Emerson has introduced the Daniel V707 back pressure control valve, which features an adjustable spring that does not require diaphragms or pilots, making it ideal for the crude oil industry - especially for Lease Automatic Custody Transfer (LACT) skids.
Back pressure valves currently available in the marketplace use rubber diaphragms that are prone to wear, failure and leakage, and have pressure limits to operation. Alternative technologies such as gas loaded valves require the customer to maintain a nitrogen control system. In both cases, operators are required to integrate a second valve on the LACT skid as a check point. The new Daniel valve includes an integrated check valve for two in one functionality.
