    Ultra-Chemical-Resistant Threaded Check Valves

    The most chemical-resistant check valves in our offering, these have a PFA body to withstand methyl ethyl ketone, sodium hypochlorite, and other extremely harsh chemicals. They open to allow flow in one direction and close when flow stops or reverses.
