THE INSIDE STORY OF THE QPV OR MPV: QPV2 or MPV2 Accepts Feedback Signal from an External Sensor Access Hole Permits Field Adjustments QPV has an IP65 Enclosure Allows it to Endure the Elements and be Washed Down Without Harm Electronic Control Circuit Pressure Zero and Pressure Span Adjustments Available in a Wide Range of Electrical Control Inputs and Analog Outputs Adjustable Hysteresis Band & System Stability Many Connector Options Proportional Inlet Valve Mounts in any Position Exhaust Valve Multiple Mounting Brackets Available 1/8” NPT Supply Port QPV Weights 1.02 LBS (0.5 KG) MPV...

The QPV member of the ultra high resolution family is designed for applications where the environment requires that the internal components are protected. The anodized aluminum housing of the QPV offers NEMA 4 or IP65 rated protection for this fully enclosed version. Several different mounting configurations and mounting accessories are available. The MPV version has been designed for OEM applications where protection from the environment is not necessary. The MPV incorporates extremely versatile mounting capabilities that allows for DIN rail mounting, panel mounting or manifold mounting of...

QPV OR MPV PERFORMANCE CHARACTERISTICS RESPONSE TO STEP INPUT LINEARITY LINEARITY RESPONSE TO STEP INPUT Command [Volts] This chart shows the linear characteristics of QPV or MPV products when given a ramp signal from 0-10 volts. Characteristics would be similar for 420 mA units. Times for QPV or MPV (0.040” valve orifice) to fill/exhaust a closed chamber. Step command signal is superimposed over pressure trace. Time is determined by difference between command signal and pressure achieved. When flow or leakage is present in the system, traditional two valve I/P’s bleed down and then actuate...

QPV OR MPV TYPICAL APPLICATIONS LEAK TESTING (METHOD 1) Controller DS - Series Pressure Transducer Part Under Test Media Supply A Proportion-Air control valve can precisely control pressure to leak test parts. Once the test part is pressurized by the QPV1, the controller closes the shutoff valve. The DS-Series pressure transducer senses pressure in the part under test. Leak decay is recorded by the controller. Once the test is completed, the controller opens the shutoff valve and pressure is relieved through the QPV1. LEAK TESTING (METHOD 2) Controller Article under Test Flow Transducer...

In this application a QP E tro-pneumatic control valve is c ontrolling pressure of air over V1 lec flux, thus controlling the amount of flux whic h being dispensed. Why a QPV1? B ecause this is a low flow, low pressure applic ation that c an be maintained using the QP V1. HIGH RESOLUTION FORCE CONTROL USING AIR-PEL CYLINDERS Controller PLC, PID, Potentiometer, etc Manifold mount MPV1 Air Supply Air-Pel Cylinders Part Under Test In this application, 7- MPV1's mounted on a SBM-7 sub-base manifold are controlling the force on spring loaded Air-Pel cylinders to test the breaking point of small...
