To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices to prevent service conditions from
exceeding those limits.
Additionally, the pilot could be broken
off the main valve by physical damage,
causing personal injury and property
damage due to escaping liquid. To avoid
such injury and damage, install the
regulator in a safe location where it is
protected from physical damage.
Liquid pressure control systems should
be designed using good engineering
practices to eliminate quick starting or
stopping of the ow stream, which can
produce water hammer. .
1. Only personnel qualied through training and
experience should install, operate, and maintain
a Type 92W regulator. Before installation, make
sure that there is no damage to, or debris in, the
regulator. Also make sure that all tubing and piping
are clean and unobstructed.
