No external Tubing is Required from valve to cylinder port. Only one Inlet pressure port has to be connected to the valves inlet port. This type of cylinder is usually used to operate Butterfly valves. 2

Also Top cover is provided with a circular opening at the back duly fitted with wire mesh for dust protection. This larger circular opening is provided for faster exhaust of the cylinder in the forward & Reverse stroke. Dimension of Balancer Cylinder available on request only as most of the cylinders are made as per Individual clients requirements. 3

6 COMPRESSED AIR CONSUMPTION Unit : lpm percycle Note : 1 cycle comprises of 1 forward and 1 return stroke of a standard pneumatic cylinder. The stroke length of the cylinder considered in this table is 100mm. Bore (mm) ROD (mm) Area (mm ) A B Operating pressure (Bar) Let us assume we have three cylinder working independently in different circuits. Cylinder A : mm Bore, stroke length 75mm operating at 12 cycles / minute Cylinder B : 80 mm Bore, stroke length 0mm operating at 10 cycles / minute Cylinder C : 0 mm Bore, stroke length 900mm operating at 13 cycles / minute From the table given above the air consumption at 6 bar working pressure of the cylinder would be Cylinder A : 0.6 x12cycles/min. x1.1( fos) = 8.34 lpm Cylinder B : x2.5(multiplication factor) x10cycles/min. x 1.1( fos) = lpm Cylinder C : 42.8 x9(multiplication factor) x13cycles/min. X1.1( fos) = 58 lpm Fos : Factor of safety (10%) FORCE CONSIDERATION : Selection of cylinder is based upon the bore, stroke & the piston rod diameter. This is further based upon the force required to do the work & distance to be traversed. The force available at a certain pressure is determined by the following chart.

12 MIDGET CYLINDER SERIES T MIDGET CYLINDERS Series - T cylinders are available in bore sizes of mm. Higher bore sizes of upto mm are available on request. These cylinders have improved aesthetic quality as compared to Tie rod mounted cylinder. Also as the front cover is threaded to the tube, seals can be easily replaced. Cylinder can be directly neck mounted as the front / rear covers are threaded reducing system installation time. *Available in non-cushioned & fixed cushioning type.

17 ISO 6431 PNEUMATIC CYLINDER : MOUNTING REED SWITCH For Magnetic cylinders only Function : The Reed switch is mounted on the tie rod of the pneumatic cylinder. It is used for proximity sensing of the magnet present on the piston of the cylinder. The reed switch sends an electrical impulse to the solenoid valve / other control device when the piston approaches the sensing position. Model : LSBD2 PM (WITH LED) Note : Model : R1 (WITH LED) 1) When inductive loads are switched, a high voltage peak is produced at the moment of switch - off. For this reason, proximity switch must be provided with a protective circuit. 2) The cylinder with magnetically actuated reed switches should not be fitted at places where there are strong magnetic fields.

22 SERIES 10 : HYDRAULIC CYLINDER Hydraulic Cylinders find their application in FLUID POWER when Force requirement is on the higher side. They are sturdier in construction as compared to pneumatic cylinders and are preferred when jerk free motions are required. These cylinders are available in different shapes & sizes to suit client applications. Series 10 - Square construction assembled and bolting using Tie rods. Simple construction enables easy change of seals. Available in Bore sizes of mm to 0 mm and pressure up to 2 Bar. Mounting accessories can be provided on such as Flange, Pivot, Foot brackets, Trunion etc. Cushioning possible on both ends. Different types manufactured in this series. Double Acting - Forward and return motion by oil. Single Acting - Forward stroke by oil & return by load exerted on the piston rod. SERIES 10 : Features - Cushioning possible at both ends to reduce impact at the end of the stroke. Material of construction - Tube - Carbon Steel duly hard chrome plated. Seals - Fabric reinforced. Covers - Steel Piston - Steel. Piston Rod - En8 hard chrome plated.
