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.

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

Installation and Regulation
1 Make sure no oil or grease before use.
2 Install the pressure regulator on a gas bottle properly, and screw inlet
connector tightly to ensure no gas leakage (examine with leak-test
agent or no-fattiness soap water when necessary). Do not touch any
fatty matters during the operating process.
3 Before opening the gas bottle, turn and loose the handle of pressure
regulator to make the spring be a fully-loose state (or state of bearing
no force), in order not to damage the low-pressure gauge. When
opening gas source, do not stand in front of or behind the pressure
regulator. Then slowly open gas source valve until high-pressure valve
completely indicates the pressure of gas bottle. Adjust output pressure.
Turn the handle in clockwise to increase output pressure, or turn the
handle anti-clockwise to decrease output pressure.
4 Slowly turn the handle to adjust to the user’s working pressure (or tap
meter head with your hand to avoid higher adjustment error). If actual
pressure is higher than working pressure, circumrotate and loose handle
to release some gas and then adjust again. (Or re-adjust to ensure
meeting the using requirements after pressure regulator have worked for
2 hours when necessary).
5 If expecting to stop pressure regulator, turn off gas source valve, then
circumrotate and loose handle to set the spring into a fully-loose state.
6 The working pressures of two of the meter heads should not higher than
75% of the measure upper limit, and receive checkout periodically and
replace meter head if unqualified.
7 Store and maintain pressure regulators properly before and after using,
avoiding impact and shake, adjustment handle must be set in loose state.
8 Pressure regulator must be stored in place containing no erosive
medium.
Ⅴ, Maintenance:
1 , We responsible the regulator for one year if it occurs quailty
problem(improper use is not included)
2, Please sent regulator back to manufacturer if it need repaired
! Note:
1, Two safe valves are adjustable and preseted by manufacturer
2, Don’t disassmeble any parts at random
