TURBEL is an electrohydraulic operating device, built to generate a linear thrust along a stroke. It is used as an actuator for the opening/closing of electrohydraulic brakes, both for drum and disc brakes. All the thrustors of the TURBEL range are designed according to the DIN 15.430 standard in terms of force, stroke, fastenings and general dimensions.
The thrustor can be placed both vertically (electrohydraulic drum brake models NDT, NDT-V, NAT, NFT and all electrohydraulic disc brakes) or horizontally (electrohydraulic drum brake models NDT-A) in the brake.
The name of the TURBEL model gives us the information about its force and stroke. An example would be the TH-I-256:
- TH-I: it refers to the size of the TURBEL. Antec offers three different sizes: TH-I, TH-II, TH-III
- 25 refers to the Force: 250N
- 6 refers to the stroke: 60 mm
The ANTEC Turbel range offers forces between 250 and 4.000 N and strokes between 60 and 120 mm.
Thrustors can be equipped with any of the following options:
Inner spring (C)
The turbel can be equipped with an inner spring, so that in certain applications a return force of the piston can be ensured.
Lower force values to assure the return of the piston are also available under request
Limit switches (CSA)
Mechanical or inductive limit switches can be fitted to electrically signal the end position of an open Turbel.
Descent Valve (VD)
The TURBEL may be equipped with descent retarding valves (VD). By turning the lever on the valve (only 90º) the piston descent time will be delayed.
Low temperature (BT)
Turbel for working at low temperature conditions (-25ºC up to -40ºC)
High temperature (AT)
Turbel for working at high temperature conditions, between 50ºC and 70ºC
ATEX Version (ATEX)
ANTEC offers ATEX version Turbels for explosive atmospheres. The characteristics of these thrustors are the same as the standard version, but the dimensions are different.
