Valve checklist

Careful planning and attention to details are key when selecting valves for both critical and non-critical applications. Whilst valves serve the purpose of controlling fluids / gases, there are also many other factors that need to be considered during the selection process


Valves are produced in numerous design types, materials and configurations..
Selecting the correct valve is important to ensure the most efficient, cost-effective and longlasting solution.

Between our employees, we have over 100 years of valve experience, and know what needs to be taken into consideration to find the right solution.


To help you through the valve selection process, we have developed a valve check list :

 

Function

 
  • Open / Close
  • Regulate or decrease pressure
  • Reversal
  • Control pressure


Valve types

  • Ball valves ( Ball, DBB , DIB )
  • Butterfly valves
  • Knife Gate valves
  • Check valves
  • Choke valves
  • Pressure safety valves
  • Globe valves

  • Electric
  • Hydraulic


Planning & Delivery
  • What are the delivery requirements ?
  • When do the valves need to be delivered by ?
  • Which supplier(s) can meet the delivery requirements ?

Documentation
  • What documentation is required to meet regulations ?
  • When do you require the documentation ?
  • Can the supplier provide correct documentation ?

Check that the supplier has the required qualifications.
  • Make sure that the supplier has all the required certificates
  • ISO 9002 / Norsok M650 / ATE X / PED etc.
