Typical Spira-trol™ installation overview Cooling water Superheated steam supply The above overview shows a typical pressure reduction and desuperheating station installation including a pressure control valve, a temperature control valve and a desuperheater. Each ancillary component of this installation ensures the longevity and proper operation of the control valves and the desuperheater. The isolation valves ensure safety when maintenance of the system and products are required. A strainer should always be installed upstream of a control valve to protect its internals from any potential...

Did you know? Cavitation is a dynamic process that can cause metal erosion, and even major mechanical failure in extreme cases. When the pressure in a liquid flow drops below a certain point, bubbles of vapour can form. Then, as the flow pressure recovers further downstream of the valve trim, these bubbles implode and collapse back into liquid state. This releases energy that can produce wear on adjacent metal components. Select a valve characteristic to complement your application Soft Seat Insert vs Soft Plug Flow Characteristics turbulent region of the flow. This will lead to leakages, •...
