Six-Port, SilcoNert® 2000, Single Stage Cylinder Regulator for Reactive Analytical Applications

The CONCOA 420 Series regulator, treated with SilcoNert® 2000, is designed for primary pressure control of reactive or corrosive calibration mixtures and pure gases, providing an extremely inert wetted surface. The proprietary amorphous Silicon CVD coating delivers superior inertness and corrosion resistance compared to bare 316L stainless steel or other alloys. In its six-port configuration, the 420 Series is suitable for applications tolerating minor outlet pressure fluctuations or with gases stored below 500 PSIG (35 BAR). Maximum inlet pressure is at least 3000 PSIG (210 BAR), with optional configurations up to 4500 PSIG (310 BAR). Factory-installed options include single station manifold setup, purge, low-pressure alarm, or multiple inlets.

### Altecnic / Caleffi 312 Safety Valve - 312430 The Altecnic / Caleffi 312 Safety Valve - 312430 is an essential component for domestic hot water systems, designed to safeguard your hot water cylinder. This versatile valve is also crucial in heating systems, where it ensures the protection of boilers and other related components. Each valve is specifically selected based on the required set pressure; as pressure increases, the valve opens at the designated discharge pressure, efficiently releasing excess pressure to the atmosphere. This action prevents the system from reaching dangerously high levels that could jeopardise the boiler, hot water storage cylinder, and the safety of personnel in close proximity. #### Specifications: - **Size:** 1/2" x 1/2" - **Connections:** BSP Male Inlet x BSP Female Outlet - **Materials:** Brass - **Medium:** Air and Water - **Set Pressure:** 3 Barg - **Discharge Flow Rate:** 142.1 kg/hr - **Max Boiler Rating:** 82.5 kW - **Temperature Range:** +5 to +110 °C - **Product Code:** 312430 - **Notes:** WRAS approved, CE marked Ensure the safety and reliability of your heating systems with the Altecnic / Caleffi 312 Safety Valve - the perfect solution for maintaining optimal pressure levels and protecting your equipment.
