Description
Nozzle Check valves are designed and manufactured according to the following International codes and process requirement.
DESIGN AND MANUFACTURING:
ASME B 16.34: Valves-Flanged, Threaded, and Welding End.
EN12516:Â Industrial valves. Shell design strength. Tabulation method for steel valve shells
INSPECTION AND TEST:
API 598:Â Valve Inspection and Testing.
EN12516:Â Industrial valves. Shell design strength. Tabulation method for steel valve shells
FLANGE DIMENSION:
EN 1092-1:Â Flanges and their joints. Circular flanges for pipes, valves, fittings and accessories, PN designated. Steel flanges.
ISO 7005-1:Â Steel flanges for industrial and general service piping systems.
BS 4504 Sect.3.2:Â Circular flanges for pipes, valves and fittings (PN designated). Steel, cast iron and copper alloy flanges. Specification for cast iron flanges.
ASME B16.1:Â Cast Iron Pipe Flanges and Flanged Fittings.
ASME B16.5:Â Pipe Flanges and Flanged Fittings
- Protect drinking water from contamination by backflow resulting from gravity, back siphonage or backpressure (e.g. Hose connected kitchen spray or shower hand spray).
- Protect sensitive equipment against possible damage or contamination resulting from a reversal of flow direction (e.g. water meter, pump or filter).
- Hold water in a system or pipe after the flow has been turned off to prevent drainage or facilitate restart (e.g. pumping systems).
- Prevent crossover flow in systems with unequal line pressures (e.g. cold and hot water inlets in thermostatic mixers).
- Reduce the risk of backflow or leakage in case of valve failure (e.g. solenoid valve at the inlet of an appliance).
- Allow complex systems to function properly by ensuring unidirectional flow (e.g. multi-zone heating system or booster pumps).
