Introduction
  • asy Conversion Between Constructions—
E
Converts easily from the Type Y690A to the
Type Y690AM with two O-rings and one machine screw.
The Y690A Series self-contained, spring-loaded regulators
(Figure 1) provide economical pressure reducing control
in a variety of commercial and industrial applications.
The Y690A Series design is ideally suited to control gas
supply to in-plant processing equipment. The rugged
casings and sliding pusher post design withstand the full
150 psig / 10.3 bar inlet pressure at both the inlet and outlet
connections. The sliding pusher post design prevents
damage to internal parts if the downstream pressure
exceeds the setpoint. Because these regulators can
withstand the full inlet pressure, a downstream or internal
relief valve is not required to protect the downstream side of
the regulator.
  • our Gas Service Capability—For sour gas
S
applications, the Y690A Series regulators are available in
materials that comply with NACE International Standards
MR0175 and MR0103.
  • nlet Pressure Equals Outlet Pressure—Full

inlet pressure capability on the downstream side of
the regulator.
  • orrosion Resistance—Multiple regulator constructions
C
are available in a variety of materials for compatibility with
corrosive process gases.

  • ultiple Applications—The Y690A Series can be used
M
for a wide variety of gases including air, nitrogen, natural
gas, sour gas, butane, and propane.
