*1. The notations mL/min (standard) and L/min (standard) indicate the volume flow rate per minute converted to 20 ˚C,
one atmosphere (101.3 kPa (abs)). The reference temperature can also be changed to 0 ˚C, 25 ˚C or 35 ˚C.
*2. Air/nitrogen is the factory setting. By changing the setting, this model can be used for argon, carbon dioxide (CO
2
),
city gas 13A (LNG: 46 MJ/m
3
), city gas 13A (LNG: 45 MJ/m
3
), propane 100 %, methane 100 %, or butane 100 %.
Additionally, semi-standard gas models that can be used for ammonia or acetylene (seal material: EPDM) can also be
manufactured. (MQV0200/0500 only)
*3. Oxygen is the factory setting. By changing the setting, this model can be used for air/nitrogen, argon, carbon dioxide
(CO
2
), city gas 13A (LNG: 45 MJ/m
3
), propane 100 %, methane 100 %, or butane 100 %. However, once this device has
been used for a gas other than oxygen, never reuse it for oxygen.
*4. The flow rate ranges in the above table are for use of this device for air. The controllable flow range may vary
depending on the type of gas.
 Gas type and control range (P. 7-11).
*5. When oxygen is selected as the gas type, selection “1,” “gas-contacting parts treated to be oil free,” must be selected
for Optional function 4.
*6. The MQV0050(J, K) is for low differential pressure and is controllable to a high flow rate range with lower differential
pressure than the MQV0050(B, C).
