Reval 182
Reval 182是用于中低壓的先導(dǎo)控制壓力調(diào)節(jié)器。
Reval 182是一個(gè)“失敗關(guān)閉”調(diào)節(jié)器，即如果：
?主隔膜失效
?導(dǎo)向膜片失效
?沒有饋送到導(dǎo)頻環(huán)路。
這些調(diào)節(jié)器適合與預(yù)過濾的非腐蝕性氣體一起使用。

PILOT-OPERATED GAS PRESSURE REGULATORS

Reval 182

The Reval 182 is a pilot-controlled pressure regulator for medium and low pressure.
The Reval 182 is a 'fail close' regulator, i.e. it closes if:
•    The  main diaphragm fails
•    The  pilot diaphragm/s fail
•    There is no feed to the pilot loop.
These regulators are suitable for use with pre-filtered, non-corrosive gases.FeaturesTechnical data
