1. Service:
Series YQ, Series YQF bipolar pressure regulators mainly applies for précis control and adjustment for input pressure in line of analysis instruments, environmental protection equipment, power station, and non-corrosive(Series YQ) or corrosive (Series YQF) pure gas and standard mixed gas ,which would be sent into instruments after having been adjusted accurately.
2. Main technical data:
1. Type and Data TYPE/DATA YQ-1 YQ-2 YQ-3 YQ-4 YQ-5
YQF-1 YQF-2 YQF-3 YQF-4 YQF-5
Input pressure gauge range(MPa) 0～25 0 ～25 0～25 0～25 0～25
Output pressure gauge range(MPa) 0～0.6 0～0.16 0～4 0～0.25 0～1
Gauge class 2.5 2.5 2.5 2.5 2.5
Input pressure (MPa) ≤18.5 ≤18.5 ≤18.5 ≤18.5 ≤18.5
Output pressure (MPa) ≤0.45 ≤0.12 ≤3 ≤0.2 ≤0.75
Rated flow(m3/h) 0.6 0.06 1 0.2 0.6
2. Stability: Within the range of 5～15 MPa for air supply, outlet pressure variation less than 7×10-4MPa once inlet pressure changes 1Mpa.
3. 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.
4. Connection:
a. Inlet: G5/8¨(levorotation, dextrorotation), W21.85 14teeth/inch (levorotation, dextrorotation)
b. Outlet: M10×1; M8×1 hosepipe joint, etc.
