Product Description

EFB/ERB EQUALIZING CHECK VALVE

INTRODUCTION

The Equalizing Check Valves prevent downward flow while allowing upward flow through the device. These wireline retrievable check valves are run and landed in components with Model F or R profiles. They are utilized to test tubing, set hydraulic packers and prevent fluids from entering the formation during intermitted gas lift installation.

EFB Equalizing Check Valves are complete units (not flow control bottoms) that land on the top no-go shoulder of a Model F Landing Nipple. The no-go shoulder prevents downward movement, but the valves are not locked into the nipple to prevent upward movement. The check valve is equalized by shifting open large bypass ports during retrieval operations.

ERB Equalizing Check Valves are complete units (not flow control bottoms) that land on the bottom no-go shoulder of a Model R Landing Nipple. The no-go shoulder prevents downward movement, but the valves are not locked into the nipple to prevent upward movement. The check valve is equalized by shifting open large bypass ports during retrieval operations.
