Product characteristics
According to the latest version ofthe APl609 standard requirements,combined with advanced design concepts and intelligent manufacturingtechnology,the use ofreplaceable elastic seat, with the followingcharacteristics:
*Double eccentric structure designed to achieve the effect of openingand separating, closing and sealing.
*Uniquely designed lip seal structure with zero leakage at two-waybubble level for elasticinterference and self-sealing.
*Interchangeable polymer and rubber seats are suitable for use undervarious operating conditions for optimal service life and effectiveness.
* All valves are standard with blow-out stem design to ensure safety andreliabilityin operating conditions.
* The packing is designed so that the product can be used underlowleakage and vacuum conditions without adjustment and specia treatment.
* The tangential pin of the valve stem is half on the valve plate and halfinside the valve stem.The tangential positioning makes the valve plateand valve under extrusion pressure rather than shear stress, making theconnection more reliable.
* Stem journal ends and valve plates in the valve body are designed toprovide maximum stem support to enhance stem force and reduceswitching torque and bearing wear.Valve plate closing limit block and valve body cast into one, so that thevalve plate relative to the seat positioning accuracy, extend the serviceife of the seat.
*IS0 5211 standard upper flange and square connecting shaft forintegral casting for easy and reliable connection to any form of drive
