VALVE LAPPING & GRINDING
It is the process of smoothing out the engine valves so that they are effectively able to seal in the valve seat in the cylinder head to completely seal the engine's combustion chamber.
Purpose
Portable Valve Grinding and Lapping Machines are designed for In-Situ grinding and lapping of Body Seat and Wedge Seat of Gate Valves, Parallel Slide Valves and Swing Check Valves without dismantling the valves from the pipeline. These portable gate valve lapping machines are also suitable for shop floor and repair bay applications.
Features
Portable, yet durable:
HYDROTORC unique lightweight In-Situ Grinding and Lapping Machines are built tough so they can stand up to years of use.
Exact Angles:
Our Grinding and Lapping Machine automatically sets itself to the correct sealing surface angle due to universal joint in its design, making it suitable for any make of Gate Valves.
Perfect Grinding and Lapping:
Grinding heads on HYDROTORC In –Situ Valve Grinding and Lapping machines are individually driven discs, permitting rapid and efficient grinding of exceptionally smooth, flat surface for tightest possible seats. Since these grinding heads rotates many times during one rotation of the holding plate the surface is perfectly ground, using first coarse and then fine abrasive paper.
Design:
Our Grinding and Lapping Plates have five planet arms instead of the usual six, which ensures that all five discs are in contact with the work surface during operation.
Drive Available:
All models are available with either Pneumatic or Electric Drive.
Wet or Dry Lapping:
All models can be used with either Abrasive Paste (wet lapping) or Abrasive Paper (dry lapping) by simply changing the grinding discs.
Stellited Surface:
Grinding Stellited surface with CBN discs is also possible with our machines.
Suitable for all pressure class:
Our machines are suitable from ASA 150# to ASA 4500# class of valves.
Sizes:
HYDROTORC In-Situ Gate Valve Grinding and Lapping Machines are available in standard dimensions from size 15mm to 1800mm (See Below for more detail). Nonstandard sizes are also available on request. We regularly manufacture custom make machines as per client’s requirement.
