Description

Fisher 3620JP

Fisher 3620JP is an electro-pneumatic valve positioner that converts a 4–20 mA input signal into pneumatic output to drive the actuator for stable modulating control. It supports compact actuator-mounted installation and helps improve positioning consistency in demanding process loops.

Key Features

•4–20 mA DC input (up to 30 VDC compliance).

•Max supply pressure: 150 psig (10.3 bar) or actuator rating, whichever is lower.

•Supply media: Air (not approved for natural gas supply for this family).

•Actuator-mounted design for compact field installation.

•Multiple hazardous-area certification options available by configuration.
