Double Eccentric Butterfly Valve is an innovative double offset design product with advanced world leading technology. This butterfly valve has a unique structure with ultra reliable sealing performance, wide working conditions and low operation torque.
Series - 150 | PN6-PN25
Design Features
- Rocker-shaped gland bridge compensates for uneven adjustment of gland nuts reducing packing leaks
- Integrally cast disc position stop perfectly locates the disc in seat, achieving maximum seat and seal life
- Extended neck allows for 50 mm (2″) of pipeline insulation
- Integrally cast mounting pad provides direct mounting of actuators eliminating the need for costly brackets and couplings
- Flattened body bore at shaft journal ports positions shaft bearings near disc, providing maximum shaft support resulting in reduced wear and longer life
