4. Working Technical Parameters
5. Core Features & Advantages
-
Dynamic Working Pressure: ≤ 20 MPa (200 bar)
-
Static Working Pressure: ≤ 40 MPa (400 bar)
-
Working Temperature: -200℃ ~ +260℃ (-328℉ ~ +500℉)
-
Max Linear Speed: ≤ 1.5 m/s (reciprocating motion)
-
Friction Coefficient: ≈ 0.04 (lubricated steel surface)
-
Applicable Media: Mineral hydraulic oil, lubricating oil, water, glycol, steam, chemical solvents, gas, vacuum and most corrosive media
-
Zero Crawling & Ultra-low Friction: Delivers smooth, jitter-free operation for low-speed and precision servo systems.
-
Extreme Temperature Resistance: Maintains stable sealing performance without deformation or brittleness in ultra-low and high-temperature environments.
-
Excellent Chemical Resistance: Tolerates acids, alkalis and various corrosive media, ideal for chemical, pharmaceutical and food-grade applications.
-
Long Service Life: Aging-resistant metal spring and wear-proof PTFE extend service life 3-5 times over traditional rubber seals.
-
High Vacuum Sealing: Satisfies high vacuum and low-leakage working standards.
-
Easy Installation: Integrated structure with positioning flange prevents torsion and simplifies assembly.
6. Application Industries
This seal fits precision hydraulic and pneumatic systems, servo cylinders, injection molding machines and construction machinery. It also applies to metallurgical, wind power, LNG cryogenic, chemical, pharmaceutical and vacuum automation equipment.
7. Interchangeable Alternative Models
-
RVM300200-T24S: Features higher wear resistance, suitable for heavy-duty high-pressure working conditions
-
RVM300200-T01S: Optimized for low-temperature and high-vacuum working environments
-
RVM300200-MF1: Adopts FDA-certified food-grade material for medical and sanitary equipment
8. Installation Notes
-
Keep the groove smooth and burr-free with edge fillet R≥0.3mm
-
Lubricate the seal with corresponding medium before formal installation
-
Install the seal with its U-shaped opening facing the pressure side
-
Match with rods of Ra 0.1-0.4μm surface roughness and HRC≥50 hardness
-
Do not twist the seal and spring during installation to avoid damage
