General

Automated Valves. Valves which are controlled by actuators attached to the valve stem. The actuators can be electric motors, solenoids, pneumatic, or hydraulic. Actuators can be used for automatic control, remote control, or because manual control is difficult.

Things to Consider: Actuation method: manual, electric, pneumatic, hydraulic; Valve motion: rotary, linear; Operation: on/off (isolating), modulating; Actuator torque range; Full range of rotary motion (degrees); Valve stem stroke length; Number of turns (for multi-turn actuators); Actuator force (seating thrust); Control signal input: current, voltage, pressure; DC voltage; AC voltage; AC phase; Air supply pressure; Hydraulic fluid supply pressure; Stem diameter; Actuation time maximum value; Failsafe state; Operating temperature; Hazardous or non-hazardous location, Agency approvals, Warranty.

  • SPEC #:17990

Globe

Automated Globe Valve: The same as a manual globe valve (see above), except that they normally use sliding stems, which are smooth rather than threaded, and are opened and closed by an electric, pneumatic, or hydraulic actuator assembly.

Things to Consider: Type of control (Flow or pressure), Actuation method, Valve size, Pressure rating, Media temperature, Flow (Cv), Connection, Metals used, Plastics used, Application name, Media description, Approvals and standards, Warranty.

  • SPEC #:17920

Needle

Automated Needle Valve: The same as a manual needle valve (see above), except the valve mechanism is moved by an electric, pneumatic, or hydraulic motor which is controlled by a remote switch or remotely generated electronic signal.

Things to Consider: Type of control (Flow or pressure), Actuation method, Valve size, Pressure rating, Media temperature, Flow (Cv), Connection, Metals used, Plastics used, Application name, Media description, Approvals and standards, Warranty.

  • SPEC #:17930

Plug

Automated Plug Valve: The same as a manual plug valve (see above), except the valve mechanism is moved by an electric, pneumatic, or hydraulic motor which is controlled by a remote switch or remotely generated electronic signal.

Things to Consider: Valve size, Pressure rating, Media temperature, Flow (Cv), Connection, Metals used, Plastics used, Actuation method, Application, Media description, Warranty.

  • SPEC #:17940

Solenoid

Solenoid Valve: An electro-mechanical device used to control the flow of liquid or gas by actuating an electro magnet or solenoid. These valves usually have either two or three ports. Two-port valves switch flow ON or OFF. Three-port valves direct flow between two output ports.

Things to Consider: UL listed, Fitting types and sizes, Construction & materials, Operating mode, State when de-energized, Maximum operating temperature, Coil rating, continuous duty requirments, Encapsulated coil, Voltage tolerances, NEMA rating for coil, Port size, Orifice size, Minimum pressure differential, Flow factor, Operation pressure, Coil power requirement, VA inrush, VA holding, Dimensions, Weight, Warranty.
