聯(lián)系我時,請告知來自 儀表網(wǎng)FRI/6 平衡型,帶可調(diào)設(shè)定點彈簧的彈簧加載壓力調(diào)節(jié)器。用于調(diào)節(jié)輸出壓力的內(nèi)部傳感器。集成 50 微米氣體過濾器??芍苯影惭b A2 壓力開關(guān)。
冬斯-壓力調(diào)節(jié)器
FRI/6 平衡型壓力調(diào)節(jié)器將壓力調(diào)節(jié)器和 50 微米氣體過濾器組合在一個外殼中。使用 FRI/6 與大多數(shù) DMV 截止閥可以進行各種組合,以形成緊湊的模塊化系統(tǒng):
- 帶螺紋法蘭的單獨式壓力調(diào)節(jié)器和氣體過濾器,或直接安裝到 DMV 尺寸 701、702 和 703 系列安全截止閥上。
- 通過直接安裝 A2 型壓力開關(guān)監(jiān)控調(diào)節(jié)器輸出壓力。檢測入口和出口壓力的附加端口也位于螺紋法蘭上。
- 重型隔膜結(jié)構(gòu),具有耐用性和強度。
- 出口壓力的穩(wěn)定、精確和瞬時調(diào)節(jié)。
- 鎖定式調(diào)節(jié)器(詳見第 2 頁和第 3 頁)。
- 工廠安裝的排氣限制器。查看排氣管要求的適用規(guī)范。
應(yīng)用 FRI/6 壓力調(diào)節(jié)器推薦用于工業(yè)和商業(yè)加熱應(yīng)用,適用于天然氣、丙烷、丁烷、空氣和惰性氣體。適用于按體積計高達 0.1 % 的干燥 H2 S。
“干燥"氣體的露低點低于 +15 °F,其相對濕度低于 60 %。

Body sizes Flanges | FRI 705/6 - FRI 707/6 | FRI 710/6 - 712/6 |
1/2" - 1" NPT or Rp | 1" - 2" NPT or Rp | |
Max. operating pressure | 7 PSI (500 mbar) UL and CE | |
5 PSI (350 mbar) CSA | ||
Max. body pressure | 15 PSI (1000 mbar) | |
Input pressure range | 2 in. W.C. to 200 in. W.C. (5 mbar to 500 mbar) | |
Output pressure range | 1 in. W.C. to 60 in. W.C. (2.5 mbar to 150 mbar); adjustable with different springs Actual outlet pressure is +/- 15 % of set pressure (15 % hystersis/droop) | |
Materials in contact with gas | Housing: | Aluminium |
Seals and diaphragms: | NBR-based rubber | |
Ambient temperature rating | +5 °F to +150 °F for up to 7 PSI for regulating behavior (+/- 10 % of setpoint). | |
-40 °F to +150 °F: Diaphragms are suitable for the low temperature, but there may be out of range regulating behavior. | ||
CSA Certified for -40 °F to +150 °F for up to 5 PSI. | ||
-15 °C to +70 °C applies to the CE Marking. | ||
Installation position | Regulator dome from vertically upright to lying horizontally | |
Test ports/ Pressure switch mounting ports | One G 1/8 ISO 228 test ports on each side of regulator, sensing downstream pressure, and one on each inlet and outlet flange (if used as a stand alone regulator). | |
Gas filter (standard) | 50 micron; replaceable | |
Vent line / Back loading port/ Breathing plug | Vent line connection is G 1/4 ISO 228. The FRI also has a factory installed vent limiter, which limits the escape of gas to less than 0.5 CFH @ 5 PSI in case atmospheric diaphragm ruptures. Venting required unless otherwise accepted by the authority having jurisdiction. | |
Hysteresis/Droop | Hysteresis is less than 10 % for up to 7 PSI inlet. | |
Average droop at 20:1 turndown is 10 % for up to 7 PSI. |
