Frequently Asked Questions
What are your customer service hours?
8am – 5pm, Monday through Friday.
Do you calibrate the valve electronics after performing a mechanical repair?
Yes. We ensure that LVDT’s are tuned and then bench-tested. Our test stand confirms that the command signal provides flow/pressure outputs within specification.
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.
Where do I go to submit a repair request?
Click Request a Repair and fill out the form at performanceservo.com/request-a-repair.
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.
Who pays for shipping?
Inbound and outbound shipping costs are a customer responsibility unless other arrangements are made. Performance Servo can initiate UPS/FedEx labels for customers if we know the weight and dimensions; shipping costs are recuperated on the Evaluation Quotation.
What payment methods do you accept?
Purchase order, credit card, ACH transfer, or PayPal.
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 I send my component in even if I’m not sure it can be repaired?
Yes. We evaluate components every day that customers are uncertain about. After inspection, we’ll let you know whether repair is possible and provide recommendations before any work begins. If it cannot be repaired, we’ll do our best to give you a quote for a new replacement component.
