Detailed Description

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. 3. Applicable gas: Series YQ: H2、O2、N2、CH4、CO、CO2、He、Ne、Ar and other non-corrosive gas. Series YQF: NH3、SO2、H2S、HCL、NO and other corrosive gas.
