Product Description

  1. Lever Safety Valve :
    An all metallic demonstration model showing the valve seat, fulcrum and lever with adjustable weight.
  2. Spring Loaded Safety Valve :
    The demonstration model having two separate valves with one lever bearing loaded by a spring.
  3. Dead weight Safety Valve :
    The valve resting on the seat the top of an outlet pipe. The valve and pipe are covered by a case carrying weights hanging freely from the valve.
  4. Combined High Steam and Low Water Safety Valve :
    Safety valve blows off when the steam pressure exceeds the working pressure. This high steam to escape as water level falls too low. A properly constructed model fitted on suitable base.
  5. Water Gauge Model:
    An all metallic and properly constructed model. Upper and lower parts are with transparent inserts to make the interior construction visible and are connected by a hollow column. The unit is complete with cock and stuffing’s mounted on a polished wooden board.
  6. Stop Valve Hopkinson Type:
    The type of model has many advantages over ordinary design of junction stop valves. The construction and the method of operating the complicated model can be easily demonstrated with this all metallic section cut model.
  7. Feed Check Valve:
    All metallic section cut model. A good design of non return valve and arrangements for regulating by hand can be easily demonstrated with this all metallic section cut model.
  8. Steam Injector:
    This cutway demonstration model is to understand the system of feeding a boiler with water by direct use of steam. Showing water and steam inlet, overflow valve and overflow outlet. The central screw cut spindle carries valve and the upper end with handle. The steam cone is actuated by rotating the handle. It is fitted on 45 cm high wooden board.
  9. Pressure Gauge:
    Bourdon’s type. Large size, open construction model for explaining the principle. Mounted on cast iron base with air nozzle. It is provided with transparent graduated dial to see the inner-constructional details of the Bourdon’s tube.
  10. Pressure Gauge:
    Bourdon’s type. Large size, open construction model for explaining the principle. Mounted on cast iron base with air nozzle. It is provided with transparent graduated dial to see the inner-constructional details of the Bourdon’s tube. Size 50 mm dia.
  11. Blow Off Cock:
    An all metallic sectionised model mounted on cast iron base.
  12. Reducing Valve:
    The function of this valve is to maintain a constant reduced pressure on the engine side while the higher pressure on the boiler side may be variable. It is a large size section cut model, to make the students understand its working.
  13. Fusible Plugs:
    A set of three, section cut & properly constructed models mounted on polished wooden base.
  14. Anti-Priming Pipe:
    The model is complete with seating of junction valve. The perforated pipe is about 30 cm long and 4 cm in diameter.
  15. Expansion Steam Trap:
    In this system the advantage is taken of the expansion of materials on heating. The unit is all metallic, section cut, mounted on 40 cm high wooden board.
  16. Float Steam Trap:
    This type is intended to separate water by a float which is raised when it accumulates in the trap, thus opening a valve and permitting water to escape. The model is all metallic, section cut and mounted on cast iron base.
  17. Green Economiser:
    It is an all metallic demonstration model to understand the working of a feed water heater. Complete with safety valve, scrapers, chains and pulleys. Flue passage i.e. all brick work is shown in wood work and the model is so dissectible that the inner construction can be seen clearly. Approximately 45x30x25 cm.
  18. Sudgen Super Heater:
    Flue passage and all brick work is shown in wood work and the model is selected in such a manner that an inner section view can be studied. The overall size is about 30x30x20 cm.
