GR-2D series Downflow regeneration control valve is an improved version of the GR-2 with a modified lower valve design, achieving the widely used downflow regeneration control valve in the market. It avoids the strict requirements for resin breakage rate in upflow regeneration and the phenomenon of incomplete salt absorption or even backwashing. The salt tank water Refill is carried out in parallel with the B.wash process. Dry salt tank control valve.
