BURKERT先導控制角座閥，187470
兩位兩通角座閥
適用于介質溫度+180℃
• 流量大
• 壽命長
• 螺紋連接和焊接口閥體符合ISO和DIN標準
• 標準供貨有閥座下或閥座上流向
• 可方便地更改回路功能
2000型外部先導控制角座閥由單作用或雙作用活塞執行機構驅動。執行機構有兩種材質，適用于不同的環境溫度。炮銅或不銹鋼兩通閥體，流量大。
可靠的自調整填料密封提供了高密封性。該免維護耐用閥可添加各種附件，從而具有位置指示、行程限位或手動開關等功能。

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.
