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.
