Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice Hydraulic speed control cylinders Series 1400 - Ø40 - Ø63 3 Pneumatic actuation 3 | 121 Series 1400 - Ø40 - Ø63 The SKIP and STOP valves are pneumatically actuated 2 ways poppet valves. The SKIP valve (accelerating device) is normally open and is equipped with a supplementary regulator for maximum speed control; it must be activated to obtain speed regulation. The STOP valve can be normally closed or normally open. Construction characteristics Bore 40 mm and 63 mm diameter Barrel bright painted drawn steel Regulators group brass Waterproof seals NBR rubber Piston seals FPM Rod seal PUR Circuit oil hydraulic with viscosity 2.9° E at 50°C (viscosity index minimum 118) Pistons aluminium Piston rod C43 chromed steel End caps black anodised aluminium Tie rods zinc plated steel SKIP and STOP valves black anodised aluminium Operational characteristics Max connecting load 600 kg (Ø40) -1200 Kg (Ø63) Working temperature -5 °C ... +70 °C Min. and max. speed 60 ... 10000 mm/min. Minimum pressure for the actuation of SKIP and STOP valves 4 bar Attention: air must be dried for applications with lower temperature. Standard strokes 50 - 75 - 100 - 150 - 200 - 250 - 300 - 350 - 400 - 450 - 500 mm For minimum strokes see different types. On request are available strokes up to: 1300 mm Operation instructions Important: If the hydraulic regulator is mounted parallely with a pneumatic actuator, to avoid the bending moment on the rod generated when the stroke is adjusted or when the stop is engaged, it is recommended to guide and support the load to be moved. The limit pressure is indicated below, based on the size of the pneumatic actuator, above which it is recommended to guide and support the load: Cylinder Limit pressure (bar) Ø40 and Ø50 10 Ø63 5 Ø80 2 Over Ø100 always guide and support the loadTCAEITT Maintenance the speed control check is a closed system and there are no external factors that can adversely affect its function. care however, has to be exercised not to allow the hydraulic fluid level to drop below the minimum indicated on the auxiliary tank. Should this occur, cavitation, or worse, an air pocket would result causing erratic control. additional fluid should be put in exclusively through a unidirectional valve by means of an appropriate syringe (such as our code number 1400.99.01). excess fluid will be expelled through a vent into an appropriate container. it is necessary to completely disassemble the regulator and be sure to bleed the system to eliminate air pockets. We suggest that you create a vacuum before beginning to refill. this can be done with a small unidirectional valve turned up and repeatedly loaded with a syringe. the rod must be manually actuated successively releasing air through the valve using a small and pointed instrument.
