Valves for industrial gases

Product catalog summary
Product Range Overview
The document provides a detailed overview of industrial cylinder valves, including standard valves, RPV valves, bundle and filling station valves, integrated valves, refrigerant valves, and accessories. Each type is categorized by gas type, working pressure, material, safety features, and standard diameter.
Introduction
The introduction outlines the applications of cylinder valves, focusing on bottle and bundle valves, and highlights technologies like O-ring sealing and flow coefficients Kv and Cv. It specifies the temperature range (-25° to +65°C) and valve lifetime (2000 cycles as per ISO 10297).
Technology Overview
The document describes technologies used in valve design, including standard cylinder valves, VIPR, and RPV, emphasizing safety and efficiency, such as RPV's contamination prevention and residual pressure maintenance.
RPV In-Line & Off-Line
Details on RPV technology include maintaining residual pressure, preventing contamination, and allowing direct top filling. The new RPV generation combines design and performance with features like flow-optimized design.
Valve Inlet and Filling Port
The valve inlet includes an anti-dust tube and an excess flow device for safety. The filling port is approved for 300 bar with high leak integrity and ignition resistance.
Pressure Gauge and Shut-Off Valve
The pressure gauge is designed according to EN ISO 10524-3 standards for safety and reliability. The shut-off valve is designed for high endurance and low torque operation.
Integrated Valves
Integrated valves feature a regulator safety relief device and a piston-type regulator for improved safety and reliability. The residual pressure valve protects against external contamination.
How to Select Valves
Guidance on selecting valves based on body materials, with brass being common for cost-effectiveness and strength. Consultation with material engineers is recommended for detailed guidance.
Working and Outlet Pressure
Models are designed for specific working pressures (200 to 450 bar). For low-pressure applications, the Indutec VIPR range is recommended. Customers should specify required pressures when ordering.
Inlet and Outlet Connections
Specific connections are required for each gas type, ensuring compatibility with upstream devices like pressure regulators and hoses.
Gas Compatibility
Ensuring valve body material compatibility with the gas type is crucial.
Technical Parameters for Valve Selection
Key parameters include product type, material type, gas type, sealing technology, handwheel type, working pressure, and connection standards.
Product Specifications and Features
Specifications for various valve models include CO2 and CO2 Mix Valves, Oxygen Valves, and RPV Valves, detailing working pressure, gas type, seat orifice size, helium leak rate, material specifications, and safety features.
Options and Customization
Valves can be customized with options like key operation, colored handwheels, chrome plating, and customer-specific logos. Safety features like burst discs and filters are available on request.
Conclusion
The document serves as a comprehensive guide for selecting and configuring valves to meet specific application requirements, ensuring safety and compatibility with various gases and standards.
Specifications
Working pressure ranges from 200 bar to 300 bar. Gas types include O2, N2O, inert gases, and mixtures. Seat orifice sizes vary, with helium leak rates at 10-3 mbarl/sec. Materials include aluminium, PA 6.6, EPDM, and brass. Temperature range is -20°C to +65°C. Safety features include burst discs and RPV.
Key Features

TECHNOLOGY OVERVIEW RPV IN LINE & OFF LINE WHY RPV? Under the RPV Expression is gathered a cassette unifying the following 2 qualities: - Residual pressure function - Non-return function RPV is used due to a physical necessity and not a technical one. When gas is withdrawn, once the bottle is empty, the bottle is disconnected by the user (client) and then it appears a risk of: - Dust - Corrosion - Inflammation of particles going outside Therefore it is safer to use an RPV valve. GENERAL FUNCTION The RPV is used to: - Keep a residual pressure in the cylinder Ensure, that at the end of gas extraction,...
