We offer a complete range of Pneumatic Cylinders that include :

Standard Pneumatic Cylinders

Our standard range of pneumatic cylinders are available in Bore sizes ranging from 6mm diameter to 350mm diameter with strokes starting from 15mm to 1000mm long. These pneumatic cylinders are made of hard chrome plated heavy duty seamless tubes, C.I. end covers, hard chrome plated EN-8 piston rods and high quality neoprene/nitrile seals.

ISO Pneumatic Cylinders

Pneumatic cylinders are made as per ISO pneumatic cylinders 6431 standards. ISO Pneumatic Cylinders are available in Bore size starting from 32mm and with all types of ISO Pneumatic Cylinders mountings.

Special Construction Pneumatic Cylinders

These pneumatic cylinders, like our SPMs, are made as per client's requirement. Some examples of these pneumatic cylinders are: Magnetic Reed Switch-Type Position Sensing Pneumatic Cylinders, Hollow Shaft Cylinders, Stroke Adjustment Cylinders, Tandem Cylinders, Impact Cylinders, Continuously reciprocating Pneumatic Cylinders, Pneumatic Cylinders Special Construction Cylinders, Large Bore - 350 mm Cylinders etc.

Air Blowguns, Push Button Air Blowguns, Air Blowguns With Air Amplification Nozzles, Air Blowguns With Lever, Air Blowguns With Lever and 4" Long SS Nozzle.

Application of Air Blowguns :

For blowing off dirt, dust, oil etc. from shop floor, surfaces, machine working area, deep holes, crevices, geometric patterns, etc. and any hard to reach places. While a 3mm standard nozzle is part of the guns we can instead provide any of the Nozzles described in Nex Flow portion of this catalog ahead at an extra cost.

Construction of Air Blowguns :

Rugged construction, built to last. Air Blowguns are machined from solid Aluminium bar-stock with all other parts of Brass. Due to its ergonomic design the air blowguns easily fits in the palm of the operator's hand. Even continuous operation does not cause any fatigue to the operator.

Operating Condition of Air Blowguns :

Clean dry Air at 2Kg / Cm2 to 8Kg / Cm2

Material of construction of Air Blowguns :

Body : Bar Stock Aluminium.

Nozzle, Plunger and Nut : Brass

Seals and 'O' Ring : Nitrile Rubber ( Viton can be made availabe for special cases, at extra cost)

Pneumatic Timers

Part of many pneumatic circuits. These are used to provide a time delay of 1 to 10 or 3 to 30 or 10 to 60 seconds in a pneumatic circuit.

Pneumatic Control Valves

Directional Control Valves

Our simple but rugged design DCVs have found wide acceptance in the industry for more than two decades as they can perform in the toughest of working environments. Directional Control Valves are available in sizes ranging from 1/8" to 1" BSP. These DCVs can be operated by a range of Manual, Machine, Solenoid or Pilot operations.

Compact Solenoid DCVs

They are available in 1/8" BSP and 1/4" BSP port sizes. These compact DCVs are ideal for applications where space is a major constraint. Due to their sophisticated design these DCVs consume very little power, they operate on only 3 Watt of DC power. These DCVs can be assembled into gangs of pneumatic valves tailor made for your application.

Non-Return Valves

Simple and rugged design Pneumatic Valves these are available in sizes 1/4" to 1" BSP. They are used in applications where uni-directional flow is required.

Flow Control Valves

They find application in pneumatic circuits where finite flow control of air is required. The unique design of KJN Flow Control Valves does away with the cumbersome locknut required in valves of other make. Flow Control Valves are available for port sizes ranging from 1/8" to 1" BSP.

Quick Exhaust Valves

These find application in a pneumatic circuit where unrestricted, direct exhaust from a pressurized system is required. Example of such an application would be increased speed of a cylinder piston by allowing quick exhaust of the back pressure on the piston. Quick Exhaust Valves are available for port sizes ranging from 1/16" to 1"BSP.

Pneumatic Rotary Valves

Pneumatic Rotary Valves is a type of DCV. Pneumatic Rotary Valves are available in 2-way, 3-way or 4-way constructions with a knob or handle for operation. These find application in instrument pneumatic rotary valves, control panels, air-started generators, material handling equipment, etc. Pneumatic Rotary Valves are available in 1/4" to 1" BSP port sizes.

Special Application Valves

We have developed many pneumatic rotary valves for special applications. Some of the most common Pneumatic Rotary Valves are listed below :
Rotary Switch Valves : Similar to Pneumatic Rotary Valves in construction, it has a common outlet and four inlet ports or vise a versa. The Switch provides selection of connecting any one inlet with one outlet per position.
Key Operated Valves : Essentially a spool type DCV. These pneumatic rotary valves are made mainly for applications where unauthorized or erroneous control panels is to be prevented.
Automatic Signal Lock-up Relay : These are relays which auto-matically lock-up the transmitted signal when the supply pressure falls. They are mainly used with Diaphragm Control Valves to maintain position when supply pressure fails.
