TECHNICAL CHARACTERISTICS
Hydraulic regulator series 330 is a closed-circuit device which, when coupled with a pneumatic cylinder allows to obtain uniform advancing speeds with precision regulation. To couple in parallel it is advisable to choose cylinder SERIE 310 WITH GUIDED PISTON.
versions with parallel tank: * piston rod out-stroke regulation – piston rod in-stroke regulation – double regulation
versions with in-line tank: piston rod out-stroke regulation
controllable load: max. 800 Kg. (including inertia of the moving mass)
controlled speed: min. 40 mm/min max. 12 m/min
temperature: -10°c ÷ +80°c
fixings: same fixings are provided for series 309 and 319
*All the versions are available with the following pneumatic control devices: rapid nearing (SKIP), normally open stop (STOP), normally closed stop (STOP-NC). Electrical control devices on request.
