组件规格

定义
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.
工作原理
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.
材料
FDA-compliant elastomers (EPDMsiliconeor fluorocarbon) with food-grade reinforcement fabricsthickness: 1.5-3.0mmtemperature range: -20°C to 120°Cchemical resistance to starch solutions and mild sanitizers.
Diameter
50-200mm
Cycle Life
>1 million cycles
Hysteresis
<2% of full scale
Response Time
<0.5 seconds
Pressure Range
0.5-10 bar
标准
ISO 5208DIN 3356

常见问题

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.
