Frequently Asked Questions
Common signs that a proportional valve is failing?
Sluggish or delayed response, erratic positioning, pressure fluctuations.
Can you repair old or discontinued valves?
We can repair old or discontinued valves if we’re able to get the necessary components and diagnostic software.
Can you repair onboard electronics (OBE) directly on the valve?
Yes. We can repair or replace damaged electronic componentry on PCB’s such as transistors, LVDT’s, MOSFET’s, solenoids, and we do complete cleaning. We inspect and repair damaged solder joints.
Can you source original OEM parts, or do you use aftermarket?
We use both OEM and aftermarket parts. We will use aftermarket parts to improve performance and longevity for items such as ambient heat and vibration.
Will I receive tracking information when my repair ships?
Yes. When your item ships, the invoice is sent along with the tracking number.
Do I need to provide a purchase order before the repair can begin?
Yes, we need a purchase order or partial payment before we apply the cost to the repair.
What will my evaluation report tell me?
We will tell you if the valve and its components can be repaired or replaced to restore the valve to original specifications. We will evaluate the following when applicable: Torque Motor, Nozzle Flapper, Spool and Body Assembly, Flexure Tube, seals, Electrical Connectors, Wiring, Amplifier Cards and componentry, LVDT, Filters, Poppets, and Seats.
Do I need to provide approval before you begin repairs?
Yes. After evaluating your component, we provide a repair quotation. No repair work is performed until you approve the quote with a purchase order.
What is your typical turnaround time for repairs?
For standard level repairs, our turnaround time is 2 weeks from receipt of the damaged valve.
How do I request a repair quote?
You can request a quote by completing our online quote request form or by contacting our team directly. Provide as much information as possible about your component, including the manufacturer, model number, and any symptoms you’ve observed. This helps us provide the most accurate response.
Do I need to know the exact part number before requesting a quote?
No, although it is useful. If you don’t have the complete part number, send us any information available, including photos of the nameplate or component. Our team can often help identify the unit.
Can you ship repaired components internationally?
Yes. We’ll need contact information about the recipient. Customs requires a Commercial Invoice, along with a packing list and Bill of Lading detailing shipping terms and routing. An HS/HTS code and ECCN (Export Control Classification) are often required as well.
Do I need to send an electronic amplifier card with the valve for evaluation?
Yes, we highly recommend sending the on-board electronics along with the valve. The valve functions with the amplifier card, so it is required for us to have the original amplifier card.
