We supply MOOG servo valves D633-308B and D633-313B. Genuine MOOG products and systems are suitable for many applications. Manufacturers, machine operators, and plant operators worldwide trust the efficiency, precision, and robustness of MOOG products.
MOOG products save energy, increase productivity, and significantly reduce operating costs—whether standardized or customized, they are suitable for a wide range of industrial applications. The MOOG D633 and D634 series servo valves are direct-drive (DDV) valves with electrically operated closed-loop spool position control.
These valves are throttle valves for 3-way, 4-way, and 2x2-way applications. They are suitable for electro-hydraulic position, speed, pressure, or force control systems, including those with high dynamic response requirements.
The spool drive is a permanent magnet linear force motor that actively pushes the spool to the center position in both directions from a spring.
This is an advantage compared to a proportional solenoid with a single force, which is only directional. Closed-loop spool position control and pulse width modulation (PWM) drive electronics are integrated into the valve.
are as follows: ---Direct drive by a linear force motor: no pilot stage required ---Linear force motor with a high output range (improving operating limits): no flow limitation ---Direct drive design: dynamic performance is pressure-independent ---Low current consumption when at or near hydraulic zero ---Valve spool is in the.

Plain language sourcing guide for MOOG servo valves D633-308B and D633-313B
Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.
Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.
Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.
If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.
Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.
Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.
Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.
Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.
For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.
For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.
For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
