Advanced Concentric disc valve technology

Specially designed and adopted exclusively for NEC compressors, they ensure uninterrupted operation and long service life. As a result, you only need an annual shut-down for maintenance.

Manufactured on computerised SPMs, the perfect concentricity and flatness provides close tolerance and ensures a aerodynamic flow for low resistance. All of which means higher reliability, least valve losses & power savings.

Light weight piston & teflon rings

Special design light weight piston result in lesser inertia forces resulting in increased power savings and the ceramic filled teflon piston rings are higher wear resistant and hence have longer life.

One piece bearing suited for near life time operation

Shrunk fit bearings ensure proper alignment & clearance thereby reducing wear and tear. They have very high load bearing capacity. Ideally suited for high pressure piston compressors. Very high reliability & hardly needs replacement.

Overhung crank shaft for easy maintenance

Twin sleeve bearing on the crankshaft at the flywheel side to take the weight of the belt wheel. It is very easy to repair at customer site.
