  • Proportional Valves
    . Proportional valve parts are built to be interchangeable; thus, the spool in low-performance valves can have considerable overlap in the null position. This overlap causes flow deadband, which is not critical for flow-control systems but can cause errors and instability in positioning systems. However
  • Proportional valves eliminate design headaches
    New design produces consistent flow and gain. The EPV proportional valve has standard and manifold mounting options, a variety of orifice sizes and control voltage ranges, and three different electrical connectors. Performance curves for two conventional proportional valves show wide variations
  • A Closer Look At Proportional Control
    A new proportional valve positions the solenoid's moving parts outside the core of the coil. This eliminates the need for tightly toleranced parts and prevents the armature from rubbing against the housing. The critical specifications engineers evaluate when selecting high-performance proportional
  • Proportional Valves Eliminate Design Headaches
    Proportional valves are a great alternative when an application requires more than on-off control, but not the high precision and expense of servo valves. As such, proportional valves are widely used in a multitude of applications, including the control of gas and air flow from medical respirators
  • Proportional Valve Could Improve Respirators
    Designers of ventilators, respirators, and blood pressure monitors could benefit from a new proportional pneumatic valve that reportedly offers greater air flow control accuracy. The new valve, introduced by Clippard Instrument Laboratory, Inc. (Cincinnati, OH; and known
  • Proportional Valve Design Meets Control System Challenges
    Clippard Instrument Laboratory, long a pioneer in the miniature pneumatic industry, has achieved a breakthough in proportional valve technology with the introduction of the EVP series proportional valve. Since 1974, Clippard ( has produced the EV series valve, said to combine
  • Proportional Valves Gives Precise, Variable Flow
    Proportional pneumatic valves can have hysteresis levels as high as 15%, which can wreak havoc on closed-loop control systems. Another problem with proportional valves is that they often vary from one to another in terms of maximum flow and gain. Gain is the rate of flow change to valve input
  • The Advantages of New Proportional and Servo Valves with Integrated Digital Electronics
    The paper presents a new generation of proportional and servo valves with integrated digital electronics. The micro controller allows with its free programmable signal processing options a significant improvement of the dynamic and static performance of the valves. Selected examples demonstrate
