Hoke 7G-Series two- and three-way instrumentation ball valves from Circor Instrumentation use a housing construction with metal seals and panel mounting as standard.

Hoke 7G-Series two- and three-way instrumentation ball valves from Circor Instrumentation use a housing construction with metal seals and panel mounting as standard.

Dynapak packing provides a leak-tight seal with low operating torque in vacuum or high pressure applications, helping to prevent fugitive emissions.

The valves offer bidirectional flow throughout their operating pressure range, with a maximum operating pressure of 207bar and a temperature range of -28 to +232C.

Suitable for handling viscous media, gas or liquids and with applications from hydraulic and high pressure test stands to pilot plants in refineries or chemical plants and measurement and regulating equipment, the G7 ball valves have metric Gyrolok end fittings.

Improved safety is ensured by visual indication of flow setting as the handle points to which port is in use or to the closed position.

Handle extensions up to 120mm are available to aid operation and easy position confirmation.

Pneumatic valve actuation for automated systems is an option by using a Hoke 07L rack and pinion actuator.

These actuators are available in double-acting and spring-return versions for 90 and 180deg actuation, as well as in a weather-proof or explosion-proof housing.
