The FUJIKIN FPR-UBF-916-6.35 is a heavy-duty industrial pneumatic process valve engineered for high-purity and corrosive fluid handling in demanding process systems. It utilizes a normally closed, air-to-open pneumatic actuator with a 6.35 mm (1/4 in) tube connection, providing tight shutoff and repeatable flow control without electrical components in the fluid path.
