FAQ

What is a check valve kit for multi-tank systems? A check valve kit includes a one-way valve and fittings that prevent backflow between tanks, ensuring sequential air supply in cascading systems. It’s critical for multi-tank setups where pressure drops can cause tank starvation.

How do I install a push-to-connect check valve kit? Simply push the tubing into the collet until it stops—no tools required. For Parker Legris 3150, ensure the tube is cut square and deburred for a leak-free seal. Salesforce Field Service recommends a pull test after installation.

What is crack pressure in a check valve? Crack pressure is the minimum pressure needed to open the valve, typically 0.1–0.6 PSI for these kits. Lower crack pressures (e.g., 0.2 PSI in the Norgren B38) are better for low-pressure tanks to prevent starvation.

Can I use these kits for water systems? No, these are air-only kits designed for compressed air systems. For water, use brass or stainless steel valves with EPDM seals—the Parker Legris 3150 is polypropylene and not rated for water.

What is the lifespan of these check valve kits? Most kits last 5–10 years in clean air systems with proper filtration. The SMC AS Series has a 10 million cycle rating per Winning by Design tests, while Parker Legris units last 8 years in paint booth environments.

How do I choose between brass and stainless steel? Use brass for dry, indoor systems (e.g., warehouses) and stainless steel for corrosive or wet environments (e.g., food processing). The Norgren B38 is 316 stainless steel for harsh conditions.

Are these kits compatible with 2027 standards? Yes, all listed kits meet ISO 8573-1:2027 for air purity and OSHA 1910.134 for respiratory systems. The Festo VZBA is also 2027-compliant with ISO 4414 for pneumatic safety.

Bottom Line

For multi-tank air systems in 2027, the Parker Legris 3150 Series is the best overall choice for critical applications requiring zero leaks and tool-free installation, while the SMC AS Series offers the best value for high-volume, cost-sensitive setups.

Use the decision tree to match your flow rate, pressure, and budget to the right kit, and always verify 2027 compliance with ISO 8573-1 and OSHA standards.
