Comeval Valve Systems – Technical profile of a valve and flow control equipment manufacturer

Comeval Valve Systems is a Spanish valve manufacturer founded in 1975. It became part of the ARI Group in 2011 and offers products for control, isolation, safety and steam trapping of liquid and gaseous media.

The official Comeval product categories include safety valves, control valves, air valves and anti-surge tanks, steam trapping and specialities, piping accessories, systems and energy-saving equipment.

Main technical areas include:

  • industrial isolation valves,
  • control valves,
  • safety valves,
  • air valves,
  • steam traps,
  • pipeline accessories,
  • energy-saving systems,
  • water and process technology components.

Control valves are used for modulating flow, pressure or temperature. Selection requires Kv calculation, pressure drop, fluid, temperature, leakage class, actuator type and fail position.

Safety valves are used for overpressure protection and must be sized according to the relief case, not line size. Required data include set pressure, required relieving capacity, medium, temperature and back pressure.

Air valves and anti-surge equipment are used in water networks to manage entrapped air, vacuum and transient conditions. Their selection depends on pipeline profile, filling / emptying rates, surge analysis and installation point.

Steam trapping and specialities are selected according to condensate load, differential pressure, back pressure, start-up conditions and steam quality.

Comeval products are relevant for industrial engineers, water network engineers, steam specialists and building-services engineers requiring valve packages across control, safety, steam and utility systems.

Comeval’s products are distinguished by their reliability, durability, and high performance, meeting the needs of diverse industrial sectors.
