Stainless Steel Expansion Vessel for Potable Water Applications

The Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels are expertly designed to accommodate the increased load within water systems as water is heated and expands. These expansion vessels play a crucial role in maintaining safe operating levels, preventing excessive pressure build-up in both sealed heating and cold water systems. Each vessel features a replaceable membrane that safeguards against corrosion and contamination, ensuring that the water remains safe for human consumption. The inclusion of a replaceable membrane also facilitates easy servicing of the vessel without requiring removal, allowing for quick maintenance in situ.

Features and Benefits:

• Stainless Steel Bolted Flange: Resists corrosion for enhanced durability.
• Extra Wide Membrane Opening: Reduces noise caused by restricted flow for a quieter operation.
• Internal Membrane Protection: Ensures no contact between water and the steel shell, preventing internal corrosion.
• Comprehensive Size Range: Available in sizes from 2 to 5000 litres, catering to all applications.
• Easy Servicing: All models are supplied with a replaceable membrane for convenient maintenance without removal.
• Pre-Charge Valve: Allows for simple air pressure adjustments.
• Suitable for Hot and Cold Water: Designed specifically for these applications.

A marine fire-fighting valve is a specialised component installed on board ships as part of the fire main system, which provides seawater to combat fires across the vessel. These valves play a crucial role in controlling, directing, and isolating the water flow to fire hydrants, hoses, monitors, or sprinklers, ensuring the safety and effectiveness of fire-fighting efforts.

Purpose of a Marine Fire-Fighting Valve

• Deliver seawater from the fire pump to designated fire zones.
• Control or isolate sections of the fire main during emergencies.
• Interface with equipment such as fire hoses, foam systems, and water spray nozzles.

We offer a range of fire valves from leading manufacturers. Please get in touch with us to discuss your requirements.

The Rhodes 904 Sight Glass with Flap and Scale Plate is a flow indicator incorporating a pivoted internal flap, which, by its position in relation to a graduated scale-plate, indicates any changes in the rate of flow of a liquid in a pipeline, from a trickle to full flow conditions. 

The internal stainless steel flap is electropolished to improve viewing in murky liquids. The indicators are suitable for both horizontal and vertical upward flows. A variety of materials are available as standard. Rhodes Sight Glasses are fully UK manufactured with castings from the UK, unlike many of the competitors using components from the far east.
