Figure 1. Type Y696 Vapor Recovery Regulator

Features

• Simplicity—Direct-operated, straight forward stem and
lever design minimizes the number of parts while
providing excellent regulation of pressure.

• Precision Control—Large diaphragm area provides very
accurate throttling control at low set pressures.

• Rugged Construction—Heavy duty castings and
internal parts are designed to lessen vibration and shock.

• Ease of Inspection and Maintenance—The union nut
connection permits maintenance or inspection of critical
parts without removing the body from the line.

• Variety of Construction Materials—Body and lower
casing are available in cast iron, steel, stainless steel,

or Hastelloy® C. Spring case is available in cast iron,
steel, or stainless steel. Trim is available in stainless
steel or Hastelloy® C.

Introduction

The Accu-Pressure™ Type Y696 is a direct-operated vapor
recovery regulator with internal registration, requiring no
downstream control line. This regulator is used to sense
an increase vessel pressure and vent excessive internal
tank pressure to an appropriate vapor recovery disposal
or reclamation system. However, inlet pressures, outlet
pressures, and other performance characteristics vary
according to construction.

Hastelloy® C is a mark owned by Haynes Internatio nal, Inc.

Principle of Operation

The Type Y696 vapor recovery regulator is used to maintain
a constant blanket (inlet) pressure or vessel pressure with
the outlet owing to a system whose pressure is lower than
that at the inlet.

When vessel pressure increases above the setpoint of the
regulator due to pumping in or thermal heating, the force
of the control spring is overcome by pressure acting on the
diaphragm. This moves the disk away from the orice allowing
gas to ow from the vessel to the vapor recovery system.

As vessel pressure is reduced, the force of the control
spring causes the disk to move toward the orice
decreasing the ow of gas out of the vessel. As vessel
pressure drops below the setpoint of the regulator, the disk
will seat against the orice shutting off the ow of gas.

Sizing Vapor Recovery Systems

To determine the capacity required, you must consider the
amount of blanketing gas that must be displaced from the
tank when either lling the vessel with liquid (pump-in) or the
expansion of tank vapors during atmospheric thermal heating.

Using the established procedures from American Petroleum
Institute Standard 2000 (API 2000), determine the required
ow rate for outbreathing.

1. Determine the ow rate of blanketing gas displaced when

liquid is being pumped in (see Table 6).

2. Determine the gas ow rate due to “outbreathing”

caused by atmospheric thermal heating (see Table 5).

3. Add the requirements of 1 and 2 and select a vapor

recovery regulator size based on total capacity required
from Table 7.

2. From Table 5 the desired air ow rate = 4000 SCFH

(107 Nm3/h) air due to thermal heating.

3. Total required ow rate = 4400 SCFH (118 Nm3/h) air.

4400 SCFH (118 Nm3/h) converts to 4500 SCFH
(121 Nm3/h) nitrogen.

4. From Table 7, with a 2-inches w.c. (5 mbar), and an outlet

pressure of 5-inches Hg, an NPS 1-1/2 or 2 (DN 40 or 50)
body size would ow 5130 SCFH (137 Nm3/h) nitrogen.
This would satisfy the desired ow rate of 4500 SCFH
(121 Nm3/h) nitrogen.

Capacity Information

Table 7 gives typical nitrogen regulating capacities at
selected inlet pressures and outlet pressure settings. Flows
are in SCFH (at 60°F and 14.7 psia) and Nm3/h (at 0°C and
1,01325 bar) of 0.97 specic gravity nitrogen. For gases of
other specic gravities, multiply the given SCFH capacity
of nitrogen by 0.985, and divide by the square root of the
appropriate specic gravity of the gas required. Then, if
capacity is desired in Nm3/h, multiply SCFH by 0.0268.

Installation

Install the regulator using a straight run of pipe the same
size as or larger than the regulator body. Flow through the
regulator body is indicated by the ow arrow cast, stamped
or riveted on the body. If a block valve is required, install
a full ow valve between the regulator and the blanketed
vessel. For proper operation at low setpoint ranges, the
Type Y696 regulators should be installed with the spring
case barrel pointed down.
