HYDRO-PNEUMATIC CYLINDERS
They Hydro Pneumatic Cylinders represent a novel technology, where two applied techniques, namely, the speed of pneumatic action and the force developed by hydraulics is combined to impart the key features of a production machine.

Invariably cylinder and Power-presses have a primary requirement of Fast Approach, Power Stroke and Rapid Reversal. Hydro-pneumatic cylinders satisfy these conditions perfectly. The rapid approach and reversal is accomplished by air, whilst the Power stroke is automatically actuated by the intensified hydraulic oil.

Why consider H-P Cylinders ?
	Compact and clean design
	High Stroke frequency
	Low approach forces governs Soft touch on your tooling
	Works on 6 bar shop-air, with simple pneumatic controls
	Low noise level
	Low installation cost.

Ideal Applications of H-P Cylinders
	Sheet metal working such as trimming, Embossing, shallow drawing, Riveting -Locking or clamping applications
	Compacting and moulding applications
	Assembly-maintenance and robotics applications.

Excellent Design Features
	The piston rod is supported at both ends - provide good rigidity.
	Seals of reputed makes such as Busak&Shamban, Merkel
	The piston rod movement is cushioned at both ends - reduces noise level and shocks.
	Tonnage Regulator - ensures process and tool safety.
	High pressure measuring connection - which can be used to monitor the process and actuate automatic production cycle. A pressure gauge at this point is a standard supply.
	**The changeover of the fast approach action to the working stroke is automatically actuated by a pneumatic valve, which is preset for optimum results.
	The oil chamber is maintained under mild spring pressure - this improves stroke frequency, permits installation in any orientation and saves on air consumption.
	Distinct separation of oil and air chambers - ensures air/oil separation - enhances reliability, helps in trouble shooting.
	**Pneumatic Control Gear used is Festo make
**(Applicable only when cylinders are ordered inclusive of controls)

SIZING-CONTROLS-ORDERING SPECS

Tonnage Capacity, Total Stroke, Power Stroke
Cylinders can be ordered with or without Controls

Operating Controls
	The Cylinder operates like any normal Hydraulic or Pneumatic Cylinder, where two ports are provided to move the cylinder in forward or reverse direction.
	In case of HP cylinders, a third port is provided, this port is pressurised to actuate the Power stroke. During reversal, this port is released to atmosphere.
	The above sequencing can be achieved by various methods. Considering the requirements and cost implications a suitable circuit may be adopted
	Providing flow control valves on the ports can control the idle forward speed and the reversal speed.
	For Smooth functioning and long seal life, an FRL unit in the air supply line is very essential.
