HPR439型調(diào)壓閥是一種彈簧設(shè)定直接作用微壓調(diào)節(jié)閥，可將較高壓力的氣體一次

節(jié)流減壓穩(wěn)壓極低壓力，用于閥后控制。適用于各類氣體的微壓控制，特別適用于

微壓氮封?？刂茐毫?/span>O.3KPa，控制壓力為15KPa，使用溫度-48℃，

使用溫度120 ℃。

可用于儲(chǔ)罐，除塵器，料倉(cāng)充入惰性氣體氮封，降低氧含量，防止氣體和粉塵爆炸

HPR439 Pressure regulating valve is a spring-driven micro-pressure regulating valve and

can reduce and stabilize high-pressure gas to the extreme low pressure. It is only used for

downstream pressure control. It is also used for micro-pressure control of different gases.

Especially apply to the nitrogen blanketing system. The minimum control pressure is 0.3KPa. The

maximum control pressure is 15KPa. The minimum operation temperature is-48℃The maximum

operation temperature is 1200℃
