Gearbox

Mirab Industrial Group (Privately held co.) started its activity in 1979 with the production of all kinds of industrial valves and related equipment.

Relying on technical knowledge and extensive experience over several decades of production and in response to the needs of the industry, it was decided that the Quarter-turn Gearboxes which are applicable in its manufactured valves, offers separately in several sizes and designs to the target industries.

Model: MGAL05, MGAL07, MGDI10 ——————————- Output Torque (Nm) : 125-500

Model: MGS50, MGS63 ,MGS80 ,MGS100 ——————— Output Torque (Nm) : 500-4000

Model: MWG130 ,MWG170 ,MWG210 ,MWG270 ———– Output Torque (Nm) : 12000-84000

Model: MGS320 ,MGS410 ,MGS512 ——————————- Output Torque (Nm) : 90000-360000

Functional Test:

All gearboxes are produced and tested in the Mirab co. Functional test is done by applying with minimum double of the torque which is required for input for the maximum output torque.

Degree of Protection:

All gearboxes are certified to IP65 & IP68 grade according to IEC 60529 standard.

Lifetime:

The Lifetime of gearbox in case of proper use and timely service and using the maximum output torque mentioned in the table, is at least 15,000 full cycles (open-close-open).The lifetime of gearbox can be increased, by less using of maximum torque output.

Gearbox Specification:

 Model MGAL: The swing angle of these gearboxes is up to 95 degrees, which can be adjusted independently with the outer screws of the gearbox housing after installation and lock with a nut.

Model MGS: The swing angle of these gearboxes is up to 95 degree, the start and stop end can be changed by independently adjusting the chuck nuts of the worm shaft. In these Gearboxes, torque is derived from worm shaft and worm wheel.

Model MWG: The swing angle of these gearboxes is up to 95 degrees, which can be adjusted independently with the outer screws of the gearbox housing after installation and lock with a nut.

Coating system:

 MGAL models with aluminum body are coated with black color epoxy powder paint and for other Models the cast iron body and cover after cleaning and shot blasting is coated with Grey (RAL7001) electrostatic epoxy powder paint.
