They operate using air or process gas pressurized with oil as the driving force. Available in low (250-500 psi) and high (600-3000 psi) pressure versions. They use gas as the driving force, propelling liquid, industrial hydraulic oil, and biodegradable oil. They use the H and EH series valves and are suitable for gate, ball, plug, butterfly, and damper valves.

They incorporate mechanisms such as symmetrical or canted Scotch yokes, rack and pinion, valve stems, and piston-type linear valves. They require instrumentation and accessories such as solenoids, limit switches, filters, regulators, pressure gauges, high and/or low pressure pilots, electrical switches, bypass valves, maintenance valves, eutectic devices, partial testing devices, storage tanks, hydraulic power units, local pushbuttons, remote pushbuttons, controllers, PLCs, communication protocols, fire protection, among others.

Operating times of 1 sec/in or less. Includes a manual hydraulic pump. Ideal for pipelines transporting gases or liquids where the same substance cannot be used as motive power. Perfect for pipeline shutoff and sectioning valves.
