SIDEPOCKET MANDRELS, OVAL BODY
D and F SERIES SIDE POCKET MANDRELS
The OPTI-FLOW WP Series gas lift valves are retrievable, injection pressure operated valves with a nitrogen charged dome and bellows configuration. Since the charge pressure above the bellows is affected by temperature, it is important to use accurate operating depth temperature information when calculating the set pressure. The nitrogen dome pressure is preset at a reference temperature and corrected to an operating depth temperature for the desired application. The valve is held on seat by the downward force of the nitrogen charge inside the bellows.
