Shanghai Zhibang Valve Manufacture Co., Ltd. is a dedicated manufacturer specializing in high-performance flow control solutions. Since 2016, we have been supplying reliable valves to global markets, including North America, Europe, and Southeast Asia. Our Low Pressure Drop Check Valve for Drinking Water Treatment is engineered to provide minimal resistance in water lines, reducing energy costs while ensuring backflow prevention. With factory-direct pricing and professional technical support, we help you achieve optimal system efficiency and safety.
This check valve is designed specifically for drinking water applications, using materials that comply with sanitary standards. Its low-pressure-drop construction significantly reduces head loss compared to conventional swing or lift check valves, making it ideal for high-flow, low-pressure systems. Each valve undergoes rigorous testing to ensure leak-free performance and long service life.
Key Features & Technical Benefits
- Minimal Pressure Drop: The optimized spring-loaded disc design creates a streamlined flow path, reducing pressure loss by up to 30% compared to traditional check valves. This translates to lower pump energy consumption and reduced operating costs.
- Drinking Water Safe Materials: Available in stainless steel, brass, and ductile iron with NSF-approved EPDM or NBR seals. All materials are lead-free and suitable for potable water systems.
- Reliable Backflow Prevention: The spring-assisted closure mechanism ensures rapid response to reverse flow, preventing water hammer and contamination of the drinking water supply.
- Versatile Installation: Offered in flanged, threaded, and wafer connection types to fit existing piping systems. Compact design allows installation in tight spaces, both horizontally and vertically.
- Durable Construction: Body and disc are precision-cast and coated with anti-corrosion paint (for iron models) or polished to sanitary finish (for stainless steel). Tested to EN 12266 or API 598 standards.
- Low Maintenance: Simple design with few moving parts reduces the need for frequent servicing. The spring is made from stainless steel to resist fatigue and corrosion.
- Wide Size Range: Available from DN40 to DN300 (1.5" to 12"), with pressure ratings PN10/PN16 or Class 150. Custom sizes and special materials can be provided upon request.

Frequently Asked Questions (FAQ)
-
What is the typical pressure drop across this valve?
The pressure drop is very low, typically less than 0.1 bar at flow velocities up to 3 m/s for water. Exact values depend on size and flow rate; we provide performance curves on request. -
Are the materials safe for drinking water?
Yes. All elastomers (EPDM/NBR) are NSF/ANSI 61 compliant for potable water. Metal parts are lead-free. We can provide material certificates if needed. -
Can this valve be installed vertically?
Yes, the spring-loaded design allows installation in any orientation, including vertical pipelines, without affecting performance. -
What is the recommended maintenance interval?
Under normal drinking water conditions, the valve requires little to no maintenance. We recommend a visual inspection every 2 years or after 500,000 cycles. -
Is this valve suitable for hot water (up to 80°C)?
Yes, with EPDM seals it can handle continuous temperatures up to 80°C. For higher temperatures, optional Viton seals are available. -
What warranty do you offer?
We provide a standard 12-month warranty against manufacturing defects. Extended warranty options are available for bulk orders. -
Can I get a sample before bulk order?
Absolutely. We offer sample orders with a small quantity. Samples are shipped with full technical support. -
Do you have certificates for the valve?
Our manufacturing facility is ISO 9001:2015 certified. Specific product certificates (e.g., WRAS, NSF) can be arranged upon request for certain markets.
