Product Overview
Engineered with precision for the highest standards in purity industries like food processing, pharmaceuticals, and biotechnology, this sanitary stainless steel check valve is pivotal in preventing reverse fluid flow within pipeline systems, thereby assuring process stability and safety. Its intuitive quick-connect design, coupled with high-grade corrosion-resistant materials and meticulous precision polishing, ensures it meets the most rigorous standards for sterility, effortless cleaning, and resilience to high temperature and pressure.
Key Features
1. Material & Hygiene Certifications
- Constructed with SUS 304 or 316L stainless steel featuring a mirror-polished surface (Ra ≤0.6μm), this valve adheres to ISO, DIN, and 3-A sanitary standards, making it ideal for food and pharmaceutical-grade applications.
- Sealing materials include EPDM, silicone (SI), fluorocarbon (FPM), or PTFE gaskets, all designed for superior corrosion resistance and compatibility with high-temperature steam as well as CIP/SIP cleaning processes.
2. Quick-Install Design
- Offers versatile connection types such as Tri-clamp (Clamp), welded, or flanged connections ensuring rapid installation and ease of maintenance, perfectly suited for environments requiring frequent cleaning.
- Its compact structure is lightweight and space-efficient, featuring a smooth flow path that prevents media retention, adhering strictly to sanitary zero-dead-space standards.
3. Performance Specifications
- Standard pressure range is 1.0 MPa, with customizable options available for high-pressure models, extending up to 1.6-6.4 MPa.
- Temperature operational range spans from -10°C to +150°C, with short-term tolerance reaching up to +250°C, contingent on the sealing material used.
- Available in bore sizes from DN15 to DN100 (1/2"-4"), ensuring compatibility with a wide variety of pipeline systems.
4. Operating Principle
- The valve operates automatically, opening under forward flow and closing under reverse pressure or spring tension, effectively preventing any backflow.
Applications
- Food & Beverage: Perfect for dairy processing lines, beer filling systems, and juice transfer pipelines.
- Biopharmaceuticals: Ideal for purified water systems, fermentation tanks, and injection production equipment.
- Fine Chemicals: Designed for high-corrosion chemical fluid transfer systems.
Packaging & Warranty
- Each valve is meticulously packaged in vacuum-sealed dust-proof bags and cushioned with shock-proof wooden crates. Comes with comprehensive installation guides and certification documentation.
- Offers a warranty period between 12-18 months, with support for third-party inspections and custom designs like non-standard sizes or specific pressure requirements.
