Product characteristics
According to the latest version of the APl609 standard requirements, combined with advanced design concepts and intelligent manufacturing technology, the use of replaceable elastic seat, with the following characteristics:
*Double eccentric structure designed to achieve the effect of opening and separating, closing and sealing.
*Uniquely designed lip seal structure with zero leakage at two-way bubble level for elastic interference and self-sealing.
*Interchangeable polymer and rubber seats are suitable for use under various operating conditions for optimal service life and effectiveness.
* All valves are standard with blow-out stem design to ensure safety and reliability in operating conditions.
* The packing is designed so that the product can be used under low leakage and vacuum conditions without adjustment and special treatment.
* The tangential pin of the valve stem is half on the valve plate and half inside the valve stem. The tangential positioning makes the valve plate and valve under extrusion pressure rather than shear stress, making the connection more reliable.
* Stem journal ends and valve plates in the valve body are designed to provide maximum stem support to enhance stem force and reduce switching torque and bearing wear. Valve plate closing limit block and valve body cast into one, so that the valve plate relative to the seat positioning accuracy, extend the service life of the seat.
*IS0 5211 standard upper flange and square connecting shaft for integral casting for easy and reliable connection to any form of drive
