Luer diaphragm check valve

FAQ

1. What are the advantages of diaphragm check valves over traditional check valves?
A:

Simplified, lightweight design: Three-piece structure reduces installation complexity and system load.

Zero-leakage sealing: Silicone diaphragm ensures no backflow, ideal for high-purity applications (e.g., biopharmaceuticals).

Cost efficiency: High production yield and ultrasonic welding minimize maintenance and replacement costs.

3. What are the cracking pressure and pressure rating of diaphragm check valves?
A:

Ultra-low cracking pressure: 0.3 MPa for demanding fluid control.
(Keywords: low-pressure valve, high-pressure check valve specs)

4. Which industries benefit most from diaphragm check valves?
A:

Biopharmaceuticals: Sterile fluid transfer (GMP-compliant).

Food & Beverage: Hygienic production lines to prevent cross-contamination.

Chemical/Water Treatment: Corrosion-resistant design extends equipment life.
(Keywords: biopharma valves, food-grade check valve, chemical fluid control)

5. How to maintain diaphragm check valves for optimal performance?
A:

Regular diaphragm inspection: Check silicone diaphragms for wear every 6 months.

Avoid overpressure: Ensure system pressure ≤ rated maximum back pressure.

Cleaning tips: Use compatible solvents; avoid scratching sealing surfaces.

6. Why is ultrasonic welding critical for valve reliability?
A:

Seamless bonding: Eliminates leakage risks from adhesives or bolts.

Enhanced strength: 50% stronger joints withstand frequent pressure fluctuations.

Consistency: Automated process ensures batch-to-batch uniformity.
