Features:
1. Limit switch boxes are easily adaptable for all quarter turn pneumatic actuators.
2. Rugged cast Aluminum housing for light eight, durability and provides protection for switch element.
3. Standard switch box is provided with two V3 micro switches pre wired to the internal block.
4. Individually adjustable and quick set cams for Open/Close switch operations.
5. The drive shaft dimensions are according to DIN-NAMUR standards.
6. Screwed in cover for ease of access (for few models only)
7. Position transmitters are available(optional)

Bevel gear boxes suitable for mounting and operating rising spindle valves.
These are thrust taking, maximum thrust 1000 kN. They are suitable for electric operation also. Stem covers are optional. Position indicating feature, locking device type can be provided.

For large thrust and torque bevel gear boxes are provided with primary spur gear boxes to reduce the rim pull. Torque ranges available 300 to 10000 Nm.

GH
GH series of gear boxes are used for operation of slurry valves. These gear boxes have provision of inline sheet grinding feature. These are normally provided with thrust base. These gear boxes can also be used for the rising spindle valves.

These are quarter turn pneumatic actuators used for quarter turn valves.

1. Rack and Pinion type


2. Scotch yoke type

For small torque models use rack and pinion (RP)type series actuators.

Scotch yoke type
Scotch yoke actuators are used for large torque models. The torque characteristics are more suitable for operating ball, plug and butterfly valves as it matches the valve torque characteristics.
These actuators can be fitted with following accessories.
Manual override
Limit switch
Solenoid valve
Quick exhaust valve
Positioners

Types available are:

Pneumatic automatic ball valves with all accessories are available both in floating and trunnion mounted design from class 150 to class 600 pressure ratings.

Metal seated ball valves and multiport ball valves are also available with actuators.
Fire safe ball valves are available in automated version.

Quarter turn manual valve actuator
These are the valve actuators used in the operation of Ball, plug and butterfly valves.
They are self locking, high torque, compact design.
They can be provided with locking arrangement. They can be used for electric operation with suitable flanges.

It is a manual worm gear type actuator used to operate quarter turn valves like ball, plug, butterfly valves and dampers.

Series MA: Torque ranges available are 500 to 2000 Nm
Series MB: Torque ranges available are 300 to 6000 Nm
MBGT for high torque output bevel gear boxes are provided with additional spur gear boxes at input side to reduce the input effort. Torque ranges available are 5000 to 2, 25, 000 Nm
