The different shape of spring seal/ spring energized seal
1.V-spring seals are designed for used in high or low presseure dynamic reciprocationg or rotary applications.
2.Slanted Coil Spring Seals are for low friction, dynamic reciprocating and rotary applications. The seal produces a near flat load curve when compressed ( installed ). They provide constant predictable loads through their very wide deflection range.
3.Helical Spring seals are designed for used in static or slow, infrequent dynamic sealing application due to high compression load over a small deflection range, which make these seals suitable when low pressure or vacuum and very low temperature ( cryogenic ) are present.
