White Knight’s patented shift cylinder pilot valves are the longest lasting pilot valves in the industry, and they offer higher reliability than traditional pilot valves. They utilize face sealing technology to ensure effective seals even as pumps undergo geometric changes caused by wear, pressure, and temperature.

The unique design of these pilot valves ensures diametrical wear of moving parts does not affect the valve or its seal because they open and close in a linear fashion congruent with pump movement without using linear seals. This allows the seals to be constructed of fluorpolymer materials rather than elastomers.

Other features that ensure reliability and long life of White Knight pumps include: Pneumatic Logic™ and stroke detection.
