Product DescriptionPTFE and elastomeric spring energized
seals For ValveSPT 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.SizeCustomizedPlace of OriginChina HebeiWorking

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
materialsU-cup style seal jacketsMetal spring
energizers MATERIALSSPT combines material technology and seal
design to optimize your sealing performance. The material
technology uses high performance engineered polymers made from
PTFE, PEEK, Polyimides, PPS and other polymer materials specified
for your application.SPRING ENERGIZED SEAL

different shape of spring seal/ spring energized
seal1.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.Applications & Industries Spring-energized PTFE Seals
