D551 UHP CYLINDER VALVE WITH INTEGRATED PRESSURE REGULATOR

The Rotarex D551 Ducal is the first of it's kind Stainless Steel gas valve with integrated pressure regulator. The all in one design of the VIPR (valves with integrated pressure regulator) offers safer and easier calibration operations. The D551 series is designed for a wide range of specialty and corrosive gases, used to calibrate analysers.

Rotarex Puretec manufactures and provides ultra high purity cylinder valves for technical & inert gases, reactive gases, corrosive gases and toxic gases. The Puretec division carries out production in their ISO4 certified cleanroom with 100% helium leak testing on all of the products. Each valve undergoes strict quality control procedures including more than 14 visual, tactile or microscope controls on each valve, microscope toroid controls before and after the valve mounting, and internal/external tightness tests registered into the traceability system.

Key Features:

• Easy, ready to use all in one system.
• All surfaces in gas contact are oxygen clean and mainly metallic to minimize the gas contamination.
• Very constant flow from 200 to 7 bar in cylinder.
• Materials can also be used with corrosive mixtures.
• Equipped with manometers in stainless steel and downstream safety valve.

Valve Specifications:

• Connections: 25E - ISO 11363 3/4" NGT CGA-V1.
• Inlet Working Pressure: 200 BAR.
• Outlet Working Pressure: 1 to 4 BAR.
• Flow Rate: 1 L/min at 3 BAR, Max. Flow Rate 10 L/min at 4 BAR.
• Temperature Range: -20°C to +60°C.

• O-Ring: EPDM or FPM depending on application.
• Internal Components: Stainless Steel.
• Leak Rates: 1.10-7 mBAR L/sec.
• Property Level: Cleaned for Oxygen Service.
• Filling Tool Connection: To be defined according to gas types.

All-In-One Design:

• Pre-engineered complete solution to optimize your calibrated gas supply.
• Fully protected & integrated solution with ergonomic and aesthetic design.
• Superior productivity and better sealing due to reduction of potential leak points.

Easier and Safer:

• Easy handling and better protection thanks to plastic guard.
• Compact and light weight design ideal for mobile applications key features.
• High outlet flow stability and performance thanks to diaphragm technology.
• Premium material and components ensure quality of gas mixtures to preserve required properties for calibration application.

Higher Productivity:

• One complete system instead of many individual components.
• Save time and be much more effective with built-in solution.
