Seal that does not cause pressure buildup.
One of the problems that occurs when two seals are assembled in line on the rod of a hydraulic cylinder is the pressure buildup between the seals. To solve this problem, we have developed the Tacon Step Seal V. With its patented check valve function, it avoids pressure buildup between the seals, eliminating the need for previous buffer spaces or drain pipes.

basic information
Due to its high sealing capability and precise valve function, it prevents pressure buildup between seals when assembled in tandem, eliminating the need for the buffer space (oil reservoir) and drain pipe that were previously required between seals. Patented pressure relief check valve function Excellent resistance to protrusion Can accommodate a large radius gap Low friction Outstanding sealing performance during both fixed and moving states Difficult to experience stick-slip upon startup even after long periods of inactivity 【Specifications】 - Maximum diameter: up to 2600mm for rods, up to 2700mm for pistons - Operating pressure: up to 80MPa - Maximum speed during reciprocating motion: 15m/s, vibration 15Hz - Operating temperature: -45 to +200℃ (depending on O-ring material).
