Certificate
All product registered by LR’s in accordance with CE/PED.
API 594 and API 6D certificate issued by American Petroleum Institute.
Inherently fire safe design
All VERVO check valves are inherently fire safe due to the valve design, material and construction. In case of fire, both resilient seat and metal seat valves provide metal to metal sealing performance.
Light weight and reduced size
Installation costs are greatly reduced by VERVO’s light weight and minimal space requirements. The compact design minimizes the distance between flanges and is easily installed between all flanges.
Horizontal/Vertical installation
Unlike most traditional swing check valves, VERVO check valves are ideal for both horizontal and vertical pipeline installation.
