Product Description
Product Overview
EPDM flange type DN100 rubber duckbill check valve designed for sewage discharge applications requiring exceptional corrosion resistance, abrasion resistance, and weather durability.
Installation Guidelines
Preparation
Verify installation environment compatibility including flange specifications, pressure rating, material composition, and rubber body suitability. Consider temperature, humidity, and media conditions.
Pipe End Inspection
Ensure pipe end face inclination deviation does not exceed 1% of pipe outer diameter or 3mm maximum for optimal flange connection integrity.
Flange Connection
Maintain flange perpendicularity with pipe center alignment. Flange parallelism deviation should not exceed 1.5/1000 of flange outer diameter or 2mm maximum. Use uniform specification bolts with single washers per bolt.
Gasket Installation
Install properly sized gaskets matching flange sealing surfaces. Buried pipelines require inspection wells for accessible flange connections.
Safety Precautions
Prevent pressure deviation during installation to avoid media leakage. Avoid installing flange connections within floors, walls, or casings.
Key Features & Benefits
- Automatic operation based on water pressure differential - safe and reliable performance
- Low water resistance with minimal starting pressure - automatically adjusts flow according to water pressure
- Excellent reverse sealing capability - zero leakage with enhanced backflow prevention
- Superior corrosion and aging resistance - extended service life with strong environmental adaptability
