E..-S
Spraywater control valve
Designed as a Z-body type valve, the E..-S’s anti-cavitation trim design forces the flow of spraywater through a three (optional four) stage cascade and an additional outlet cage. The multistage seat is a capsuled design, keeping the flow of spraywater away from the valve body. This successfully eliminates damage to the valve body caused by erosion and ensures a faultless operation over many years of operation.
