24 " ( 600mm) Pump Control valves - Monterrey , Mexico


Project objective
  • Prevent water hammer during pump startup and shutoff.
  • Prevent returning flow (non-slam check feature) in case of power failure.

The challenge 

The pumping system requirements:

  • Replacing old, bulky piston actuated pump control valves at the site, thus reducing the operational costs and improving the performance of the system.
  • Protection against water hammer during start-up and shutoff procedures.
  • Preventing plug slamming while preforming fast emergency closure in case of power failure.
  • Achieving fast and slam free closure, in a low pressure-loss control valve. 

The solutions

To install 24" ( 600 mm), hydraulically operated, booster pump control valves, on 4 of the supply pumps to the municipal reservoirs in 2 different pump stations. Following rigorous tests against competing valves, the customer (Monterrey City which is Mexico's largest industrial city) chose Dorot's model
30-24-BC.
