The Hydrocore™ energy dissipator was designed and developed in collaboration with members of various universities in South Africa in the late 1990’s. These studies, which determined the tolerable perimeters of the valve, were done in accordance with several standards that are mentioned below.
Scope of Applications
The Hydrocore™ energy dissipator is a tailor-made device, used in open end applications and designed to reduce the upstream pressure ‘Pu’ (max up to 250 bar) to a set pressure ‘Pd’ (max up to 100 bar) at a designed flow rate
The design of the Hydrocore™ energy dissipator complies with various international standards. The most prominent ones are:
ASME Boilers & Pressure Vessels Design Code
250 bar (max) working pressure
Up to 85ºC with standard seals.
Liquid and gas with low content of suspended solids.
2” (50 NB) to 16” (400 NB)
SABS 1123, BS4504, BS10, ASME B16.34, ANSI B16.5
pH levels & chlorides
Parts of the valve are made from stainless steel and can withstand a low level of chlorides.
The valve can be installed in any position
12 NB Flow: 1-2 ℓ/sec
25 NB Flow: 3-6 ℓ/sec
38 NB Flow: 7-14 ℓ/sec
50 NB Flow: 12-24 ℓ/sec
80 NB Flow: 30-60 ℓ/sec
100 NB Flow: 47-94 ℓ/sec
150 NB Flow: 106-212 ℓ/sec
200 NB Flow: 188-376 ℓ/sec
250 NB Flow: 294-588 ℓ/sec
300 NB Flow: 424-848 ℓ/sec
350 NB Flow: 577-1154 ℓ/sec
400 NB Flow: 754-1508 ℓ/sec
The length of the energy dissipator is determined by the required pressure drop ‘Pu - Pd’, which determines the number of pressure reduction stages.
