Medenus RS254 Gas Pressure Regulator & Shut Off Valve

The CONCOA 304 Series is a three-port, chrome-plated brass, single-stage point-of-use regulator designed for high-purity, non-corrosive, or liquefied gases (up to grade 5.5). It provides secondary or final-line pressure control, reducing delivery pressure in a single step. Its durable construction and high-purity compatibility make it a cost-effective solution for applications that can tolerate minor outlet pressure fluctuations as cylinder supply decreases. Maximum inlet pressure is 3000 PSIG (210 BAR) or higher, depending on configuration.

The Altecnic / Caleffi 312 Safety Valve - 312425 is an essential component for domestic hot water systems, designed to safeguard hot water cylinders and heating systems, including boilers and other critical components. This safety valve is chosen based on the specific set pressure required for your system. As pressure increases and reaches the predetermined discharge pressure, the valve opens, allowing excess pressure to escape to the atmosphere. This vital function prevents the internal pressure from escalating to levels that could pose a risk to the boiler, hot water storage cylinder, and the safety of personnel nearby.
