The M&J Valve portfolio from Celeros Circulation Expertise contains the DANFLO axial surge reduction movement management valve, which is designed to guard pipelines, pumps and different gadgets from transient surge overpressures. Functions embrace oil, fuel or liquid pipelines, tanker terminals, metering techniques, injection and restoration techniques, pump station bypass and underground storage installations.
Surge stress is outlined because the fast change in pipeline stress brought on by a change of movement fee within the liquid pipeline. Surge occasions may be triggered just by closing a valve too shortly. The ensuing stress surge travels at sonic velocities by the pipeline, reaching speeds of as much as 1000 m/sec. It could trigger extreme infrastructure injury, lack of product and environmental hurt, in addition to posing a major danger to personnel security.
DANFLO surge reduction valves (SRV) supply a really fast response time and excessive movement capability, making them ideally suited to surge management purposes. These valves are engineered to trace unabated surge-wave stress transient – opening shortly, then closing with out slamming shut. The valve options an axial ‘straight-path’ clean movement sample and has a big annular movement space for top stress restoration, low stress drop and excessive movement coefficients. It achieves surge management by loading the plug cavity from a regulated nitrogen supply. A line stress surge above the nitrogen set stress opens the valve instantly. Transient surge stress is thus decreased as the additional surge quantity is relieved. The plug then tracks line stress till equilibrium is re-established and the valve closes. The nitrogen-operated DANFLO SRV is ideally suited to soiled service, corresponding to crude oil and sea water pipelines. A pilot-operated various can be out there for clear service purposes.
Designed and manufactured by M&J Valve in Texas, USA, the DANFLO SRV is accessible in line sizes 2 – 16 in., class 150 – 900, with varied low noise and cavitation trim choices. A compact management module, comprising a management panel, bottle rack and plenum, can be out there. DANFLO SRVs and management modules may be specified as particular person items, or equipped as full single or multi-run skid techniques. Moreover, for the final word in surge reduction safety, M&J Valve gives its patented rate-of-rise system. This combines the DANFLO SRV with a predictive stress rate-of-rise system to permit pre-emptive motion towards a creating surge occasion, supporting situation monitoring and preventive upkeep regimes.
Clients for these high-quality OEM surge movement valves and techniques also can profit from the full lifecycle help that M&J Valve gives. Choices embrace modular and extremely customisable skid building, engineering design companies, set up and commissioning, and upkeep companies.
