美國阿姆斯壯蒸汽疏水閥

SH-4000雙金屬型過熱蒸汽疏水閥

雙金屬型蒸汽疏水閥能夠處理大的啟動負荷。當系統溫度和壓力增大時，疏水閥的疊層式鎳－鉻雙金屬元件開始延展，當蒸汽到達疏水閥時緊閉閥門從而防止了蒸汽損失。 

雙金屬型疏水閥能抵抗水擊作用。依靠鈦質閥瓣和閥座，雙金屬型疏水閥確保在過熱蒸汽系統惡劣環境仍保持超長使用壽命。

SH-4000 Bimetallic Steam Traps

All Stainless Steel

For Pressures to 1,245 psig (86 bar)
Cold Water Capacities to 6,000 lb/hr (2,722 kg/hr)

Armstrong’s SH-4000 Bimetallic Steam Trap is the ideal design for applications involving superheated steam.

During start-up, the bimetallic mechanism is fully open and allows large volumes of non-condensable gases and condensate to be removed from the system. As the system reaches saturated steam conditions, the mechanism begins to close preventing anylive steam loss. The superheat during normal operating steam conditions keep the valve closed to ensure long service life.

In the event that operating conditions change and condensate forms at the steam trap inlet, the cooling effect allows the bimetallic mechanism to open and discharge any accumulation. The valve quickly closes once normal operating conditions return.

The SH-4000 consists of an investment cast, stainless steel body that is compact and highly resistant to harsh, corrosive environments. The integral mounting flange is compatible with the Armstrong IS-4, 4-bolt, Class 900, connector making for labor savings and easy steam trap replacement.
