KV PISTON SEAL
KV is a piston seal a simple lip effect, energized by a corrosion resistant metal V spring. The asymmetrical profile, with the dynamic lip suitably drawn, short and stocky, ensures a reduction in friction and a long service life. The metal spring inside the throat guarantees a good sealing capacity even at low pressures. The possibility of combining different materials for the two components, it allows the use of the gasket in various fields: hydraulic, chemical, pharmaceutical and food.
