Valves are used in a wide variety of applications. All of these need to be ordered with great care before they can be used. Doing a bit of groundwork first can prevent a lot of problems.
Check Pressure and Temperature Ratings
Every industrial valve is rated for maximum operating pressure and temperature. Prior to ordering your valve, make sure you know the maximum operating parameters of your system, then ensure that the published rating of the industrial valve you are about to order is greater than the parameters of your system. Rating can vary dramatically between valve classes so be sure to check the data sheet for the specific valve you are interested in rather than assuming based on size of the valve.
Verify End Connections and Dimensions
The wrong end connections can mean that, despite the specification having been met, the valve won’t fit. Check if your application requires flanged, threaded or butt-welded connection. Then, using the relevant datasheet, check the size of the bore and the face-to-face dimensions for your particular application.
Confirm Material Compatibility
Check the Material of the Body and Seat of the Valve to Check if it will be Suitable for the Process Fluid that will be passing through the Valve. If the process fluid is corrosive check if the valve is made from Stainless Steel, Carbon Steel or Brass. Also check if the Operating Temperature of the process fluid will affect the performance of the Seals on the Valve. Also check if the specified valve complies with BS and ISO valve standards for Industrial and Commercial applications.
Inspect Existing Stock on Site
Inspect for stored valves for signs of deterioration, evidence of damage to the seals, and signs that the stem has seized. It is worthwhile to give stored valves a good once over for the possibility of repair instead of ordering new ones.
Confirm Supplier Lead Times
Lastly check lead times with your supplier. Even the most common sizes and materials of industrial and commercial valves can have long lead times for less common sizes and for specialist materials. More on Valve Stock can be found at https://orseal.com/.
You just save your time by checking necessary information before ordering required parts.
