Principle of Operation
Type 114PL High-pressure Reducing and Low-flow
System uses inlet pressure as the operating medium,
which is reduced through the spring-loaded pilot to
load the pneumatic-loaded pilots’ cases.
When the outlet pressure (P
d
) drops, the motorization
pressure (P
m
) opens more the nozzles in the
pneumatic-loaded pilots supplying the required flow to
the downstream system.
Any excess motorization pressure on the actuator
diaphragm escapes downstream through the bleed
restriction in the pilot.
When the gas demand in the downstream system has
been satisfied, the outlet pressure (P
d
) increases. In
this case, the outlet pressure closes the nozzles in the
pneumatic-loaded pilots until reach the setting value.
Installation
▲
WARNING
Personal injury or equipment damage,
due to bursting of pressure-containing
parts may result if this system is
overpressured or is installed where
service conditions could exceed the
limits given in the characteristics
section and on the appropriate
nameplate or where conditions exceed
any rating of the adjacent piping or
piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices to prevent service conditions
from exceeding those limits. Also, be
sure that installation is in compliance
with all applicable code and regulations.
Physical damage to the system can
break the pilot off the main valve,
causing personal injury and property
damage due to bursting of pressure-
containing parts. To avoid such injury
and damage, install the regulator in a
safe location. Only personnel qualified
through training and experience should
install, operate and maintain a regulator.
Before installation, make sure that there
is no damage to or debris in the system.
