Valve seats refacers

Compression seal is one of the main factors which determine the efficiency of internal combustion engines. This makes the valves and their seats of fundamental importance and if they are worn the efficiency of the engine is reduced.

PROPER RECONDITIONING SHOULD RESTORE SHAPE AND SYMMETRY, MAINTAINING THE ORIGINAL LOCATION OF THE VALVE IN ITS SEATING, ELIMINATING DRAG AND GUARANTEEING PERFECT SEAL DURING THE PROGRESSIVE WEAR OF THE ENGINE PARTS.
THIS MAKES IT ESSENTIAL TO RESTORE:

Shape

• roundness : the seating must be perfectly round
• flatness : all the contact surface points must be equally level
• angle : the connection angle must be perfect

Symmetry

• concentricity : the seating must be concentrical to the axis of its guide and the shaft to the valve head
• verticality : the seating top must be vertical to the axis of the guide

Connection

• precision : there must be maximum precision in the location of the valve in the seat, maintaining the specified tolerance and the original cone

Special custom-made pilot pins

On request for all models.
On ordering supply the following data :

• I = guide length
• L = distance between guide and seat
• D = seat diameter
• H = seat height
• a = working angle
• d = guide diameter
