Custom Solenoids and Valves for Pulse Width Modulation
Pulse Width Modulation (PWM) is a DC supply voltage that is switched on and off at a given frequency for a modulated period of time (duty cycle). Typical uses of a PWM-controlled solenoid are proportional hydraulic or pneumatic solenoid valves (digital control) or proportional current control (position control).
Proportional Pneumatic Control Valve
This pneumatic control valve was designed to meter inlet and outlet pressure to proportionally control an actuator.
