Fabric-Reinforced NBR Rubber Diaphragm
1️. Product Introduction
The Fabric-Reinforced NBR Rubber Diaphragm, manufactured by Anh Trí Tuệ Company, is a specialized sealing component used in diaphragm valves, pressure-regulating valves, air exhaust valves, air-operated diaphragm pumps, and pneumatic–steam–oil control systems.
The diaphragm is made from NBR rubber combined with a reinforced fabric layer, providing high mechanical stability, excellent oil resistance, and reliable sealing performance under pressure.
2️. Key Advantages
- Stable pressure sealing:
The rubber–fabric structure ensures tight contact with the valve surface, minimizing air, oil, or fluid leakage.
- Excellent oil and compressed-air resistance:
NBR material withstands mineral oils, engine oils, hydraulic oils, and oil-laden compressed air.
- High mechanical strength:
The reinforced fabric layer prevents tearing, deformation, and wear, while withstanding repeated compression cycles.
- Reliable performance in industrial environments:
Operating temperature range from –30°C to +110°C, suitable for pressure regulators, exhaust valves, and diaphragm pumps.
- Long service life – consistent operation:
High tear resistance and strong recovery properties reduce maintenance frequency and replacement costs.
