**FSLPDULP Ultra Low Pressure Rupture Discs: Reliable Protection for Low Pressure Systems** The FSLPDULP Ultra Low Pressure Rupture Discs offer a straightforward, dependable, and cost-effective solution for applications requiring protection at extremely low pressures, whether positive or negative. These rupture discs are primarily designed to safeguard processing and storage tanks, atmospheric vessels, and silos that operate under low design pressures and can only withstand minimal pressures and vacuums, thus preventing potential implosion or rupture. One particularly noteworthy application is their use in protecting biogas digesters. Constructed as flat composite discs, FSLPDULP rupture discs consist of four integral components: - A slotted, perforated metal section - A sealing membrane (commonly PTFE, but also available in various other metallic or non-metallic materials) - A protective section - A calibration ring with blades to enhance membrane rupture performance FSLPDULP rupture discs are designed to open without fragmentation, ensuring that product contamination is avoided. They can be tailored to accommodate a wide variety of non-standard specifications and applications, and can also be configured for dual pressure and vacuum protection to withstand both vacuum and counter-pressure environments. **Specifications:** - **Sizes:** Ranging from 2" (DN50) to 20" (DN500) - **Materials:** Options include Stainless Steel, Alloy 201, Alloy 400, Alloy 600, Alloy 625, Alloy C276, and Titanium.

**PREL107020 Potable Water Pressure Relief Valve** The PREL107020 Potable Water Pressure Relief Valve is specifically engineered to safeguard unvented cylinders from cold water over-pressurisation. Part of the Reliance Valves 107 Series, this pressure relief valve effectively discharges water from the system when a designated pressure threshold is exceeded, ensuring optimal safety and performance. The valves come pre-set and securely locked to a specific pressure; should the system experience over-pressurisation, the valve will lift from its seat, allowing excess water to flow to waste. This valve acts as the primary safety device within any unvented system. Available in pressure settings ranging from 3.5 to 6 bar, the PREL107020 also features various connection sizes, providing flexibility for installation. **Features and Benefits:** - **Diaphragm Design:** Enhanced resistance to scale build-up. - **Over-Pressurisation Protection:** Ensures your system operates safely, preventing potential damage. - **Multiple Connection Options:** Allows for versatile installation to suit different setups. - **Set Relief Pressure Range:** 3.5 - 6.0 bar, accommodating various system requirements. - **Cold Water Use Only:** Specifically designed for cold water systems, ensuring efficiency and safety. **Specifications:** - **Size:** 1/2" x 15mm - **Connections:** BSP Male Inlet x Compression Outlet - **Materials:** Hot Pressed DZR Brass - **Medium:** Water - **Set Pressure:** 3.5 Barg - **Temperature Rating:** Up to +110°C - **Product Code:** PREL107020 - **Notes:** WRAS approved Enhance the reliability and safety of your unvented water systems with the PREL107020 Potable Water Pressure Relief Valve – the essential component for effective pressure management.
