During development of its indicator valve, Kiene recognized that a new design concept was necessary to improve the operational characteristics of the valve. The major problems were (1) restrictive installation space, (2) valve seat deterioration due to high combustion temperatures, and (3) uncontrolled valve opening.
The installation of conventional indicator valves required a clearance in excess of 3 inches. By redesigning the gas passage and using a 60 degree valve stem angle, Kiene produced an indicator valve requiring only 1 5/8 inches of clearance for installation purposes.
A new concept in valve seat and valve stem design eliminated valve seat deterioration by shielding the seat area from the high combustion temperatures inherent in diesel and natural gas engines.
Kiene indicator valves features an original concept of "opening against and closing with engine cylinder pressure", so that any movement of the valve stem due to engine vibration, tightens the valve stem against its seat, excluding the possibility of the valve opening during engine operation.
All Kiene V-Line and A-Line Valves feature low initial cost, trouble free performance and ease of operation. Kiene valves have endurance and reliability unmatched by other valves available today.
