Type 3003 Electric rotary actuator

Type 2651 can be combined with…

同時也可關閉任一通道而使另外兩個通道相連。

密封xn好；由于硬密封球閥的密封是采用人工研磨，

Technical data Valve size ?" to 2" Body materials1) Ball material Stem material CF8M (cast 316 SS) 316 SS 316 SS Port diameter class 

Standard port to Sch 40 pipe size Ball seal material PTFE (others to application) Media Compatible with materials of construction 

and  pressure / temperature limits of seals Viscosity As torque effect allows Packing gland Self-adjusting PTFE and FKM 

開關輕；由于硬密封球閥的密封圈底部采用彈簧使密封圈與閥芯緊緊抱在一起，

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. 

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. 

耐磨；由于硬密封球閥的閥芯是合金鋼噴焊，

所以在外界力量過彈簧的預緊力時開關非常輕。

 ? Standard port to Sch 40 pipe ? Compact body size

 ? PTFE seals, 4 seats design 

? Blow-out proof stem with self adjust packing

特別適用于含纖維、微小固體顆料等的介質。

而多通球閥在管道上不僅可靈活控制介質的合流、分流、及流向的切換，

with  304SS guide / follower Media temperature -20°F to 375°F (PTFE) End connections NPT – National pipe thread tapered Installation 

本類閥門在管道中一般應當水平安裝。

球閥按照驅動方式分為：氣動球閥，電動球閥，手動球閥。

Ball Valves in cast 316 SS  3-way, screwed body

密封圈是合金鋼堆焊，所以硬密封球閥在開關時不會產生太大的磨損。（它的硬度系數為65-70）：

球閥(ball valve ），標準GB/T21465-2008《閥門術語》中定義為：

直到閥芯與密封圈完全吻合才能使用。所以他的密封性能是的。

 ? ISO 5211 direct actuator mount

Type 3004 Electric explosion proof actuator

Type 3005 Electric rotary actuator

啟閉件（球體）由閥桿帶動，并繞球閥軸線作旋轉運動的閥門。

The Type 2651 is automation ready with an ISO 5211 mounting pad for direct coupling of the actuator. 

耐磨；由于硬密封球閥的閥芯是合金鋼噴焊，

or blending control and diverting process applications.

Type 2051 Pneumatic rotary actuatorThe Type 2651 is automation ready with an ISO 5211 mounting pad for direct coupling of the actuator. 

耐磨；由于硬密封球閥的閥芯是合金鋼噴焊，

or blending control and diverting process applications.

Type 2051 Pneumatic rotary actuator

亦可用于流體的調節與控制，其中硬密封V型球閥其V型球芯

bA full range of actuators, pilots, digital positioners, 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.

與堆焊硬質合金的金屬閥座之間具有很強的剪切力，
