FKDY hydraulic BOP control systems with automatic accumulator charging, four control circuits and an emergency manual pump.
Share your application and required configuration for a project-specific quotation.
Product overview
The FKDY hydraulic control system supplies hydraulic power to BOPs, wellhead hydraulic valves and hydraulic clamping devices. The FKDY200-4 reference configuration uses a reservoir, five accumulators, an electric triplex pump, a manual pump and a four-circuit control manifold.
Three-position, four-way rotary valves control the connected hydraulic functions, while pressure sensing supports monitoring and automatic pump start/stop. The manual pump provides an emergency pumping arrangement. Supply the circuit schematic, actuator requirements and available utilities to confirm the equipment configuration.
Automatic accumulator charging
Four independent hydraulic control circuits
Emergency manual pump
Accumulator and system pressure monitoring
Integrated rotary-valve control manifold

Before you enquire
What does the FKDY200-4 reference configuration include?+
The catalog configuration includes a 400 L reservoir, five 40 L accumulators, a 7.5 kW electric pump, a manual pump and four control circuits. Confirm the final scope in the quotation.
Is 31.5 MPa the system operating pressure?+
No. The catalog lists 31.5 MPa for the accumulator components and 21 MPa for the hydraulic system working pressure. Component ratings do not raise the complete system rating.
How are control settings and enclosure protection selected?+
Specify the required pressure-control settings, site conditions and enclosure protection in the RFQ. These items are confirmed against the offered configuration and its documentation.
