Introduction

Scope of the Manual

This instruction manual provides installation, startup,

maintenance, and parts ordering information for the

Type Y692 Low-Pressure Gas Blanketing Regulator.

Product Description

The Accu-Pressure™ Type Y692 Gas Blanketing

Regulator (Figure 1) is a pressure reducing direct-

operated regulator with internal registration or external

pressure registration. It is used for accurate pressure

control on very low-pressure blanketing systems.

Blanketing with low-pressure gas helps prevent

corrosion, helps control emissions from the blanketed

product and helps protect against any contamination to

the blanketed product by atmospheric conditions.

The regulator will maintain a positive vessel

pressure reducing the possibility of vessel wall

collapse. The Type Y692 is available in NPS 1-1/2

and 2 (DN 40 and 50) body sizes.

Type Y692 with external pressure registration

regulators have a stem seal with O-rings and a

1/2 NPT control line connection in the diaphragm

case. The control line can be used to more accurately

control the pressure in the tank if the regulator is

mounted an extended distance from the control point.

The stem seal separates the body outlet pressure from

the diaphragm case.

Specications

The Specications section lists specications for

Type Y692 Gas Blanketing Regulator. Specications

for a given regulator as it originally comes from the

factory are stamped on the spring case nameplate.
