Product Description

PTFE and elastomeric spring energized seals For Valve

SPT SEALS COMPANY manufactures PTFE and elastomeric spring energized seals and sealing systems. Spring Energized Seals can be used in static, reciprocating and slow to medium rotary applications. Unli`ke many other seals where you must size your seal application around standard size seals, Spring energized seal can be manufactured to your product. While standard size seals are something we make everyday, we make seals in any size needed. Used as piston, rod, or face seals, the SPT(SI PAI TUO) spring energized seal is engineered to meet your exact specifications and design intent.

spring energized oil seal

Spring energized seals are designed to handle a wide range of applications where traditional elastomers fail. It excels in applications with high-speeds, wide temperature ranges and those with corrosive media. The Spring energized seal is a sealing device consisting of a PTFE or other polymer, energized by a corrosion resistant metal spring.  When the seal is seated in the gland, the spring is under compression applying force on the gland sealing surfaces thereby creating a tight barrier to prevent gas or fluids from leaking.  The spring also provides resiliency to compensate for seal wear, gland misalignment or eccentricity.  While spring force provides adequate force for sealing at low pressure, at high pressure the system pressure augments the spring force to provide an even tighter seal.

Spring energized seals design is based on three principles:
High-performance, engineered materials
U-cup style seal jackets
Metal spring energizers 

MATERIALS
SAIXUAN combines material technology and seal design to optimize your sealing performance. The material technology uses high performance engineered polymers made from PTFE, PEEK, Polyimides,other polymer materials specified for your application.

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.
