaller and has a reduced dirt handling capability.

Universal Mount Design

The Universal Mount facilitates ease of maintenance and simplifies retrofit when another manufacturer's (Sarco, Armstrong, etc) universal pipe piece is installed.

The design effectively removes the trap from the pipe work by placing it on an in-pipe connection piece. The trap can be removed from the system without having to break into the pipe work which can be time consuming and costly.

An integral blow-down assembly is provided with the pipe piece.

Sealed Body Design

The sealed body was designed initially for large refinery/chemical facilities in mind, where thousands of traps are employed on drip and tracing applications. Key advantages of the sealed design are smaller size, lower cost and no gaskets to leak, thus reducing maintenance. It also eliminates the potential that someone may try to repair it, when it would be cheaper to replace, thus saving thousands of man-hours in large plants.

SteamTector

Finding large steam leaks is easy. The difficulty comes in finding the traps that are starting to leak before they cost you a lot in wasted heat.

The SteamTector is an application specific ultrasonic leak detector tuned to be most sensitive to the frequency generated by small steam leaks through valves and traps
