Hygenic Tri-Clamp Liquid Turbine Flow Meter

The CONCOA 332 Series is a five-port, stainless steel, dual-stage cylinder regulator designed for primary pressure control of high-purity inert gases (up to grade 5.5), including mildly reactive gases—but not toxic or highly corrosive gases. Its two-stage design minimizes pressure fluctuations from cylinder depletion, providing stable delivery pressure for critical applications. Factory-configurable options make it ideal for university labs, research facilities, and pharmaceutical manufacturing.

The Altecnic / Caleffi 309 Pressure & Temperature Relief Valve - 309473CST is designed to effectively control and limit the temperature and pressure of hot water in domestic storage heaters. This essential safety device prevents water temperatures from exceeding 100°C, thereby eliminating the risk of steam formation. When the system reaches predetermined pressure or temperature thresholds, the valve discharges a sufficient amount of water into the atmosphere, ensuring that both temperature and pressure are maintained within safe operating limits. The valve's mechanism operates as follows: - **Temperature Control:** As the temperature in the storage heater rises, the thermostat compound within the temperature sensor, which is submerged in hot water, expands. This expansion causes a thrust pin to move, actuating the obturator and opening the valve. The valve is set to activate at temperatures exceeding 90°C. - **Pressure Control:** When pressure limits are reached, the obturator, which is opposed by a set spring, lifts and fully opens the outlet. The pressure setting is specifically configured according to the maximum allowable pressure within the system. As temperature and pressure subside, the valve automatically re-closes within designated tolerances.

The Brownall Air Eliminator is essential for any heating system to effectively eliminate air pockets. This reliable valve can withstand a maximum pressure of 10 bar and operates efficiently at temperatures of up to 93°C. Formerly marketed as the Charles Winn Automatic Air Eliminator, more than 200,000 units have been sold across the UK over the past 25 years. Many of these valves remain in service today, demonstrating their exceptional durability and ability to provide long-term, trouble-free operation.
