Stability:
within the range of 5-15 Mpa for air supply,outlet pressure variation less than 7X10-4Mpa once inlet pressure changes 1Mpa.
Flow characteristic:When inlet pressure more than 2Mpa,control flow rate changes within rated range,output pressure changes not more than
±6% of upper limit of output pressure gauge measuring range.
Connection:

Ⅰ Features
1. Mental film in the valve replaces traditional rubber film, and all sealing
materials are made from PTFE to ensure that highly purified gases will
not be secondarily polluted.
2. Simple and wise structure with multiple filtering sets, rigid and durable,
and suitable for replacement and operation of various kinds of gases.
3. High pressure-resistant structure, distinguished sealing performance.
4. Remarkably improved pressure characteristics and flux characteristics
compared with ordinary pressure reducing valve.
5. Complete models and standards of products; input and output connections
comply with the requirements of users, which can meet the requirement of
various uses.
6. The inner and outer materials of YQJF are all made of corrosion resistant
stainless steel with excellent performance of corrosion resistance.
7. The regulator can also be installed on a panel or a fixed bracket, in
addition to serving as a pressure reducing device for steel bottles
containing high-pure gas.
8.Many varieties and high performance-price ratio
