When purchasing control valves today, you have to do more than just consider price and quality. Valves now come in many different designs, styles, materials, and targeted specialized use. It is increasingly becoming a daunting task to evaluate whether you are getting the right control valve for your project. However, there are some crucial questions you can always ask when purchasing control valves to ensure you get the right valve, which guarantees many years of service and trouble-free operation.
1. Ask about the components making up the valve
The different components making up your valve such as valve seats and sterns will certainly affect the life of your valve. Also ask about the material making up the valve’s body. Is it cast iron or ductile iron? Is the body coated? What is the grade of stainless steel used? What material are the external fasteners such as studs and bolts made of? Tip: Choose stainless steel fasteners to avoid rusting and ensure that nuts and bolts can be removed for maintenance even during the valve’s old age.
2. Ask the supplier if he or she fully understands your specific application
There is a very thin line between the right and wrong valve for a specific application. There also is always a chance that you can find a better valve for your specific application if you search further. Ask your supplier if he or she fully understands your valve application requirements and ask for a range of several valve suggestions to choose from.
3. Ask if the valves will require special tools for maintenance
A great valve for any application allows for easy maintenance. Ask the supplier if the valve can be maintained with the regular equipment in your tool kits or if specialized tools will be required.
4. Ask if your technicians will receive some factory-qualified training on the valves
Ask if your valve personnel will get factory-qualified training on the valves so as to prepare them for repair and maintenance services. This way, you will not have to rely on factory-deployed technicians in the event of an emergency with your systems.
5. Ask what type of warranty you will get on the valves
Make sure to ask about the warranty you will be offered. Is it factory-backed? Will the supplier/installer offer a workmanship warranty?
6. Ask to see if the valve meets industry standards
Ensure that the valves you are purchasing meet various industry standards by checking for third party accreditations. Accreditation assures that the valves have been built to the correct specifications.
7. Ask if changes can be made to the valves when need arises
Request to know how flexible the valves you are purchasing can be. Having valves that can easily adapt to your future expansion plans will make your transition process easier and cheaper down the road.
With these few questions, you can hardly go wrong when purchasing control valves.
