Resideo DDS76 Differential Pressure Switch

Six-Port, SilcoNert® 2000, Single Stage Cylinder Regulator for Reactive Analytical Applications

The CONCOA 420 Series regulator, treated with SilcoNert® 2000, is designed for primary pressure control of reactive or corrosive calibration mixtures and pure gases, providing an extremely inert wetted surface. The proprietary amorphous Silicon CVD coating delivers superior inertness and corrosion resistance compared to bare 316L stainless steel or other alloys. In its six-port configuration, the 420 Series is suitable for applications tolerating minor outlet pressure fluctuations or with gases stored below 500 PSIG (35 BAR). Maximum inlet pressure is at least 3000 PSIG (210 BAR), with optional configurations up to 4500 PSIG (310 BAR). Factory-installed options include single station manifold setup, purge, low-pressure alarm, or multiple inlets.

Introducing the Rhodes 400B Sight Glass with Ball Indicator, an affordable and accessible sight flow indicator designed for optimal performance, featuring a high sensitivity ball that operates from just 0.7 l/m (water). Constructed with nitrile seals and a PTFE ball, this indicator boasts exceptional chemical resistance, further enhanced in the stainless steel variant by the inclusion of borosilicate glass as standard.

This compact sight flow indicator is widely utilised in plant protection applications, effectively displaying coolant or lubrication flow to pumps, compressors, and engines. The 'ball type' design requires horizontal mounting for accurate functionality. Unlike many competitors that source components from the Far East, Rhodes Sight Glasses are fully manufactured in the UK, utilising locally-sourced castings.

Available Sizes: 1/4", 3/8", 1/2", 3/4", 1"

Connection Type: Female BSPT Inlet x Female BSPT Outlet

Materials: Gunmetal or Stainless Steel Body, Nitrile O Ring

Maximum System Pressure: 7 Barg (Gunmetal) / 16 Barg (Stainless Steel)

Temperature Resistance: Up to 100°C Max

Additional Information: Fully compliant with the Pressure Equipment Directive (PED). Proudly manufactured in the UK.

Optimize your system's efficiency with the Rhodes 400B Sight Glass, a robust and reliable choice for flow indication in various industrial applications.

The AURA EX1 is a versatile regulator designed for precise primary pressure control of gases or liquids, accommodating inlet pressures of up to 6000 psig. This regulator is particularly well-suited for applications where minor outlet pressure fluctuations from varying inlet pressures can be tolerated. At the heart of the EX1 lies AURA’s innovative encapsulated seat design, which consolidates multiple internal moving components into a single unit. This streamlined design simplifies maintenance, reduces potential failure points, and significantly enhances reliability. The encapsulated seat is safeguarded by a 10-micron, 360° filter, providing superior impurity capture compared to traditional pressed-in disks. Unlike standard designs that filter solely through the pipeline port, the EX1 protects against harmful particles from all inlet ports, ensuring optimal performance. With an array of seat materials and orifice sizes available, the EX1 is engineered to deliver optimal performance across a variety of applications. AURA's precision machining process achieves surface finishes between 4–25 Ra, effectively minimising corrosion risks. Additionally, the regulator's low internal volume reduces the amount of gas required during purging, enhancing operational efficiency. Every EX1 unit is meticulously assembled within a Class 100 cleanroom as a complete system, which includes gauges, fittings, and valves, and is fully prepared for oxygen service. Each unit undergoes 100% helium leak testing and multiple flow and function checks, ensuring maximum purity, durability, and leak integrity. For applications that encounter harsh chemicals, the EX1 can also be outfitted with Dursan® LS coating technology, renowned for its exceptional corrosion resistance, often outperforming exotic metals in highly acidic or caustic environments. For secondary pressure control or less demanding applications, the EX1P presents a cost-effective alternative. This variant utilises the same robust pressure regulation mechanism and wetted parts as the EX1 but features a chrome-plated brass bonnet and a polycarbonate knob. The EX1P is ideal for panel-building and point-of-use assemblies; however, it is not assembled in a Class 100 cleanroom like its counterpart. **Key Benefits:** - Comprehensive pressure control for gases and liquids up to 6000 psig - Innovative encapsulated seat design for enhanced reliability - 10-micron, 360° filter for superior impurity capture - Tailored options for various applications through different seat materials and orifice sizes - Low internal volume for efficient operation - Dursan® LS coating for added corrosion resistance in harsh environments - 100% helium leak tested for guaranteed purity and durability Explore the exceptional performance of the AURA EX1 today and discover the ideal solution for your pressure regulation needs.
