Description
The ZZY series self-operated pressure regulator is a kind of gas, air, or water regulator that does not need outside power but takes advantage of the power from medium to act and adjust by itself. The most notable feature of this series regulator is that it can be used in the working place without the electricity and gas supply, which saves power at the same time. In the specific range, the pressure setting can be adjusted at will.
Based on the difference of any working condition, the ZZY series self-operated pressure regulator can be classified into 3 types according to its inside part: ZZYP (single-seat self-operated pressure regulator); ZZYM (cage type self-operated pressure regulator); ZZYN (double seat self-operated pressure regulator), customers can also choose the type by the local actual working condition(differential pressure, temperature, medium state) or leakage requirement. There are 3 different bonnet types according to the working condition: standard (normal condition), long neck type(big range for pressure adjusting), heat radiation type(temperature 350~550°C). The ZZY series
Self-operated pressure regulator applies with the quick opening flow characteristic, which is quickly acted and highly accurate adjusted (error≤10%), so it can be widely used in many fields like petroleum, chemical, electricity, metallurgy, food, textile, machinery, and civilian building and so on to reduce/release or stabilize the pressure of the gas, steam, and liquid and so on.
