產品概述 Product Overview

HPR439型調壓閥是一種彈簧設定直接作用微壓調節閥，可將較高壓力的氣體一次

節流減壓穩壓極低壓力，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。控制壓力O.3KPa，控制壓力為15KPa，使用溫度-48℃，

使用溫度120 ℃。

可用于儲罐，除塵器，料倉充入惰性氣體氮封，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℃
