٢٠ يناير Electric actuated fail-safe control valves
Mechanical fail-safe solutions exist for electric driven valves, however mainly for on-off applications. For control valves often the only solution is ‘stay-put’ upon electric power failure since for mechanical fail-safe the electric actuator shall overcome both the thrust to move the valve and the spring force.
٧ يناير Near zero flaring with HIPPS
The aim to achieve zero routine flaring by 2030 is initiated with the Global Gas Flaring Reduction Partnership (GGFRP) of the Worldbank, supported by the UN’s Climate Initiatives Platform.
٢ ديسمبر Self-acting electric actuated valve
Mokveld delivered the first local pressure control loop with a pressure transmitter directly connected to the control valve in the Far East almost 10 years ago. A back-pressure control application, with a conventional gas driven actuator.
