Auto Trim High Pressure Boilers are used in all auto trim shops. Steam boilers are built to the highest safety.

Automatic Boiler Controllers automatically monitor and control the total dissolved solids present and prevents scaling within the boiler system. These controllers measure the solutions actual electrical conductivity.

Bellows pressure gauge is used to determine vapour pressure. This is calibrated on the basis of a U-shaped oil pressure gauge. These are made by forming thin-wall tubing. To obtain a reasonable fatigue life and motion that is more linear with pressure, a coil spring supplements the inherent spring rate of the bellows. These spring-loaded bellow gauges are generally used in pressure ranges having spans to 100 psi and to 1 in. Hg. This consists of an ash croft pressure gauge that is used for measuring low-pressure form 10 H2O to 10 psi.

Bimetallic Thermometer measures temperature by means of the differential thermal expansion of two metals. It is useful for alarm and over-temperature applications where extreme accuracy is not essential. It consists of two different metals (usually brass and iron) of different expansion coefficients rolled together, and usually formed into a spiral or helix. The bimetallic thermometer is usually the temperature-sensing part of the thermograph, an instrument that measures and records temperature. In a bimetallic thermometer differential expansion of bimetallic strips is used to indicate the temperature. It makes use of the coefficient of the linear expansion principle.

Blowdown tanks are used as an alternative system for cooling the bottom boiler blowdown. The function of a blowdown tank allows undesirable discharge from the boiler that is to be discharged directly out of the system. These large tanks retain the blowdown water volume from one blow after the flash steam, which has been vented to the atmosphere and allow the water to cool down by natural convection over 6-12 hour period. The cooled water will be below 140 ° Fahrenheit when it is displaced by the next blowdown and forced out of the overflow drainpipe.

Boiler feedwater valves are designed for the pulp and paper industry. These valves control the boiler feedwater into existing boilers. The main valve has a special trim at low openings and cavitation control at large openings. It controls pressure drop across boiler level-regulator when boiler is fed by motor-driven centrifugal pump.
