Capacities to 11,000 lb/hr (4990 kg/hr)

SH-900 Series Superheat Steam Traps operate by the effect that rising temperature has on the thermostatic bimetallic elements.

At start-up, the valve is wide open, which allows a large volume of non-condensables and cold condensate to be removed from the system. When the system reaches steam temperature, the elements become sufficiently hot to pull on the trap’s valve stem, closing the valve.

The valve remains closed until the bimetallic elements cool, thus allowing the valve to crack open, vent the condensate and non-condensables, and then close again when steam temperature is reached.

The SH Series Superheat Steam Traps adjust automatically to changing conditions. Hot elements in the valve generate forces to offset rises in pressure.

雙金屬型過(guò)熱蒸汽疏水閥

雙金屬型蒸汽疏水閥能夠處理大的啟動(dòng)負(fù)荷。當(dāng)系統(tǒng)溫度和壓力增大時(shí)，疏水閥的疊層式鎳－鉻雙金屬元件開(kāi)始延展，當(dāng)蒸汽到達(dá)疏水閥時(shí)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(zhì)閥瓣和閥座，雙金屬型疏水閥確保在過(guò)熱蒸汽系統(tǒng)惡劣環(huán)境仍保持超長(zhǎng)使用壽命。
