由兩部分或三部分構成的球閥
氣動驅動裝置
緊湊型結構
? PTFE seals, 4 seats design
? Blow-out proof stem with self adjust packing
Ball Valves in cast 316 SS 3-way, screwed body
This Burkert ball valve design is an industry proven threaded investment cast body with PTFE/FKM sealing.
It finds wide use in mixing, blending and diverting applications at reduced torque.
驅動裝置具有一個用于顯示活塞位置的光學指示器。
此款緊湊型氣動球閥具有非常廣泛的用途，
? Standard port to Sch 40 pipe
? Compact body size
The self-adjusting packing gland is a dual sealing type with an alignment collar for superior tightness.
The Type 2651 is automation ready with an ISO 5211 mounting pad for direct coupling of the actuator.

Type 2651 can be combined with…
? ?"-1" 2000 PSI WOG, 1-?"-2" 1500 PSI WOG
feedback switches and bus network options are available for integration into plant control systems.
For maintenance, this design allows removal of all seals through three ports.
The screwed body provides for easy re-assembly, and more compact than multi piece bolted designs.
The ball is standard port style, presenting a CV
