Electric 3 way control valves provide automated mixing or diverting of process flow through a three-port design.

Triple offset butterfly valves provide low-wear metal sealing and reliable isolation for demanding pipeline service.

Pressure relief valves automatically discharge excess pressure to protect piping, vessels and process equipment.

Electric actuated diaphragm valves provide automated shutoff with isolated fluid handling and motor-driven operation.

Where slurry, sludge or solids-bearing media must be isolated remotely, an electric actuator allows the knife gate to be opened and closed without local manual operation. The gate travels through the flow path to provide direct shutoff while keeping the bore relatively clear when open. SVR Global serves projects seeking an Electric Actuated Knife Gate Valve Manufacturer in USA, with electrically operated designs suited to automated isolation and repeated cycling in demanding process lines.
