Pressure Control Valve allows air to move at up to 150 psig.
April 28, 2009 -
Suited for use with flow meters, QL3 Pressure Control Valve utilizes current driven variable orifice proportional solenoid valves combined with analog PID circuit on high flow volume booster to optimize air movement. PID circuit integrates error out to maximize resolution, and volume booster is designed so there are no stamped gaskets or molded diaphragms or seal parts; all of parts related to normal maintenance are standard o-rings.
Proportion-Air QL3: High Resolution Control at High and Low Flow
McCordsville, IN - Today Dan Cook the founder and president of Proportion-Air, Inc. announced the latest addition to the product line, the new QL3 Pressure Control Valve. The QL3 allows high volumes of air to move quickly and precisely at pressures up to 150 psig using proportional solenoid valves with a unique analog PID circuit. Ideal for use with flow meters, it provides high resolution and smooth pressure control at high and low flow rates and avoids the "steps" prevalent in most feed and bleed I/P's. The output pressure is proportional to the electrical input or command signal.
The QL3 improves and builds on the proven Proportion-Air QB3 series' high performance using a current driven variable orifice solenoid valve and the analog PID circuit. The PID circuit integrates error out quickly resulting in superior resolution. This combination of the "stepless" solenoid valve with a high speed analog PID on a high flow volume booster is what allows large volumes of air to be moved with precision at a very high flow rate.
The QL3 is also easily serviced. The volume booster is designed so there are no stamped gaskets or special molded diaphragms or seal parts. All of the parts related to normal maintenance are standard o-rings. Complete repair kits are available, but in case emergency repair is needed parts should be available from any fluid power distributor or even most neighborhood hardware stores.
