PLTC is a single working piston seal with corner reinforcement and anti-tilt function. This seal is able to take relatively high pressure from one side only. The back pumping effect is worse than PL type because of the very close contact of the corner reinforcement with the bore. Also the anti-tilt function makes the back pumping effect worse. The anti-tilt function is applied to prevent the seal from tilting in its groove with high speeds in combination with back pressure. It is only used in hydraulic systems. It can also be used in other fluids. It can be used in tandem systems as a primary seal but will need a pressure relieve channel in between the seals.
Max. Velocity is 5 m/s also depending on the material used and the medium it is working in.
