**PREL106003 Potable Water Pressure Relief Valve** The PREL106003 Potable Water Pressure Relief Valve is designed to safeguard unvented systems from over-pressurisation. In the event of excessive cold water pressure, this valve will discharge water from the system at a predetermined pressure, ensuring the safe operation of your unvented cylinder. Reliance Valves 102 Series Potable Water Pressure Relief Valves are pre-set and securely locked to a specific pressure. When the system pressure exceeds this limit, the valve lifts off its seat, allowing water to discharge safely to waste. This valve acts as the primary safety device within your unvented system. Manufactured with a robust single-piece cartridge, these pressure relief valves are available in various pressure settings and connection sizes, facilitating straightforward installation. **Features and Benefits:** - **Quick and Easy Cartridge Removal:** The single-piece cartridge can be rapidly removed for cleaning or replacement. - **Improved Scale Resistance:** The advanced diaphragm design enhances resistance to scale build-up, ensuring long-lasting performance. - **Over-Pressurisation Protection:** Safeguards your system against potential over-pressurisation issues. - **Flexible Installation Options:** Multiple connection sizes allow for versatile installation configurations. - **Wide Relief Pressure Range:** Set at 10 bar, suitable for various applications. - **Cold Water Use Only:** Specifically designed for cold water systems. **Specifications:** - **Size:** 1/2" x 1/2" - **Connections:** BSP Male Inlet x BSP Female Outlet - **Materials:** Hot pressed DZR Brass - **Medium:** Water - **Set Pressure:** 10 Barg - **Temperature Rating:** +140°C - **Product Code:** PREL106003 - **Certification:** WRAS approved Ensure the safety and reliability of your unvented water system with the PREL106003 Potable Water Pressure Relief Valve – your first line of defence against over-pressurisation. Perfect for installation in residential and commercial settings alike.

The CONCOA 414 Series five-port, bare brass barstock regulator provides dual-stage primary pressure control for ultra-high purity, non-corrosive, or liquefied gases. Two-stage regulation ensures stable delivery pressure despite cylinder depletion, making it ideal for applications requiring consistent flow. It can be installed directly on top-outlet cylinders or via a bracket with flexible hose. Features include metal-to-metal diaphragm seal, CAPSULE® seats with 360° filtration, pipe-away relief, helium leak-checked integrity, cleanroom assembly, captured vent bonnet, and front/rear panel mounting. Constructed from brass barstock body and bonnet, PTFE/PCTFE seats, 316L diaphragm, 10-micron sintered bronze filter, 2 in brass gauges, Cv 0.1, PTFE internal seals, 1/4 in FNPT ports. Max inlet pressure: 3000 PSIG (3500/4500 optional). Temperature range: -40°F to 140°F (-40°C to 60°C). Compliant with CGA G-4.1, ANSI/ASME B40.1, PED 2014/68/EU, CRN OH5216.5R2.

**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. Perfectly suited for domestic use, this valve meets strict industry standards while optimising your heating system's performance.
