Best Practices for Installation of Safety Valves

A steam boiler must be fitted with a stop valve (also known as a crown valve) which isolates the steam boiler and its pressure from the process or plant. It is generally an angle pattern globe valve of the screw-down variety. Figure 3.7.3 shows a typical stop valve of this type.

The outlet of the safety valve is connected to a 6 mm internal diameter pipe, the end of which is held 12.7 mm below the surface of water contained in a suitable, transparent vessel. The number of bubbles discharged from this tube per minute is measured. For the majority of valves set below 70 bar g, the acceptance criteria is 20 bubbles per minute.

Steam Control Valve - Coulton

The typical mechanism to adjust the outlet pressure is through a balance of force adjustment between the steam pressure and the adjustment spring in the valve. The steam control valve is manufactured either by Non-piloted Acting Valve or Pilot-operated Acting Valve. The non-piloted adjustment spring applies downward force directly on the main valve.

These boiler valves consist of a plug which can either be in the shape of a cylinder or conical.The plug also consists of a through slit which remains in-line with the flow in the open condition. When the plug is rotated by 90 Deg., this slit becomes perpendicular to flow and valves get closed.
