Certificate

Inherently fire safe design

All COTECH 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 COTECH’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, COTECH check valves are ideal for both horizontal and vertical pipeline installation.
