Reliance RWC 104 Series Pressure Relief Valve 1.1/4

Reliance RWC 104 Series Pressure Relief Valve 1.1/4" x 1.1/2" F x F 8 Bar - PREL104013

**PREL104013 High Capacity Potable Water Pressure Relief Valve** The PREL104013 High Capacity Potable Water Pressure Relief Valve is engineered to release water from the system at a predetermined pressure, effectively managing cold water over-pressurisation in unvented cylinders. Designed for high flow rates, this valve is particularly suitable for larger capacity systems. The Reliance Valves 104 Series provides reliable protection for unvented systems against over-pressurisation. Each valve is pre-set and securely locked to a specific pressure—if the system pressure surpasses this limit, the valve will lift from the seat, allowing water to discharge safely to waste. The valve's outlet connection is sized one inch larger than the inlet, ensuring optimal flow capacity during high discharge demands. As the primary safety device in an unvented system, these valves offer peace of mind and robust performance. Available in various pressure settings from 3.5 to 8 bar, and with multiple connection sizes for ease of installation, the PREL104013 is a versatile solution for any plumbing system. **Features and Benefits:** - **High Flow Design**: Ideal for larger capacity systems. - **Easy Maintenance**: Quick removal of the single-piece cartridge for cleaning or replacement. - **Durable Diaphragm**: Enhanced resistance against scale build-up ensures longevity. - **Over-Pressure Protection**: Guards against potentially damaging over-pressurisation. - **Flexible Installation**: Multiple connection options cater to diverse installation requirements. - **Adjustable Pressure Range**: Set relief pressure from 3.5 to 8.0 bar. - **Cold Water Usage**: Specifically designed for use with cold water. **Specifications:** - **Size**: 1.1/4" x 1.1/2" - **Connections**: BSP Female Inlet x BSP Female Outlet - **Materials**: Hot pressed DZR Brass - **Medium**: Cold Water - **Set Pressure**: 8 Barg - **Temperature Rating**: +140 degrees Celsius - **Product Code**: PREL104013 Ensure your unvented system is protected with the reliable performance of the PREL104013 High Capacity Potable Water Pressure Relief Valve. Perfect for both residential and commercial applications, this valve is essential for maintaining a safe and efficient plumbing system.

Auld Double Control Reducing Valve

Auld Double Control Reducing Valve

Auld Valves Ltd has ceased trading. However, please reach out to us, as we may have alternative options available in our product range.

The Auld Double Control Reducing Valve is ideal for applications requiring substantial pressure reductions, provided that the inlet pressure does not exceed 51 barG. This valve features a self-contained balance pipe, ensuring optimal performance with a closing pressure of +7% relative to the reduced pressure. Its balanced design remains unaffected by fluctuations in inlet pressure and responds instantly to changes in demand. The valve offers impressive reduced pressure accuracy of ±5% across a flow range from full flow down to 10% (with a turndown ratio of 10 to 1). Furthermore, its soft valve faces are well-suited for dead end conditions, and the single seat design facilitates precise control at low flow rates.

Storm Valve

Storm Valve

A marine storm valve is a specialised check valve designed for installation in a ship’s sewage or drainage systems. Its primary function is to prevent seawater from backflowing into the vessel, especially in heavy seas or when the ship is heeled. By serving as a barrier against flooding and contamination through overboard discharge pipes, marine storm valves play a crucial role in maritime safety.

Purpose of a Marine Storm Valve

  • Prevents seawater ingress through overboard discharge openings.
  • Facilitates the one-way flow of wastewater, bilge, or greywater out of the ship.
  • Vital for sewage, greywater, and drainage systems located below the waterline.

We supply marine storm valves from a range of leading manufacturers. Please contact us to discuss your specific requirements.
