2 Swg Check Valve, Cast Steel, Bolte Bonnet esign VahnTech cast steel check valves are esigne to provie maximum service life an urability. All check valves are manufacture to the American Petroleum Institute Stanars API 00 & API, British Stanars BS EN 0 an also conform to the American Society of Mechanical Engeer s Stanar ASME B.. Materials Stanar boy/bonnet materials clue ne graes of carbon, low alloy an staless steel. For special applications, they can be supplie other graes of alloy an staless steel. Trim, packg an gasket materials can be selecte from a wie range to match service conitions.

This esign can be use to either ampen or assist closg of the check valve isc epeng on orientation. By usg the hyraulic control unit to buffer action from the isc, the valve opens at lower flow rates.
