PPI 166 - Air Valve Detail.pdf

This document is a technical schematic illustration depicting two types of control valves used in pneumatic or fluid systems: a modulating control valve and an open-close control valve. Each valve is shown in plan and elevation views with detailed component labeling and connection specifications.

The modulating control valve features a 1/4" N.P.T. signal pressure connection and 1/4" N.P.T. supply pressure connection for proportional flow control. The open-close control valve includes a 1/4" N.P.T. supply connection, 3/8" N.P.T. exhaust outlet, and accommodates 1/2" conduit connections for integration into larger systems. Both valve designs show cylindrical actuators mounted vertically above horizontally-oriented valve bodies with flanged connection ports at the base. The technical drawing provides dimensional and interface specifications suitable for procurement or manufacturing documentation in an industrial control systems context.
