Product Description:
Material Properties
Common Materials:
- Rubber Types: Nitrile rubber (NBR), fluorocarbon rubber (FKM),
ethylene propylene diene monomer (EPDM), etc., offering oil
resistance, corrosion resistance, and high-temperature tolerance.
- Polyurethane (PU): High wear resistance, suitable for
high-frequency operation.
- PTFE (Polytetrafluoroethylene): Chemically inert, resistant to
strong acids and alkalis, ideal for extreme corrosive environments.
Selection Criteria: Choose based on the medium (e.g., air, water, oil, chemical
gases), temperature range (-40°C to 200°C), and pressure
conditions.
Physical & Mechanical Properties
Elasticity & Flexibility: Ensures fast response and sealing, minimizing hysteresis.
Fatigue Resistance: Withstands millions of cycles in high-frequency switching.
Wear Resistance: Reduces friction-induced wear, extending lifespan.
Tear Resistance: Prevents damage during installation or high-pressure shocks.
Structural Design
Single/Multi-Layer Construction: Multi-layer composite diaphragms (e.g., rubber + fiber
reinforcement) enhance pressure resistance.
Shape Compatibility: Matches valve body structure for proper sealing (e.g., flat or
corrugated designs).
Thickness: Typically 0.2–1 mm, affecting flexibility and durability.
Environmental Adaptability
Temperature Range: Varies by material; standard range is -30°C to 150°C, while
specialty materials (e.g., FKM) can withstand up to 200°C.
Pressure Range: Generally 0.1–1 MPa; high-pressure models require reinforced
designs.
Media Compatibility: Resistant to compressed air, steam, oil mist, or chemicals (e.g.,
ASCO 327 series diaphragms suit multiple fluids).
Lifespan & Reliability
Service Life: High-quality diaphragms last 1–5 million cycles under standard
conditions.
Failure Modes: Common issues include cracking, deformation, or seal failure due
to aging, overpressure, or chemical corrosion.
Applications
Typical Uses: Dust removal systems (e.g., bag filters), pneumatic control
systems, industrial automation.
Model Examples: ASCO 210 (general-purpose), ASCO 327
(high-pressure/corrosion-resistant). Note: Diaphragms may not be
interchangeable across models.
Maintenance & Replacement
Replacement Interval: Regular inspections (e.g., annually or per million cycles);
replace if hardening or cracks appear.
Installation Notes: Avoid twisting or overstretching; ensure sealing surfaces are
clean.
