May 2013
Figure 1. Type 1290 Vapor Recovery Valve
Features
Quick-Change Trim Package — Tested trim
Easy In-Line Maintenance — Top-entry design
reduces maintenance time and manpower requirements; trim parts can be inspected, cleaned, and replaced without removing the body from the line.
In-Service Travel Inspection — Standard travel
indicator assembly with protective cover permits periodic inspection of plug travel without removing regulator from service.
High Accuracy — Total proportional band of
0.25-inch w.c. / 0.62 mbar or less at lower set pressures.
Proven Technology — Time-proven regulator
technology has been adapted to meet the
speci c requirements of vapor recovery
(depadding) applications.
Introduction
The Type 1290 vapor recovery regulator controls vessel
blanketing gas pressure when the vessel is being  lled with  uid or when ambient temperature causes the vapor
gas to expand. The system monitors the increasing blanket pressure and throttles open to pass excess blanketing gas into a vapor disposal or reclamation system thus controlling the desired set pressure of the vessel.
The vapor recovery regulator is not intended to
be used as an ASME certi ed relief device for
overpressure protection. It is to be used as part of
the gas blanketing system to control the out ow of
blanketing gas under normal conditions and to collect vessel vapors for the vapor disposal or reclamation system. You should provide alternate methods of emergency overpressure protection per the American Petroleum Institute Standard 2000 (API 2000).
The vapor recovery regulator responds to any changes in the blanket gas pressure and throttles open or
closed to control the  ow of the blanket gas out of the
vessel. A vacuum source on the outlet of the regulator
is usually necessary to ensure  ow of low pressure

Note
The Type 1290 Vapor Recovery Regulator is not intended to be used as an ASME
certied relief device for overpressure
protection. It is to be used as part of the gas blanketing system to control the
outow of blanketing gas under normal
conditions and to collect vessel vapors for the vapor recovery system. You should provide alternate methods of emergency overpressure protection.
The Type 1290 vapor recovery regulator responds to any changes in the blanket gas pressure and throttles
open or closed to control the ow of the blanket gas
out of the vessel. A vacuum source on the outlet of
the regulator is usually necessary to ensure ow of low
pressure blanket gas out of the vessel into a vapor

recovery system. The higher the vacuum pressure of
the vacuum source, the higher the ow capacity of the
vapor recovery regulator.
The pressure of the blanket gas registers under the diaphragm of the pilot. A Type 95H regulator provides a constant loading pressure source to the Type 1098-EGR main valve actuator. When the pilot
is closed, the loading pressure lls both sides of the Type 1098 actuator through a xed restriction.
The Type 1098-EGR main valve spring keeps the main valve plug tightly shut off. When the vessel blanket gas pressure reaches the setting of the pilot spring, the pilot diaphragm moves, opening the pilot valve disk and exhausting some of the Type 1098-EGR’s actuator loading pressure through
the pilot orice. This typically happens when the vessel is being lled with liquid.

The small xed restriction maintains a higher loading
pressure on the bottom of the Type 1098 actuator. The pressure differential across the main valve diaphragm moves the diaphragm upward causing the main valve
to open which allows the blanket gas to ow out to
the vapor recovery system vacuum source, hence controlling the vessel blanket pressure.
When the vessel blanket gas pressure begins to stabilize, the pilot spring throttles the pilot disk closed. This allows
the loading pressure source to ll both sides of the Type 1098 actuator through the xed restriction. This
equalizes the pressure acting on the diaphragm, thus allowing the main valve spring to close the main valve plug.
Sizing Blanketing Systems
When sizing a gas vapor recovery regulator system, you must consider the volume of blanketing gas that must be
displaced from the vessel when either lling the vessel
with liquid (pump-in) or the expansion of vapors inside the vessel during atmospheric thermal heating.
Using the established procedures from American Petroleum Institute Standard 2000 (API 2000), determine
the ow rate for outbreathing.
1. Determine the ow rate of blanketing gas
displaced when liquid is being pumped into the vessel (see Table 6).
2. Determine the gas ow rate due to outbreathing caused by atmospheric thermal heating (see Table 7).
3. Add the requirements of 1 and 2 and select a vapor recovery regulator size based on total capacity required from Table 4.
Sample Sizing Problem for Vapor Recovery Applications:
Vessel Capacity . . . . . . . . . . . . . . . . . . . . 1000 barrels
Pump in Capacity . . . . . . . . . . . . . . . . . . 20 GPM / 75.7 lpm
Inlet Pressure Source . . . . . 60 psig / 4.1 bar nitrogen
Desired Blanket Setpoint . . . . 0.5-inch w.c. / 1 mbar
Desired Vapor Recovery Setpoint . . . 2-inches w.c. / 5 mbar Vapor Recovery Vacuum Source . . . 5-inches Hg / 169 mbar
Fluid . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Hexane
Boiling Point . . . . . . . . . . . . . . . . . . . . . . 155°F / 68°C
1. From Table 6 the desired air ow rate due to
pump in equals 20 GPM x 8.021 x 2 = 320 SCFH /
8.58 Nm3/h air.
2. From Table 7 the desired air ow rate = 1000 SCFH /
26.8 Nm3/h air due to thermal heating.
3. Total required ow rate = 1000 SCFH air +
320 SCFH = 1320 SCFH / 35.4 Nm3/h air. This converts to nitrogen requirements of 1340 SCFH /
35.9 Nm3/h.

Table 4 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

Installation
Install the regulator using a straight run of pipe the same size 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 regulators should be installed with the pilot spring case barrel pointed down.
