About Us

Mokveld Valves BV from Gouda in The Netherlands, is a leading supplier of Engineered Valve Solutions for critical control and safety applications in Hydropower. High head energy dissipation (zero cavitation) for turbine or dam by-pass, penstock dewatering systems (drainage) and for mitigation of pressure transients (water-hammer).

Axial Control Valves

In some ways, the Mokveld Axial Control Valves are comparable to plunger (needle) valves, with the essential difference, that its multi-stage trim technology, completely eliminates cavitation. Heads can be over 1000 mwc (or 3300 fwc).

For pressure relief applications, the quick opening and precise control are of interest when switching between turbine to pump mode frequently, shortening transition time (PSH). Active Water Hammer Mitigation for stress reduction and to smoothen turbine operation / lessen fatigue (mass oscillation) which helps to optimize the reversible pump turbine characteristics. TÜV certification of SIL (Safety Integrity Level).

Axial Check Valves

Also named non-slam check valve: the spring-assisted design ensures ultra-fast closing with virtually no backflow and pressure surges (water hammer) in multi-pump systems. The full opening flow passage and the Venturi-shaped body result in ultra-low head losses which yield significant long-term savings due to reduced operating cost of pumps.
