全啟式帶手柄安全閥

Full open safety valve with handle

1、工業(yè)用安全閥、工藝成熟、做工細(xì)致、性能穩(wěn)定

1. Industrial safety valve, mature technology, meticulous workmanship, stable performance

2、彈簧全啟式；閥芯開(kāi)啟高度≥do/4（do為喉徑）

2. Spring full open type; valve core opening height ≥ do / 4 (do is throat diameter)

3、無(wú)手柄、全封閉式結(jié)構(gòu)

3. No handle, fully enclosed structure

4、有調(diào)節(jié)圈，可調(diào)節(jié)回座壓力、排放壓力

4. With adjusting ring, it can adjust the return pressure and discharge pressure

5、整定壓力P偏差：

5. Set pressure P deviation:

P≤5bar;偏差±0.15bar

P ≤ 5bar; deviation ± 0.15bar

5＜P≤23bar;偏差±3%P

5 ＜ P ≤ 23bar; deviation ± 3% p

23＜P≤70bar;偏差±0.7bar

23 ＜ P ≤ 70bar; deviation ± 0.7bar

P＞70bar;偏差±1%P

P > 70bar; deviation ± 1% p

6、回座壓力：85～90%整定壓力

6. Return pressure: 85-90% of set pressure
