1. Product Advantages
- Superior Material Performance: Crafted from high-grade PEEK, the TVM Type Spring Energized Seal boasts exceptional heat resistance (operating temperature up to 260°C), chemical inertness to aggressive fluids (acids, oils, solvents), and outstanding wear resistance—ensuring long-term durability even in harsh conditions.
- Reliable Sealing Integrity: The spring-energized design compensates for dimensional variations and equipment wear, maintaining a tight, leak-proof seal across fluctuating pressures (0-30 MPa) and temperatures.
- Consistent Quality: Compliant with Trelleborg’s strict standards, each seal undergoes rigorous testing (pressure, leakage, material composition) to guarantee uniform performance, reducing maintenance frequency and downtime.
2. Working Principle
The TVM Type Seal operates on a spring-energized mechanism combined with PEEK’s inherent rigidity. When installed, the integrated spring exerts constant pressure on the PEEK sealing lip, forcing it to 贴合 (conform to) the mating surface. As system pressure increases, the fluid pressure further energizes the lip—enhancing contact force and sealing tightness. PEEK’s low friction coefficient minimizes wear during movement, while its chemical stability prevents degradation from media exposure, ensuring sustained sealing efficiency.
3. Product Details
- Material Specifications: 100% virgin PEEK (density: 1.32 g/cm³; tensile strength: 90 MPa), with optional FDA-compliant grades for food/pharmaceutical applications.
- Design Features: Precision-machined sealing lip (tolerance ±0.02 mm) for optimal surface contact; corrosion-resistant stainless steel spring (316L) for long-term elasticity; standardized TVM dimensions for direct replacement of Trelleborg original parts.
- Quality Certifications: ISO 9001, RoHS, and CE certified, with traceable batch numbers for full product lifecycle management.
4. Application Range
The Forever Seals TVM Type PEEK Seal is widely used in industries requiring high-performance sealing:
- Hydraulics & Pneumatics: Valves, cylinders, and pumps in construction machinery or industrial automation.
- Automotive: Transmission systems, engine components, and EV battery cooling circuits.
- Process Industry: Chemical reactors, pharmaceutical mixers, and food processing equipment (FDA grade available).
- Aerospace & Marine: Low-maintenance sealing for aircraft hydraulic systems or marine engines (resistant to saltwater corrosion).
5. FAQ (Frequently Asked Questions)
- Q1: Can this seal replace Trelleborg’s original TVM seal directly?A: Yes. Our TVM Type Seal follows Trelleborg’s standard dimensions and performance criteria, enabling drop-in replacement without modifying equipment.
- Q2: What is the maximum media compatibility?A: PEEK resists most industrial fluids, including mineral oils, hydraulic fluids (ISO VG 32-68), acids (pH 2-12), and alcohols. Contact us for custom compatibility checks with special media.
- Q3: What is the typical service life?A: Under normal operating conditions (25-200°C, 0-20 MPa), the seal offers a service life of 2,000+ operating hours—20% longer than standard PTFE-based seals.
