When steam loads fluctuate rapidly or when a sudden high steam demand occurs on any steam system, instability due to low steam pressure can be the result. The Clayton Back Pressure Regulator is designed to prevent this by ensuring that the pressure in the steam generator does not fall below a preset limit.

THE CLAYTON BACK PRESSURE REGULATING VALVE
is
a self-operated steam pressure regulator which is mounted in the steam
outlet line from the Clayton Steam Generator. The valve taps it’s
actuating energy directly from the steam itself and ensures that a
minimum upstream pressure is maintained.
If the upstream pressure falls below the set point the valve will starts to close until the minimum desired pressure is achieved. The Clayton Back Pressure Regulating Valve is extremely reliable and versatile.
ADVANTAGES
A sudden drop in steam pressure is undesirable for several reason. In particular it can produce ‘flash steam’ and water carryover. However by controlling the minimum pressure, the steam generator system is maintained in a balanced condition at all times. An added benefit of using the regulator is that it allows faster heat up after initial start and faster recovery following a period of overload.
By providing stable operation of the steam system the Clayton Back Pressure Regulating Valve also gives additional protection to the helical water coil.
MULTIPLE STEAM GENERATORS
On multiple steam generator installations the Clayton Back Pressure Regulator will provide stable operation on start-up and during operation and will maintain the system in balance. On multiple installations separate regulators are required on each steam generator.
