Series PVQ Model Selection ∆P = (P1 – P2) MPa ∆P: Pressure differential P1 : Inlet pressure P2 : Outlet pressure Condition 1. P1 = 0.7 MPa, P2 = 0 MPa (Atmospheric pressure) Refer to curve A when ∆P is 0.7 MPa. Ex) At increasing currents, when a 140 mA current is applied, a flow rate of 85 l/min is achieved. (See q.) If current decreases at this point, the flow rate may not change by 135 mA due to hysteresis. (See w.
Model Selection Q. Required flow rate = 0 to 75 l/min. P1 = No conditions, P2 = 0 MPa (Atmospheric pressure) In this case, all of PVQ30 series orifice sizes satisfy the required flow rate. (Flow rate when rated current is applied) The table below shows the pressure differentials needed to satisfy the required flow rate. In the flow rate characteristic charts, a pressure differential over the flow rate indicated by the dashed line (75 l/min.) up to the max.

Glossary Proportional control The fluid is controlled proportionally according to an input signal (current). Max. operating pressure differential Indicates the max. pressure differential (difference between the inlet and the outlet pressure) which is allowed for operation with the valve closed or open. Max. operating pressure Indicates the limit pressure that can be applied to the inlet.
Series PVQ Safety Instructions These safety instructions are intended to prevent a hazardous situation and/or equipment damage. These instructions indicate the level of potential hazard by labels of "Caution", "Warning" or "Danger". To ensure safety, be sure to observe ISO 4414 Note 1), JIS B 8370 Note 2) and other safety practices.
2/3 Port Process Valves Precautions 1 Be sure to read this before handling. For detailed precautions on every series, refer to main text. Design Warning 1. Cannot be used as an emergency shutoff valve, etc. The valves presented in this catalog are not designed for safety applications such as an emergency shutoff valve. If the valves are used in this type of system, other reliable safety assurance measures should also be adopted. 2.
2/3 Port Process Valves Precautions 2 Be sure to read this before handling. For detailed precautions on every series, refer to main text. Piping Mounting Caution Warning 1. If air leakage increases or the equipment does not operate properly, stop operation. 4. Always tighten threads with the proper tightening torque. After mounting is completed, confirm that it has been done correctly by performing a suitable function test.
2/3 Port Process Valves Precautions 3 Be sure to read this before handling. For detailed precautions on every series, refer to main text. Operating Environment Maintenance Warning Warning 1. Do not use the valves in an atmospheres having corrosive gases, chemicals, salt water, water, steam, or where there is direct contact with any of these. 2. Do not use in explosive atmospheres. 3. Do not use in locations subject to vibration or impact. 4.
Series PVQ Specific Product Precautions Be sure to read this before handling. Power Source Selection Caution Operation in Vacuum Caution This product makes proportional control possible with constant current. When the product is used in vacuum, apply vacuum pressure to A (2) port. If controlled with voltage, the output flow rate cannot be kept constant due to current fluctuation. Use a stable DC power source with sufficient capacity without much ripple.
