Chief Features
The structure design of elastic sealing ring has been adopted for floating ball valves. This seat design features is a bigger sealing pressure ratio between the ring surface and the ball when medium pressure gets lower where the contacting area is smaller, thus the reliable seal is ensured.when the medium pressure gets higher, the contacting area between seat ring and ball becomes bigger as the sealing ring transforms elastically to under take the bigger force pushed by the medium without any damage.
A variety of soft seal and hard seal seat materials to meet more process conditions
The optimized limiting device further improves the accuracy of the valve passage and the flow CV control
ISO platform can be selected to facilitate the operation of the actuator
The valve meets NACE standard, fugitive emission function and fire test certification of API Spec 607
The valve seat is designed with two-way seal and low operating torque. All valves have built-in cavity relief devices to relieve pressure from the upstream seat and apply positive preload to ensure low pressure seal
