Butterfly valves up to 12" are rated for 150 PSI service. 

Unlike other non-metallic butterfly valves, these are constructed from a one piece body with fully supported flanged bolt holes to prevent stressing of the mating pipe flanges.  The solid mounting pad ensures that an actuator will operate flawlessly, whether it is a manual lever, gear handwheel or automatic actuator.  The blowout proof stainless steel stem (titanium optional) in conjunction with a full body liner that has a V Notch retention configuration ensures a solid seat of the liner to the valve body.  An Integrally molded face seal facilitates positive sealing against mating flanges without the need for additional gaskets.  With only one o-ring on the disc to seal the valve and the full body liner, these valves are designed to ensure that the media never contacts the valve body.  These valves are specifically designed to retrofit into metal pipelines, however with no metal parts in contact with the fluid, they cannot corrode or rust, nor will they contaminate the fluid passing through them.  Please review our specification sheets above and use the CV calculate on them to determine the pressure drop for your system.  If you have any questions or require additional information, please contact us via email, phone or fax.
