November 22, 2019 – Emerson has introduced the Daniel V707 back pressure control valve, which features an adjustable spring that does not require diaphragms or pilots, making it suitable 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 Daniel valve includes an integrated check valve for two in one functionality.
The V707 is based on the trusted Daniel 700 Series valve design which includes a metal to metal seat and protected O-rings to handle harsh crude oil conditions. While users have to stop operations to maintain and replace diaphragm valves, the V707 will ensure minimum maintenance.
