BUILT FOR DURABILITY. ENGINEERED FOR PERFORMANCE.
C-316 NAMUR Valves
The VERSA C316 NAMUR Series Valve is a compact, corrosion-resistant stainless steel solution designed for reliable performance in demanding environments. Engineered to mount directly to NAMUR actuators, this versatile valve is available in both 4-way and 3-way configurations—making it ideal for double acting or spring return actuator applications.
When used as a 3-way valve, the unused exhaust port transforms into an actuator vent, where a filter or muffler can be installed to block contaminants from entering the valve or actuator. Its 5-port design enables precise control of actuator speed and direction with the use of speed or bleed controls. For high-vibration applications, the double solenoid models feature a detent mechanism that maintains the last shifted position—ensuring consistent, stable operation.
