Material specification:

The standard worm actuator is built to our "weatherproof" specification SLO39 (according to
Protection class IP65, ambient temperature -40Â°C to 100Â°C). Here the actuatorâ€™s main components consist of the following materials (options in brackets):

Gearcase and cover
High-quality grey cast iron (or, alternatively, spheroidal graphite cast iron)
Quadrant
Spheroidal graphite cast iron (alternatively aluminum or bronze)
Worm
Hardened steel, up to size M83
One-piece worm and worm shaft of hardened steel, for size M125 to M200
Input shaft
Carbon steel up to including M83 (alternatively, stainless steel)
Seals
" o " rings of nitrille rubber on plain bearings at input and output (alternatively, lip seals on input shaft)
Input shaft bearings

Radial: bush bearings of oil impregnated sintered bronze, up to and including M83
Axial: up to M83 needle or ball bearings.
M125 to and including M200 taper roller bearing for radial and thrust.

Lubricant
No. 2 consistency grease, filled for life time service.
Paint
Primer paint suitable for all final paints having a synthetic base (special paints, e.g. epoxy primer on request)
Valve operators MTF50, M83, M125, M160, M200 with single combination of spur gears with motor adapters F10 should be post equipped with additional spur gear SI3,5. This spur gear has F 10 flanges on input and output and could be screwed to every F10 flange. Using additional spur gear SI3, 5 increase ratio about 3,5 times and factor 3,3 times.

Worm gearboxes for modulating regime:

Worm gearboxes for modulating regime are produced on the base of M - F or MFseries gearboxes and have the same dimensional and torque parameters including base flanges and shaft drilling dimensions. They could be with electric or hydraulic modulating actuators which are directly connected with base gearbox. Never use additional spur gears!

Gearboxes for modulating regime are marked similar like gearboxes of M – F or MF series. Only behind letter in size specification is added letter “ O”. for instance MOF40, MOCF72, MOFF36………….MOLF60. Letter “O” means that quadrant is made from special Sulphuric bronze with long life time and small amortization. Worm of this gearboxes is also from special steel which forced long time sliding friction and by this way long life of all gearbox.

Life time of this gearbox is designed to make 5,000.000 starts, that means impulses from actuator. Expression cycle is not used because during one working cycle could be several correction starts like to position open nor to position close. Gearbox corresponds to working regime from S1 to S4. Maximal number of starts during one hour is 1.200.

Gearboxes with raised positron indicator:

Gearboxes with dosed positron indicator are use din CASE when valve shaft is Langer then allowed height for selected type of gearbox. Dosed positron indicator could compensate lengths to 45 mm up standard height allowed for selected gearbox. And are use data gearbox series M – F, M, MF, MF-IS.

Dosed positron indicators are from cast iron, steel or plastic depends on lengths and gearbox type.

Gearboxes with switched input shaft about 90°:

M – F, MF, MF-IS series gearboxes could be equipped with additional bevel gear AP1 which could turn direction of input shaft about 90° from level of wormshaft. These combinations are used for buried service or for operating valve in not standard height.
