PTFE V-rings are used mainly for sealing on plunger and piston rods of hydraulic cylinders, presses, valve spindles and controls. Several sealing lips and the long contact surfaces ensure a good sealing performance. The seal sets consist of a pressure ring, a back-up ring and V-rings, which in number and design are adapted to the various operational conditions. This makes them more insensitive to contamination from the operating medium than one-piece seals. Further decisive advantages are their form stability, which make V-rings insensitive to pressure peaks, and their preload adjustability (spacer plates, springs). In addition, they have a favorable breakaway torque even after a long standstill period. Standard profiles are manufactured from pure PTFE or PTFE with fillers. There is an elastic design for the low pressure range, a design is available for a broad product spectrum, where the sealing function is given due to a wedge effect and a pressure resistant, relatively rigid design for harsh operating conditions. V-seal sets are made by machining and can be produced in a variety of diameters and heights. Medium pressure V-seal set (MDM) – Pressure range: < 50 bar – Elastic profile version High pressure V-seal set (HDM) – Pressure range: 50 to 100 bar – Profile relatively rigid, seals through a wedge effect Extreme pressure V-seal set (HöDM) – Pressure range100 bar – 250 bar – Preferable for static sealing functions and pulsating pressures
