For Use With: Acetone, Ammonia, Butane, Carbon Dioxide, Citric Acid, Diesel Fuel, Ethylene Glycol, Fuel Oil, Gasoline, Hydrochloric Acid, Isopropyl Alcohol, Kerosene, Methanol, Methyl Ethyl Ketone, Mineral Spirits, Natural Gas, Nitric Acid, Nitrogen, Oil, Oxygen, Phosphoric Acid, Propane, Salt Water, Soap Solutions, Sodium Hydroxide, Sodium Hypochlorite, Sulfuric Acid, Toluene, Water, XylenePiston Material: PTFE Plastic Spring Material: PTFE Plastic 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.
Flow coefficient ( Cv ) (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
