Component Specifications

Definition
A flexible, pressure-responsive diaphragm component within a starch slurry pressure control valve that modulates fluid flow by deforming in response to pressure differentials, maintaining consistent slurry viscosity and preventing blockages in food manufacturing pipelines.
Working Principle
Operates on pressure-balance mechanics: upstream slurry pressure deforms the diaphragm, which adjusts the valve orifice area to regulate downstream flow. This maintains constant pressure drop across the valve, ensuring uniform starch slurry delivery.
Materials
FDA-compliant elastomers (EPDM, silicone, or fluorocarbon) with food-grade reinforcement fabrics; thickness: 1.5-3.0mm; temperature range: -20°C to 120°C; chemical resistance to starch solutions and mild sanitizers.
Technical Parameters
  • Diameter 50-200mm
  • Cycle Life >1 million cycles
  • Hysteresis <2% of full scale
  • Response Time <0.5 seconds
  • Pressure Range 0.5-10 bar
Standards
ISO 5208, DIN 3356

Frequently Asked Questions

How often should control diaphragms be replaced in starch slurry systems?

Replace every 12-18 months or after 1 million cycles, whichever comes first, to prevent fatigue failures that could disrupt slurry consistency.

Can this diaphragm handle high-sugar starch slurries?

Yes, fluorocarbon versions resist sugar crystallization and microbial growth, maintaining flexibility in high-Brix applications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
