The field of electronics has come a long ways in the last century. Once we used vacuum tubes, but now we typically use solid-state technology. Digital electronics chips have eroded usage of their older analogue counterpart. Computer processors consisted of tens of transistors where today multi-core microprocessors are compact and much more powerful.

  1. The torque output is easily changed by adjusting the air pressure setting. The single position design assures re-engagement of the drive, from a complete stop, in the same position every time, thus providing exact timing of both components.

  2. These proven pneumatic performers are an obvious replacement for electro-magnetic clutch brake units offering significant economic advantages in operating costs

  3. Norman G. Clark - The Horton VMaster Viscous Step-Up Gear Drive System is designed for engines with crankshaft mounted fan drives, requiring additional cooling performance.

  4. Norman G. Clark - Batch Spear Holders are proudly manufactured in Australia by Norman G. Clark. Also referred to as a safety chuck, they are suitable for use in any application where repituous winding or unwinding of any flexible material takes place

  5. Norman G. Clark - Q-Shield™ is a patented technology that significantly reduces the consumption of diesel fuel or gasoline in internal combustion engines.

  6. Norman G. Clark  - Manufactured by Nexen, Eclipse servo brakes have more braking force making servo applications safer with at least 20-50% more torque than competitive brakes.

  7. Norman G. Clark - Index Heavy-Duty Pressure Switches are ideal for a wide range of heavy vehicle and equipment applications where durability and reliability are crucial.

  8. Norman G. Clark - Rotating Unions are used in many manufacturing processes to cool, heat or transfer fluid (pneumatic or hydraulic) power.

  9. Norman G. Clark - The Expello Pneumatic Drain Valve is fitted to each Stark Air Dryer/Purifier. It is actuated either by an electrical signal or pneumatically by the unloading of the compressor.
