BURKERT先导控制角座阀，187470
两位两通角座阀
适用于介质温度+180℃
• 流量大
• 寿命长
• 螺纹连接和焊接口阀体符合ISO和DIN标准
• 标准供货有阀座下或阀座上流向
• 可方便地更改回路功能
2000型外部先导控制角座阀由单作用或双作用活塞执行机构驱动。执行机构有两种材质，适用于不同的环境温度。炮铜或不锈钢两通阀体，流量大。
可靠的自调整填料密封提供了高密封性。该免维护耐用阀可添加各种附件，从而具有位置指示、行程限位或手动开关等功能。

Ultra–compact Y–pattern valve
3/8 – 3/4 NPT
• High cycle life
• Cost effective ball valve alternative
• High operating safety:
– Maintenance–free spring loaded packing
with intermediate relief and wiper
– Self aligning PTFE seal/plug
• Optical position indication standard
• Cost–savings in operation due to
minimized control air consumption
• Low Lifecycle costs
The pneumatically–operated 2/2–way Y–pattern
valve is operated by an ultra–compact piston
actuator. Despite the small dimensions of the actuator,
high pressure can be switched without problems.
The Y–pattern construction of the body makes
possible extremely high fl ow rates, particularly
in comparison to conventional globe valves. The
proven, self–adjusting and maintenance–free
Burkert packing glands ensure high sealing integrity.
