Supply and delivery of one DN250 PN16 hydraulic altitude level control valve for Fountains Reservoir, Jeffreys Bay.

The valve must be a Cla-Val or approved equivalent, hydraulically operated, diaphragm-actuated, with CDS7 altitude pilot, pressure relief override, adjustable speed control, and mechanical valve position indicator. It must operate entirely hydraulically with no external electrical power.

Main valve: globe-pattern, ductile iron body and cover with fusion-bonded epoxy coating suitable for potable water.
