Features

• Quick-Change Trim Package — Tested trim

packages can be ordered and stocked ahead of time for fast replacement.

• 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
