Spring energized seal is a U-shaped PTFE seal ring, which is combined with an O-shaped or V-shaped special spring. It is a high-performance seal with a U-shaped PTFE seal and stainless steel spring. When the system pressure is zero, the spring provides the initial pre-pressure. When the pressure of the system increases, the U-shaped cavity is filled with pressure medium and the lip is pressed against the cylinder wall. This ensures that the seal is in the entire pressure change process. Always has a good sealing performance.
Spring energized PTD seal is outside face seal.A special O-shaped stainless steel spring end seal is installed in a sealed circle with an outward V-type PTFE.
