This flapper-type valve design has remained virtually unchanged and unchallenged over the years due to its simplicity of operation and field-servicing ease.
Below the valve body a special threaded sub offers long wear and easy replacement should lower threads become damaged, and, when removed allows easy access to the valve cavity for repair. The valve must be manually closed. It can be partially opened by starting up the mud pumps, but must be fully opened manually to prevent mud cutting.
