A "dual-pressure" check valve is standard on all SUPERIOR Gas Chlorinators, Sulfonators and Ammoniators. Proven high back-pressure unitized check valve design protects against sudden surges up to 300PSIG while a spring-loaded diaphragm check provides positive shut-off even when there is no back-pressure to force the seat closed.
