进口蒸汽阀门|蒸汽开关阀|高温蒸汽阀门
进口蒸汽阀门(Steam Valve)是指用在蒸汽系统管道上的用来开关蒸汽，或者调节蒸汽流量，温度，压力，以及排出蒸汽中的冷凝水的各种阀门。威盾蒸汽阀门品质优良，广泛用在蒸汽系统管道上，起到提高蒸汽性能或者节能的效果，并使整个蒸汽系统高效运转。
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.
进口蒸汽阀门主要包括进口蒸汽闸阀，进口蒸汽截止阀，进口蒸汽柱塞阀，进口蒸汽止回阀，进口蒸汽疏水阀，进口蒸汽电磁阀，进口蒸汽安全阀，进口蒸汽减压阀等。
蒸汽阀门与其他的介质相比，具有它的特点：温度较高，有水又有气，一般的蒸汽管道经常冷热变化。所以蒸汽阀门的密封采用较高温的材料，阀体一般采用铸钢或者不锈钢，超高温的一般采用铬钼钢，或者铬钼钒钢。
