Moog receives certification according to NEC 505

16 May 2019

Moog has received certification according to NEC 505 from FM Approvals for its full line of Digital Control Servo Valve products including the D636K to D639K, D671K to D675K and D941K to D945K Series, which customers can use with onshore and offshore oil and gas drill rigs. This product family also holds the ATEX and IECEx certifications.

Moog Explosion-Proof Digital Control Servo and Proportional Valves provide intelligent closed-loop motion control and optimize equipment functionality. The product family includes designs for flow control and pressure and flow control; Moog also has Axis Control Versions available. The Pressure and Flow Control Valves have a pressure transducer integrated into the valve to access the optimum sampling position. On-board electronics monitor the valves in internal closed-loop control to create pressure control. This capability often enables the user to use one valve instead of two, (i.e., defining minimum or maximum pressure, while controlling flow or controlling pressure with defined limits to the flow) offering customers flexibility and cost-saving.

Customers can use the Explosion-Proof Moog Digital Control Servo and Proportional Valves for a range of applications in offshore and onshore oil and gas exploration and production.

This product family provides CAN/Canopen, EtherCat and PROFIBUS fieldbus connections, which equipment builders and operators find easier for controlling drilling machinery at a high-performance level in potentially explosive environments.

The newly certified D636K to D639K, D671K to D675K and D941K to D945K Series Digital Control Servo and Proportional Valves are also suitable for applications in potentially hazardous environments like power generation and chemical processing.
