Manufacturer’s recommend that control valves and related pilot systems be inspected and tested every year and rebuilt every 5 years
Our yearly maintenance program includes all this and more!
In our yearly maintenance program we work with you to identify a the valves to rebuild each year in and follow it up each successive year with an inspection so that all your valves are inspected and rebuilt on a regular schedule meeting manufacturer recommendations and guidelines. Participating in a yearly maintenance program insures minimal downtime for service work and reduces your risk for emergency repair services during the year.
The Yearly Maintenance Program consists of:
- Detailed valve inventory and System Analysis
- Rebuild of your existing Valves
- Follow-up inspections
Valve inventory and System Analysis
We begin your yearly maintenance program with us is to schedule a valve inventory and system analysis.
- Document each valve in your system for your reference
- Here we identify a preventative maintenance program to prolong the useful life of your existing valves.
- During our tour of your system we can identify problems or potential problems to prevent expensive emergency repairs and costly down time.
- Provide you with documentation which will helpful for you for your yearly budgeting.
Valve Rebuilds
Once we’ve formulated a maintenance plan for your system, we may perform a rebuild of some of your valves.
This work includes:
- Replace all rubber parts in the main valve and related pilots.
- All metal parts are cleaned and inspected. Metal parts are only replaced when needed and with your prior approval.
- Recalibrate the valve and pilots to their previous setting or to the new ones you specify. Set points are recorded for your reference.
- Valve restarted and fully tested.
Follow-up Inspection
Each proceeding year, we will conduct a maintenance inspection of all the valves in the maintenance agreement.
Yearly maintenance inspections consist of the following:
- Diaphragm test – The valve will be tested by cycling the valve fully open and closed. This process will remove all build up on the stem and ensure the valve maintains a drip-tight seal between the disk and seat.
- Inspect strainers – All strainers are inspected and cleaned if necessary.
- Valve and pilot system set points are checked to insure proper calibration.
- Exercise the inlet and outlet gate valves.
