VALPRES Split Body Ball Valves - Direct Mount PN16 / PN40 / ANSI 150

The Rhodes 400 sight flow indicator is designed for optimal performance, featuring either a high sensitivity spinner or a ball that operates from just 0.7 litres per minute (when using water). Constructed with nitrile seals, a nylon spinner, or a PTFE ball, this indicator offers exceptional chemical resistance. The stainless steel version further enhances durability by including borosilicate glass as a standard feature.

These compact sight flow indicators are widely utilised in plant protection applications, effectively displaying the flow of coolant or lubrication to pumps, compressors, and engines. One of the significant advantages of the Series 400 is its versatility; it can be installed in any orientation, with the exception of the ball type, which requires horizontal positioning.

Sizes: 1/4", 3/8", 1/2", 3/4", 1"
Connections: Female BSPT Inlet x Female BSPT Outlet
Materials: Gunmetal or Stainless Steel
Maximum System Pressure: 7 Barg (Gunmetal) / 16 Barg (Stainless Steel)
Temperature Range: Up to 100°C

The Valfonta S3 Straight Pattern Pressure Relief Valve is designed to effectively regulate upstream pressure, maintaining it at a predetermined set point. When the upstream pressure exceeds this set point, the valve opens proportionally, allowing for the controlled release of excess pressure.

**Product Description: Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves** The Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves are expertly designed compact units that safeguard against the risks of over-pressurisation in unvented hot water systems. Such over-pressurisation can occur if temperature or pressure controls fail. These valves are specifically engineered to be installed at the upper section of a hot water cylinder, where the highest temperatures in the system are typically found. When the temperature exceeds 95°C, the wax mixture within the temperature probe element expands, lifting the valve off its seat and allowing water to escape, thereby relieving pressure within the cylinder. Additionally, the valve remains closed in the event of rising water pressure without a corresponding temperature increase. It will only open once the pre-set pressure threshold of the relief mechanism is reached, effectively releasing any excess pressure. Certain models come with a PTFE coating on the MBSP inlet thread, which streamlines the installation process, saving you valuable time. **Key Features and Benefits:** - Provides protection against temperatures exceeding 95°C - Prevents over-pressurisation in hot water systems - Twist-top cartridge design allows for easy servicing - Available in a range of pressure settings and probe lengths - Some models include a PTFE coating for enhanced installation efficiency **Specification:** - **Size:** 15mm x 15mm - **Connections:** Compression Inlet x Compression Outlet - **Materials:** Brass - **Medium:** Hot water only - **Set Pressure (Set & Locked):** 7 Barg - **Temperature Relief:** +90 to 95°C - **Discharge Capacity:** 10kW - **Probe Length:** 200mm - **Product Code:** PTEM550953 - **Notes:** Long probe, WRAS approved Enhance the safety and efficiency of your hot water system with the RWC TPR15 Pressure and Temperature Relief Valves – the trusted choice for reliable temperature and pressure control.
