Water Pressure Reducing Valves

There are two types of water pressure reducing valves: pilot-operated and direct-acting. Types of WPRVs Pilot-operated valves have a sensing control pilot and main valve in one unit. These valves are typically used in commercial appli-cations such as schools, hotels and hospitals, as well as in industrial and municipal applica-tions and installa-

Cross Reference - Emerson Electric

Gas flow to the pilot burner is controlled by a safety valve which is manually operated and held in by current generated from a thermocouple placed in the pilot flame. When the thermostat calls for heat the main valve is energized. Proven Pilot The thermostat calls for heat and simultaneously energizes the pilot valve and the Proven Pilot control.

According to Henry’s Law, when the pressure of . a gas over a liquid is decreased, the amount of . gas dissolved in that liquid will also decrease. One of the best practical . demonstrations of this law is offered by opening a soft drink. When the cap is removed from the bottle, gas is heard escaping, and bubbles can be seen forming in the ...
