Sanitary Spring Check Valves

Product catalog summary

Product Overview
The document details the VRN-CC and VR-BIO sanitary check valves, designed to prevent reverse flow and cross-contamination in sanitary applications. These valves are suitable for both horizontal and vertical installations and are constructed from AISI 316L stainless steel.

Specifications

Materials: Valve bodies are made from AISI 316L stainless steel, with options for electro-polishing and different material grades.
Sizes: VRN valves range from 1/2” to 3”, while VR-BIO valves range from 1/2” to 6”.
Connections: Available in ASME-BPE clamp ends or weld ends, with ISO and DIN connections available on request.
Surface Finish: Internal surfaces have a finish of Ra < 0.5 microns, with optional electro-polishing.
Operating Conditions: Maximum product pressure is 10 bar, with a working temperature range of 0°C to 150°C. The standard opening pressure is 0.03 bar.

Design and Functionality
The valves are fully drainable and easy to dismantle and reassemble without tools. They feature a spring-loaded shutter guided by a disc sealed with O-rings, ensuring minimal bacteria traps and full traceability of wetted materials.

Compliance and Standards
The valves comply with the Pressure Equipment Directive PED 97/23/CE and the European Directive ATEX 94/9/CE. They meet FDA standards and are suitable for SIP/CIP sterilization and autoclaving.

Key Features

Elimination of mechanical return mechanisms for faster opening times.
High Cv value for efficient flow.
Full traceability of materials.

Installation and Maintenance
Care should be taken to protect internal seals during welding. It is recommended to disassemble the valves before welding to prevent damage.

Marking and Traceability
Each valve is permanently marked with the brand name, material grade, flow direction, and heat or lot number to ensure full traceability.

Ordering Information
To specify a valve, start with the product description and select additional options such as valve type, material, size, and process connection. Options include electro-polished finishes and compliance with ATEX standards.
