Primary pressure: Steam pressure at the inlet of the pressure regulator.

Secondary pressure: Steam pressure at the outlet of the pressure regulator.

Minimum adjustable flow rate: Minimum flow that can be maintained at a constant pressure level.

Set pressure: Desired secondary pressure.

Rated flow rate: Maximum flow rate, at secondary pressure, that can be obtained within a given offset when the primary pressure is held constant.

Pressure rise: The increase in set pressure, following steam-using equipment shutdown by closing the inlet valve to the equipment.

Offset: Difference between actual secondary pressure and set pressure, when flow rate is increased from the minimum adjustable flow rate to the rated flow rate while primary pressure is held constant.

Above: The pressure and flow characteristic data prove stable valve performance: accurate pressure reduction is maintained even if flow varies. This test data was obtained by computer-controlled automated testing equipment.

Left: After setting the secondary pressure of 30 psig when the primary pressure is 45 psig the chart illustrates the variation of the secondary pressure when the primary pressure is increased to 150 psig.

Separation rate (%) is given as:

quantity of condensate discharged

x 100

quantity of incoming condensate

.....This combined with the pressure reducing

function of the valve, delivers virtually 100% dry steam downstream.
