FAQ:

What is "Mechanical Null Adjustment"?

The mechanical null adjustment allows you to calibrate the valve's flow null (the spool position where no flow passes to the actuator when the input signal is zero) independently of other system parameters. This is done by rotating an eccentric bushing retainer pin with an Allen wrench, which can adjust the flow null by at least ±20% . This adjustment should be performed if system components are drifting or stuck in a hardover position .

. Where can I find repair services?

Moog does not authorize any facilities other than Moog or its subsidiaries to repair its servovalves. Repair by an independent, unauthorized facility will void the Moog warranty and could lead to performance degradation or safety issues. It is recommended to contact Moog directly to locate the nearest authorized repair facility .

. What are the typical product series and their applications?

Moog offers a wide range of servo and proportional valves. The D660 series (including D661 to D665) are servo-proportional control valves used for throttle-type flow control in two, three, four, and five-way applications . They are suitable for high dynamic response requirements in position, speed, pressure, or force control systems. These valves find applications in industrial automation, aerospace, testing and simulation, mechanical manufacturing, and more .
