Introduction
Features
Y600A Series direct-operated, spring-loaded
regulators provide economical pressure-reducing
control for a variety of residential, commercial, and
industrial applications.
  •  Precision Control at Low-Pressure Settings—t
The large diaphragm area provides more accurate t
control at low-pressure settings. The pitot tube t
of Types Y600A and Y600AR (Figure 2) regulators t
also creates a dynamic boost that helps provide t
greater capacity.
The large diaphragm area provides more accurate
control at low-pressure settings, and the pitot tube of
the Type Y600A or Y600AR regulator also creates a
dynamic boost that helps provide greater capacity.
  •  Tamper-Resistant Adjustment—The closing
cap and spring case (Figure 2) allow the t
installation of sealing wire to discourage or detect t
unauthorized adjustment of the pressure setting.
  •  Easy to Maintain—Trim parts can be replaced
without removing the regulator body from the
pipeline. A two-bolt connection between the body
and diaphragm casing simplifies disassembly
for maintenance.
