Niezgodka Type 80 SMS Sustaining Valve (Low Pressures)

Introducing the FSSCRRA Reverse Acting Rupture Discs – advanced compression or reverse discs featuring micro-scored calibrated sections that open in the form of petals. These discs are designed with 4, 6, or more radial scores, allowing for optimal opening and significantly reducing the risk of petal detachment. The FSSCRRA rupture discs are ideally suited for both high and low bursting pressures and can be safely utilised with gases and liquids (when a special gas cushion is present), even under cycling and pulsating conditions, without compromising safety margins. Reacting to excessive pressure within mere milliseconds, FSSCRRA rupture discs operate without fragmentation, making them particularly effective for the protection of safety valves. These rupture discs boast an impressive operating to bursting pressure ratio of up to 95% and demonstrate excellent corrosion resistance. This resistance can be further enhanced with a PTFE lining. Notably, FSSCRRA discs can operate under absolute vacuum conditions without requiring additional supports.

The Valfonta Model 280 Steam Reheater is designed to elevate the temperature of liquids flowing through a central pipe. This innovative device injects steam through the upper flange, which circulates through strategically placed small holes in the nozzle. As a result, steam jets are generated, propelling the fluid into a low-pressure area and creating turbulence. This effective mixing of liquid and steam leads to a significant increase in temperature, accompanied by a rise in pressure. The Valfonta Model 280 is renowned for its exceptional reliability, as it operates without any moving parts.

**Rhodes 923 Sight Glass with Integral Spout: Expertly Designed for Enhanced Liquid Observation** The Rhodes 923 Sight Glass with an integral spout is engineered to create a jetting action that promotes turbulent flow, significantly enhancing the visibility of clear liquids. Its expansive viewing area enables you to monitor the flow, colour, and overall condition of the liquid, ensuring a reliable assessment of product quality and consistency. These sight glasses are versatile and can be installed in both vertical and horizontal orientations. The built-in spout feature allows them to function as drip indicators, effectively alerting you to valve leaks, distillation issues, or similar conditions. Available in a variety of materials as standard, Rhodes Sight Glasses are proudly manufactured in the UK, utilising locally sourced castings, unlike many competitors who rely on components from overseas. **Key Specifications:** - **Sizes:** Ranging from 1/2" to 2" - **Connections:** Available in Butt Weld, Screwed, and Flanged options (most types are feasible) - **Materials:** Constructed with a Carbon Steel body, Mild Steel covers, and Graphite gaskets - **Maximum System Pressure:** Capable of handling Full Vacuum conditions up to 25 Barg - **Temperature Range:** Effective in temperatures from -30°C to 250°C - **Compliance:** Fully compliant with the Pressure Equipment Directive (PED) and entirely manufactured in the UK Upgrade your liquid monitoring solutions with the Rhodes 923 Sight Glass, designed for superior performance and durability.
