Product Description

Technical Specifications
Valve Type: Wafer check valve Structure: Double disc
Standard: AWWA C594 Workmanship: Investment casting
Sealing direction: Single-directional Sealing grade: Zero leakage
Temperature: -40°C < T < 800°C Operation: Self-starting
Core Characteristics
The clamp check valve is crafted from high-grade stainless steel. Its core advantages are focused on three vital dimensions: corrosion resistance, high adaptability, and extreme durability. These features significantly enhance valve reliability under complex industrial working conditions.
Stainless Steel Valve Characteristics
Key Advantages
1 Wide Temperature Adaptability
Stainless steel maintains stable mechanical properties between -40°C and 450°C. Depending on sealing choices (fluororubber or metal hard seals), it handles cryogenic media, high-temperature steam, and hot oil without the risk of brittle cracking seen in cast iron valves.
2 Lightweight & Compact Design
With a lower density than cast steel and a compact wafer-style structure, this valve reduces the load on pipeline flanges. It requires no additional reinforcement brackets, making it ideal for systems with limited space or strict weight requirements.
3 Low Maintenance Costs
The smooth inner walls prevent scaling and coking. Its anti-corrosion properties minimize jamming of internal components, ensuring long-term opening/closing reliability and reducing the frequency of costly shutdown maintenance.
Double Disc Valve Advantages
Packing & Logistics
Standard Export Wooden Case Packaging: Each valve is secured in reinforced wooden crates to ensure safe international transit and prevent mechanical damage.
Valve Export Packaging
Application Scenarios
Extensively used across chemical processing, petroleum refining, pharmaceutical manufacturing, food production, seawater desalination, water treatment, and HVAC systems. It is perfect for environments requiring high medium purity and strict corrosion resistance.

Frequently Asked Questions
Q: What is the temperature limit for this wafer check valve?
The valve is designed for an impressive range of -40°C to 800°C. For specific high-temp or cryogenic needs, the sealing seat material (e.g., metal hard seal or fluororubber) is customized accordingly.
Q: Does this valve comply with international standards?
Yes, this wafer check valve is manufactured in strict compliance with the AWWA C594 standard, ensuring high quality and dimensional precision for industrial use.
Q: What industries benefit most from the stainless steel construction?
It is ideal for chemical, pharmaceutical, and food industries where corrosion resistance and medium purity are critical. It is also widely used in seawater desalination and HVAC systems.
Q: Is the sealing performance reliable for backflow prevention?
Absolutely. The valve features a double disc structure and investment casting workmanship, achieving a "Zero Leakage" sealing grade for single-directional flow.
Q: How do you ensure the valve isn't damaged during shipping?
We use standard export wooden cases that provide robust protection against impact and moisture, ensuring the valve reaches the site in perfect operating condition.
