Provalve brand machines have been manufactured by Serdarlar Makina since 2008.
Serdarlar Makina Company was established in Turkey to manufacture machine tools for machining engine parts. Despite the success achieved, since 2008 the production of machines for repairing the lower part of the engine was closed and all attention was focused on its own line of metal-cutting machines and equipment Provalve for machining and repairing valve seats in cylinder heads.
The machines and equipment of this line received a strong, technologically innovative, yet simple design and an extremely wide range of performance characteristics. These machines for machining seats in cylinder heads were conceived to have the highest possible accuracy (air cushions with transverse movement), the most modern technology for machining and repairing cylinder heads, easy maintenance and truly competitive low prices for cylinder head repair equipment.
Provalve machines have unrivaled precision in machining cylinder head seats of any engine – from small motorcycles to diesel engines of heavy construction equipment.
The quality of manufacture and reliability of Provalve equipment is higher than its analogues, which is confirmed by the fact that the warranty for all Provalve machines is 2 years – in contrast to the 1 year warranty established by the vast majority of competitors.
Such high quality of Provalve equipment at a very affordable price makes these machines extremely promising for the markets of many countries. As a result, Provalve machines have become extremely widespread in Arab and African countries.
The Serdarlar Makina plant, which produces the Provalve machine line, is located in Ankara.
All Provalve machines for repairing valve seats in cylinder heads have a rigid system of fastening the tool to the spindle, cylindrical pilots for centering the spindle and standard Serdi-type cutters.
The Provalve cylinder head repair machine range from Provalve includes 2 main models of machines for processing seats and guide bushings – Provalve-1600 and Provalve-800 with 4 air cushions, having 5 modifications, including with different frame designs, with automation for particularly fast and high-precision centering, as well as with a touch screen. In addition, since 2019, the line has included Provalve PM series basket-type washing machines.
Due to their technical advantages (technical solutions used in Provalve machines are protected by patents) at an affordable price, Provalve machines for processing valve seats have virtually no competitors in the engine repair equipment market. This determined the widespread use of Provalve machines first in Arab countries, and then in Europe, where the main consumers of this equipment were workshops and engine repair shops.
Since 2017, cylinder head repair machines can be ordered in Ukraine, Kazakhstan, Uzbekistan and other countries.
Provalve factory in Ankara is one of those factories that have their own complete cycle of machine tool production — from the manufacture of individual parts to painting, assembly, adjustment and packaging.
