進(jìn)口蒸汽閥門是指用在蒸汽系統(tǒng)管道上的用來開關(guān)蒸汽，或者調(diào)節(jié)蒸汽流量，溫度，壓力，以及排出蒸汽中的冷凝水的各種閥門。威盾蒸汽閥門品質(zhì)優(yōu)良，廣泛用在蒸汽系統(tǒng)管道上，起到提高蒸汽性能或者節(jié)能的效果，并使整個(gè)蒸汽系統(tǒng)高效運(yùn)轉(zhuǎn)。（Steam Valve）

The steam valve is used in the pipe of the steam system is used to switch the steam, or to adjust the steam flow rate, temperature, pressure, as well as the various valves of the exhaust steam condensate. Granville Shield steam valve quality, widely used in the steam system piping, played to improve steam performance or energy-saving effect and make the entire steam system operates with high efficiency.

進(jìn)口蒸汽閥門主要包括進(jìn)口蒸汽閘閥，進(jìn)口蒸汽截止閥，進(jìn)口蒸汽柱塞閥，進(jìn)口蒸汽止回閥，進(jìn)口蒸汽疏水閥，進(jìn)口蒸汽電磁閥，進(jìn)口蒸汽安全閥，進(jìn)口蒸汽減壓閥等。

蒸汽閥門與其他的介質(zhì)相比，具有它的特點(diǎn)：溫度較高，有水又有氣，一般的蒸汽管道經(jīng)常冷熱變化。所以蒸汽閥門的密封采用較高溫的材料，閥體一般采用鑄鋼或者不銹鋼，超高溫的一般采用鉻鉬鋼，或者鉻鉬釩鋼。
