Custom Solenoids and Valves for Proportional Applications
Proportional solenoids and proportional solenoid valves are often used in applications requiring variable and precise control. By converting an electric control signal into proportional mechanical force, proportional solenoids are able to achieve varying position and force.
Discrete Proportional Valve System
Uses an intelligent combination of simple binary (ON/OFF) solenoid valves with varied port size to achieve stepped proportional control.
Proportional Pneumatic Control Valve
This pneumatic control valve was designed to meter inlet and outlet pressure to proportionally control an actuator.
Proportional Pressure Relief Valve
This direct-acting, normally open, proportional pressure relief valve can be designed to operate over various pressure ranges.
Three-Way Proportional Pressure Reducing-Relieving Valve
This proportional solenoid valve is a direct-acting, normally open, continuously variable pressure relief valve.
Canister Proportional Purge Solenoid Valve
This example of a pulse width modulated, proportional flow control solenoid valve is used in a vehicle's emission control system.
Proportional Solenoid Actuator
This proportional solenoid actuator (used to power proportional hydraulic valves in off-highway applications) is direct-acting and continuously variable.
