#11 Regulator

Single Seat - Bronze Trim - Composition Disc

Valve Description ■

The Powers #11 Regulator is a self-actuating control valve

which automatically controls the temperature of a ﬂ uid

without the use of external power. Adjust the set point and

the rugged self-operating #11 Regulator controls the ﬂ ow

of heating medium (water or steam) to maintain a constant

temperature.

The instrument has a vapor pressure thermal system contain-

ing a thermally responsive ﬂ uid. This thermal system rapidly

senses temperature changes at the bulb and controls the

ﬂ ow of heating medium through the valve to maintain the

desired temperature. The thermal system features a two-ply

brass bellows with six reinforcing ribs on the bellows head

and thick capillary tubing walls to ensure long operating life.

The Powers #11 CD Regulator features:

• Tight shutoff when the valve is closed

• A valve stem of highly polished corrosion resistant grade

316L stainless steel to decrease friction and reduce

hysteresis

• An adjusting nut mounted on ball bearings and a removable

set point adjusting rod to ease set point adjustments

• A set point reference scale to aid temperature adjustments

Operation ■

A bulb is connected to a bellows containing a thermally

responsive ﬂ uid. The bulb is inserted into the ﬂ uid you are

trying to control (process ﬂ uid) to sense its temperature.

The Regulator set point is adjusted to allow sufﬁ cient ﬂ ow of

heating medium (water or steam) through the valve to keep

the process ﬂ uid at the desired temperature.

(A) When the termperature of the process ﬂ uid drops below

the set point, the temperature of the thermally responsive

liquid decreases, which decreases the vapor pressure in the

bulb/bellows. The force of the resulting vapor pressure is less

than the spring force, so the bellows contract and the spring

extends, which raises the valve plug up from its seat. This

increases the ﬂ ow of the heating medium (water or steam),

which raises the temperture of the process ﬂ uid.

(B) As the process ﬂ uid temperature increases toward or

beyond the desired set point, the temperature of the thermal-

ly responsive ﬂ uid in the bulb increases, which causes the

vapor pressure to increase. This expands the bellows, com-

presses the spring, and moves the valve plug down towards

its seat, to reduce or stop the ﬂ ow of the heating medium.
