Cla-Val 90G-21 (globe) and 90A-21 (angle) Pressure Reducing Valves automatically reduce higher inlet pressure to a steady lower outlet pressure regardless of changing flow rate and/or varying inlet pressure. The valves pilot control system is very sensitive to slight downstream pressure fluctuations, and will automatically open or close to maintain the desired pressure setting.
The DVN/DVNI fans are intended to use for extract air with vertical discharge. DVN/DVNI are the smart choice when requirements are higher than average, in applications such as extraction from kitchens, process air systems and industrial ovens. They are suitable for continuous air flow temperatures up to 120°C.
