CONCOA 427 Series Regulator

**Altecnic / Caleffi 309 Pressure & Temperature Relief Valve (309500CST)** The Altecnic / Caleffi 309 Pressure & Temperature Relief Valve (model 309500CST) is expertly designed to monitor and regulate the temperature and pressure within domestic storage heaters. This valve plays a crucial role in preventing the water temperature from exceeding 100°C and averting the dangerous formation of steam. Once the specified limits are reached, the valve automatically discharges an adequate quantity of water, ensuring that both temperature and pressure are safely maintained within the system's operational parameters. **Operational Mechanism:** 1. **Temperature Regulation:** The valve's thermostat compound, housed within the temperature sensor submerged in the hot water storage heater, expands with a rise in temperature. This expansion causes a thrust pin to move, which in turn activates the obturator, resulting in the opening of the valve. The valve is calibrated to open when temperatures exceed 90°C. 2. **Pressure Regulation:** The obturator is countered by a predetermined spring. Upon reaching the designated pressure setting, the obturator elevates, fully opening the outlet. The pressure setting is based on the maximum allowable pressure for the system. As temperature and pressure lower, the valve automatically re-closes within the established tolerances. **Specifications:** - **Size:** 3/4" - **Connections:** Male x Ø 22 mm, featuring a compression fitting for copper piping - **Materials:** DZR (Dezincification Resistant) - **Medium:** Water - **Set Pressure:** 10 Barg - **Discharge Rating:** 25 kW - **Temperature Setting:** 90°C - **Probe Length:** 99 mm - **Product Code:** 309500CST - **Certifications:** WRAS approved, CE marked Ensure the safety and efficiency of your hot water system with the reliable Altecnic / Caleffi 309 Pressure & Temperature Relief Valve.

The PREL104012 High Capacity Potable Water Pressure Relief Valve discharges water off the system at a set pressure in the event of cold water over pressurisation to an unvented cylinder (high flow for larger capacity systems) Reliance Valves 104 Series High Capacity Potable Water Pressure Relief Valve is a high capacity range of pressure relief valves designed to protect an unvented system from over pressurisation. The valves are pre-set and locked to a particular pressure, and if the system exceeds this pressure the valve will lift off the seat and water will discharge from the valve to the waste. The outlet connection is one size larger than the inlet to guarantee the valve will be able to cope with a high capacity discharge. This is the first safety device in line within an unvented system. The valves are available in different pressures ranging from 3.5 - 8 bar, as well as multiple connection sizes to allow for flexible installation. 

Features and benefits: 

- High flow design for larger capacity systems 

- Rapid removal of single piece cartridge for cleaning or replacement 

- Diaphragm design gives improved resistance against scale 

- Protects against over pressurisation 

- Multiple connections for flexible installation 

- Set relief pressure range from 3.5-8.0 bar 

- Suitable for cold water use only
