Main functions and technical parameters of the product
MeiDe Valve produces Resilient Seated Gate Valve ensures zero leakage (≤2ppm per ISO 5208) with EPDM-coated elastic gate for bidirectional sealing. Key benefits:
- Debris Tolerance: 8mm EPDM layer absorbs ≤6mm particles, auto-cleaning during operation.
- Corrosion Resistance: 250μm electrostatic epoxy coating (ISO 12944 C5-M) protects against chemicals/saltwater.
- Non-Directional Installation: Bidirectional pressure rating (PN25) eliminates flow restrictions.
- Flat-Bottom Seat Design: Prevents debris buildup, reducing 90% maintenance.
- WRAS/NSF 61 Certified: Safe for potable water systems. Ideal for wastewater, mining slurries, and HVAC pipelines.
