Product Description

Stainless Steel 4-Way Double Seat Mix Proof Mixproof Valve

A is a hygienic valve designed to prevent cross-contamination between two different product lines in food, dairy, and pharmaceutical processes. It uses dual-seat technology to isolate fluids, ensuring that one product does not mix with another. Leak detection chambers, automated control, and CIP compatibility make it ideal for clean and efficient production. Its robust design, smooth flow path, and sanitary construction help maintain product purity while allowing simultaneous processing.

Working principle
The stainless steel sanitary mixproof valve operates using a double-seat mechanism that separates two liquids. When one line is active, the lower seat opens to allow product flow, while the upper seat remains closed. A leak detection chamber between the seats vents any leakage safely. During cleaning, both seats lift slightly to allow CIP fluid to flow through. The valve's actuator controls the sequence precisely, ensuring that no cross-contamination occurs between product and cleaning lines in critical hygienic systems.

Product Description

Stainless steel sanitary valves are widely used in high-cleanliness industries and have the following significant feature:
1.Dual-seat separation ensures fluid integrity
The valve features two independent seats with a vented chamber in between, ensuring absolute non-mixing of product and CIP during operation.

2.Self-draining leak detection chamber
The middle cavity is pressure-balanced and self-draining, allowing quick leak identification and drainage without product contamination.

3.Balanced seat design for pressure stability
Seats are engineered to remain stable under reverse pressure, reducing seat lift risks and ensuring reliable performance in fluctuating systems.

4.Modular actuator with feedback options
The actuator integrates sensors for position and air control, supporting remote monitoring and integration into advanced automation systems.

5.Tool-free disassembly for maintenance
The valve body allows equick accss to internals without special tools, minimizing downtime during inspections or seal replacement.

6.CIP-optimized geometry with minimal dead zones
Internal flow paths and seat geometries are shaped for full cleanability, helping eliminate residues and ensure sanitary compliance.
