Component Specifications

Definition
A precision-engineered sealing component designed specifically for drain valves in industrial machinery, creating a tight barrier between mating surfaces to prevent leakage of liquids, gases, or contaminants. It ensures proper valve operation by maintaining pressure integrity and preventing environmental contamination or product loss.
Working Principle
Works by compression between two mating surfaces (valve body and drain port), creating a physical barrier through elastic deformation. The seal fills microscopic imperfections in the surfaces, preventing fluid passage through the interface while allowing controlled drainage when the valve is opened.
Materials
Nitrile rubber (NBR), Fluorocarbon (Viton/FKM), Ethylene Propylene Diene Monomer (EPDM), Polytetrafluoroethylene (PTFE), Silicone, or Metal (stainless steel, copper) depending on application requirements for temperature, pressure, and chemical resistance.
Technical Parameters
  • Hardness 70-90 Shore A
  • Inner Diameter Matches valve drain port
  • Outer Diameter Based on flange dimensions
  • Compression Set <25%
  • Pressure Rating Up to 150 psi
  • Temperature Range -40°C to 200°C
  • Thickness Tolerance ±0.1mm
Standards
ISO 3601, DIN 3770, ASTM F104, SAE J515

Frequently Asked Questions

How often should drain valve seals be replaced?

Replacement intervals depend on operating conditions, but typically range from 6-24 months. Factors include temperature extremes, chemical exposure, pressure cycles, and mechanical wear. Regular inspection for compression set, cracking, or deformation is recommended.

What materials are best for chemical resistance in drain valve seals?

PTFE offers excellent chemical resistance across a wide range. Viton/FKM handles fuels and oils well. EPDM is suitable for water and steam applications. Material selection should match the specific fluids being handled.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
