T25 Series – NAMUR Mounted 3/2, 5/2 & 5/3 Solenoid Valve

Product Overview

The T25 Series is a pilot-operated pneumatic solenoid valve designed for direct mounting onto pneumatic rotary actuators using standard NAMUR mounting dimensions.

The valve is available in 3/2, 5/2 and 5/3 configurations, providing flexibility for spring-return and double-acting actuator applications. Internal and external pilot options are available, alongside single solenoid spring-return and dual solenoid stay-put configurations.
