Type 3003 Electric rotary actuator

Type 2651 can be combined with…

同时也可关闭任一通道而使另外两个通道相连。

密封xn好；由于硬密封球阀的密封是采用人工研磨，

Technical data Valve size ¼" 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 

开关轻；由于硬密封球阀的密封圈底部采用弹簧使密封圈与阀芯紧紧抱在一起，

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；由于硬密封球阀的阀芯是合金钢喷焊，

所以在外界力量过弹簧的预紧力时开关非常轻。

• ¼"-1" 2000 PSI WOG, 1-¼"-2" 1500 PSI WOG • Thread ends

 • Standard port to Sch 40 pipe • Compact body size

 • PTFE seals, 4 seats design 

• Blow-out proof stem with self adjust packing

特别适用于含纤维、微小固体颗料等的介质。

而多通球阀在管道上不仅可灵活控制介质的合流、分流、及流向的切换，

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

本类阀门在管道中一般应当水平安装。

球阀按照驱动方式分为：气动球阀，电动球阀，手动球阀。

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

密封圈是合金钢堆焊，所以硬密封球阀在开关时不会产生太大的磨损。（它的硬度系数为65-70）：

As required Flow direction Seals to rated pressure in all directions Control option Size to conditions Pressure rating 2000 PSI ¼" - 1", 

1500 PSI 1 - ¼" - 2" Flow pattern “L” port  L + T port

球阀(ball valve ），标准GB/T21465-2008《阀门术语》中定义为：

直到阀芯与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

启闭件（球体）由阀杆带动，并绕球阀轴线作旋转运动的阀门。

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

耐磨；由于硬密封球阀的阀芯是合金钢喷焊，

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；由于硬密封球阀的阀芯是合金钢喷焊，

or blending control and diverting process applications.

Type 2051 Pneumatic rotary actuator

亦可用于流体的调节与控制，其中硬密封V型球阀其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.

与堆焊硬质合金的金属阀座之间具有很强的剪切力，
