Salt exposure, valve duty and shipboard controls shape a marine spring-return assembly. THINKTANK discusses the engineering decisions from materials to commissioning.

Tunnel damper actuation depends on the smoke-control sequence, airflow load and mounting arrangement. THINKTANK explains how these conditions shape the actuator selection.

Fuel isolation and cooling continuity need different fail positions. THINKTANK explains the torque, timing and control decisions behind a data-center spring-return valve assembly.

Smart valve positioners are widely used with pneumatic control valves to improve positioning accuracy, response, diagnostics and communication with plant control systems. The following table

When a control valve will not fully close, do not start by adjusting the positioner. Start with one simple field check: Does the valve stem

This guide explains the basic setup and automatic calibration procedure for a Fisher FOUNDATION Fieldbus valve positioner using a handheld communicator. Before starting, confirm that
