Sanitary Non Return Clamped Check Valve

DIYE VALVE Sanitary Non Return Clamped Check Valve is designed for high-purity, sterile, and zero-leakage scenarios. With "hygiene and safety" as its core, it eliminates the risk of media stagnation and cross-contamination in pipelines, making it an essential component of high-standard clean fluid delivery systems and suitable for various hygiene-sensitive industries.

Core Product Advantages:

1.Strict Compliance with Hygiene Standards

The Sanitary Non Return Clamped Check Valve strictly complies with GMP, FDA, and 3-A hygiene standards. Its integrated, seamless welded structure has no disassembly gaps, fundamentally preventing bacterial growth and cross-contamination, meeting the aseptic production requirements of industries such as pharmaceuticals and bioengineering.

2. Premium Materials

The Sanitary Non Return Clamped Check Valve uses SUS304/SUS316L medical-grade stainless steel forgings, rejecting inferior castings. The material has a dense, defect-free grain, eliminating the risk of fluid stagnation at the source. It boasts strong corrosion resistance and can stably contact various clean fluids for extended periods without contaminating the media.

3. Precision Machining

Core components are precision-machined using CNC. The coaxiality error of the flow channel, welded ends, and sealing seat is ≤0.02mm. Dimensions conform to ISO and DIN hygienic welding standards. The bevels are smooth and burr-free, ensuring a tight seal and preventing leakage or backflow.

Product Applications

The Sanitary Non Return Clamped Check Valve, with its stringent hygiene standards and stable performance, is widely used in various hygiene-sensitive industries, specifically:

1. Food and Beverage Industry: Used in beer and juice production lines to prevent material backflow and cross-contamination, ensuring product safety.

2. Dairy Industry: Suitable for conveying fresh milk, yogurt, etc., preventing contamination, preserving the product's nutritional value and taste, and meeting industry hygiene requirements.

FAQ

Q: What are the advantages of clamp check valves compared to welded check valves?

A: Clamp-type connections require no welding and allow easy installation, disassembly, routine maintenance, cleaning and parts replacement. They are ideal for production lines that need frequent disassembly.The connections comply with international standards such as ISO, DIN and SMS, offering strong interchangeability, combining cleanliness and practicality.

Q: Can welded check valves / clamp check valves be used for steam sterilization and strong acid / weak alkali media?

A: Yes.With EPDM gaskets, they can withstand SIP in-place steam sterilization.With 316L material + PTFE seals, they are suitable for weak acids, weak alkalis and high-temperature clean fluids.Special working conditions can be satisfied by proper selection.

Q: What are the mandatory technical requirements for installing clamp check valves or welded check valves?

A: Installation must follow the flow direction arrow marked on the valve body.They can be installed horizontally or vertically (medium flowing upward).Reverse installation is strictly prohibited.Pipeline impurities must be cleaned before installation to avoid scratching the sealing surface and causing seal failure.
