VNE Spring Check Valves: Dependable Protection Against Backflow
Introduction to VNE Spring Check Valves
VNE is pleased to offer a premier selection of Spring Check Valves, designed to provide reliable backflow prevention in a wide array of sanitary and industrial applications. These valves are engineered to ensure fluid does not flow back into the system, creating a positive shutoff that is critical in maintaining the integrity and efficiency of your operations.
Robust Design and Specifications
Our Spring Check Valves are available in sizes ranging from 0.5" to 4", accommodating a diverse range of system requirements. They are typically installed in a vertical position to optimize backflow prevention and are crafted from T316L stainless steel, ensuring durability and resistance against corrosion. The finish on these valves is polished to 32 Ra μ-in. ID/OD, which not only contributes to their robust structure but also supports sanitary standards by providing an easy-to-clean surface that reduces contamination risks.
Optimal Sealing and Performance
The valves feature a one-piece stem with an O-ring construction, which simplifies seal replacement and enhances the valve’s ability to shut off fluid flow securely. EPDM and Viton® are standard options for the seats and seals, offering excellent chemical resistance and suitability for various temperatures and environments. For specialized needs, options such as metal detectable, silicone, and Kalrez® seals are also available, ensuring that we can cater to the most specific and demanding applications.
Pressure and Temperature Compatibility
These spring check valves are designed to handle maximum product pressures up to 145 psi and are rated for temperatures ranging from 0° to 200°F. This range allows them to perform reliably under a variety of operational conditions, making them suitable for a vast spectrum of media and applications.
Ease of Maintenance and Traceability
VNE Spring Check Valves conform to the 3A Sanitary Standards for vacuum breakers and check valves, ensuring compliance with stringent industry regulations. Each valve is marked with heat numbers for full identification and traceability, with Material Test Reports (MTR’s) available upon request to verify compliance and quality. The design also facilitates easy maintenance and replacement, with clear part numbering for ordering replacement parts or requesting specific O-Ring materials.
