PTFE Spring Energized Oil Seal Rod Seal/Shaft Seals with Stainless Steel Spring¹

Product Description  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 Temperature-50oC~250oCMaterialPTFEApplicationPharmaceuticalsLiquid ChromatographyFood ProcessingSpace ExplorationTire ProductionHydraulicsVacuum ServiceOilfield Exploration and Production etcPackageplastic film bag and carton Model NumbercustomizedColorWhite, Blue, Brown, Black, Grey  spring energized oil sealSpring 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 MATERIALSSAIXUAN 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.SPRING ENERGIZED SEAL FEATURES Temperature: -268°C (-450°F) to +316°C (+600°F)Pressure: Vacuum up to 3448 bar (50,000 psi)Low and controlled frictionBroad chemical resistanceSpring-energized seals made of PTFE are characterized by:Low and high temperature resistance (-328°F to 500°F, -200°C to 260°C)FDA compliant compounds and designs availableExceptional resistance to chemicals and corrosionProvide the lowest coefficient of friction of all sealing materialsUnlubricated dry-running capabilities Pressure for standard designs up to 3,000psi (210 bar)High pressure special seal designs up to 20,000psi (1380bar)*Good service --- worth your trustFactory direct sale ----Customized service for you                                                      The 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.Energized PTFE Spring Seals:TypeUse forTechnicalApplicationMaterialSymmetricstandard heel groovetemperacture:-40~+260 °C ,speed ≤m/s:15,pressure≤ Mpa:45virtually all fluids,chemicals and gasesPTFE-filled stainless steelrodstandard heel groovetemperacture:-40~+260 °C ,speed ≤m/s:15,pressure≤ Mpa:45virtually all fluids,chemicals and gasesPTFE-filled stainless steelpistonstandard heel groovetemperacture:-40~+260 °C ,speed ≤m/s:15,pressure≤ Mpa:45virtually all fluids,chemicals and gasesPTFE-filled stainless steelsymetric for rodflanged heel groovetemperacture:-40~+260 °C ,speed ≤m/s:2,pressure≤ Mpa:25virtually all fluids,chemicals and gasesPTFE-filled stainless steelhigh-low lip rodflanged heel groovetemperacture:-40~+260 °C ,speed ≤m/s:2,pressure≤ Mpa:25virtually all fluids,chemicals and gasesPTFE-filled stainless steelinsideface sealtemperacture:-40~+260 °C ,speed:static or slow rotary,pressure≤ Mpa:45virtually all fluids,chemicals and gasesPTFE-filled stainless steeloutsideface sealtemperacture:-40~+260 °C ,speed:static or slow rotary,pressure≤ Mpa:45virtually all fluids,chemicals and gasesPTFE-filled stainless steelApplications & Industries Spring-energized PTFE Seals are suitable for service in the following industries:PharmaceuticalsLiquid ChromatographyFood ProcessingSpace ExplorationTire ProductionHydraulicsVacuum ServiceOilfield Exploration and ProductionPaint and SolventsSteel MillsAdhesivesCryogenic ServiceLiquid Handling SwivelsPumps and ValvesGas Production and TransportationSemiconductorsMedical EquipmentGas Handling EquipmentValve stem packing for wellhead equipment in PEEKcustomized Material:PTFE/PEEKStyle:Mechanical Seal Compound:PEEK/PTFE/UHMWPE/PCTFE Application:Hydraulic Temperature:-50oC~250oCPressure:≤60Mpa Standard or Nonstandard: standard Sealing PrincipleSPRING ENERGIZED PTFE SEAL APPLICATIONSOilfield Equipment,Compressors,Mechanical Seals Cryo Coolers, Hydraulic Actuators, Chemical Pumps Aircraft Engines,Brake Systems,Food Processing EquipmenDirection for useThis Vee packing set ,U-packing PTFE+FKM/FPM/NBR/HNBR Filled and the Spring loaded Filled PTFE  Stem Packing  are  Used for Cameron FC gate valves and FL gate valves Size Chart of V packing set U-packing and stem packing gate valve sealsName SizeU-packing 1-3/4 x 1 U-Packing;2-3/8 x 1-5/8 U-Packing,3-1/2 x 2-3/4 U-Packing;2 x 1-1/4 U-Packing;2-3/4 x 2 U-Packing;2 x 3.125 x 1.13;2-1/4 x 1-1/2 U-Packing;3 x 2 U-Packing;2.75x3.50x0.815Vee packing set /Stem packing set1/2*2-1/4; 2-3/4*23-1/2*2-3/4   Company ProfilePackaging & Shipping FAQQ1.
