The ENV series of motorized needle valves for proportional flow rate adjustment combine the accuracy and repeatability benefits of a stepper motor with the linearity and resolution of a needle valve.
The result is adjustable flow control with less than 2% hysteresis, 0.1% repeatability and 0.2% resolution - making these valves ideal for consistent, high-performance delivery of gases and liquids in medical, life science and advanced-automation applications.
