First Control Valve to Achieve API 641 Certification

Clarke Valve announces the API 641 certification of its proprietary Dilating Disk™ Valve design, the first control valve to achieve this certification of low fugitive-emission performance.

This API test standard calls for 610 cycles of the valve under extreme temperature fluctuations to evaluate emissions performance over an accelerated life cycle.
