Stop Silent ASMK — Multicone Check Valve - Multicone Check Valve

Efficient production of coldness with minimal pressure loss. Producing coldness with river water is efficient and economical. Large quantities of river water must flow through the heat exchanger. Due to these large volumes, it is important to keep the system pressure loss to a minimum in order to maintain high efficiency. The layout of the system and the selection of its various components are an important element when low resistance is required. The Stop Silent multi-cone valve has been designed according to these flows in order to be best adapted to them. This blue valve body (see photo) can have dozens of Stop Silent check-valves (depending on the size), which can prevent water from flowing backwards in an optimal way.
