Blackhall's Hollow-Jet Free Discharge Cone Valve operating at Digley Reservoir, UK

Due to the high reservoir head and draw down velocity, existing scour valves at Digley Reservoir, Huddersfield became stiff and difficult in operation. Serious constraints ruled out the option of Gate & Butterfly valve as a solution.

The client came to Blackhall Engineering Limited for a special and long-lasting valve solution. Using our experience, expertise and leading technologies we designed and manufactured the Fixed Cone Free Discharge Valve also known as Hollow-Jet Valve which proved as an ultimate solution to the problem.

The performance of the valve was highly praised by client.
