GEARBOXES
These gearboxes can be used both for electric actuation (motorised service) with the Centork multiturn actuators , or for manual actuation of the valves with a handwheel.
They are divided in 2 main groups, according to the type of valve to be actuated:
• Multiturn gearboxes, for linear valves (globe, gate, knife-gate, diaphgram).
• Quarter-turn gearboxes for rotary valves (butterfly, ball, plug and dampers).
The CENTORK multi-turn gearboxes are designed for actuation of valves with linear movement like the valves of floodgate, globe, tajadera, diaphragm or the floodgates of channel.
Can be used for:
- Electric actuation, by mounting Centork multiturn electric actuator Actuación eléctrica.
- The gearboxes are supplied with an actuator input mounting flange according to ISO5210 that allows a direct mounting.
- Manual Actuation, directly though handwheel.
- Pneumatic or Hydraulic actuation, though the mounting of Centork hydraulic or pneumatic multiturn actuators.
Main characteristics:
- Torque range from 60 Nm to 16.000 Nm.
- Gear Ratios from 1:1 to 24:1
- Output flanges and couplings according to ISO 5210.
- High degree of weatherproof protection IP67 (IP68 optional).
- High quality corrosion protection.
GEARBOXES - Quarter-turn Gearboxes
The CENTORK quarter-turn gearboxes are designed for the actuation of valves with a rotary movement of less than one turn, like butterfly, ball and plug valves and dampers.
Can be used for:
Electric actuation, by mounting Centork multiturn electric actuator Actuación eléctrica.
- The gearboxes are supplied with an actuator input mounting flange according to ISO5210 that allows a direct mounting.
- Manual Actuation, directly though handwheel.
- Pneumatic or Hydraulic actuation, though the mounting of Centork hydraulic or pneumatic multiturn actuators.
Main characteristics:
- Torque range from 280 Nm to 350.000 Nm.
- Gear Ratios from 40:1 to 3500:1
- Self-Locking movement from 90º to -5º. 180º or multiturn optional.
- Output flanges and couplings according to ISO 5211.
- Mechanical end stops easily adjusted.
- Bronze wheel optional for modulating service.
- High degree of weatherproof protection IP67 (IP68 optional).
- High quality corrosion protection.
