A majority of the products offered can be ordered in either AISI 12L14 Carbon Steel or AISI 316L Stainless Steel depending on the intended application and sampling fluid. Refer to the fluid compatibility chart to determine the best valve and seal material for your application.
AISI 12L14 Carbon Steel is the economical valve body material and is well suitable for the majority of applications and installs. AISI 12L14 is suitably rugged to withstand the harsh environments for use on mining, construction, and other similar off-road equipment. All carbon steel valves are electroplated with a Zinc-Nickel alloy plating to provide superior protection against road salts and red rust.
Enhanced Nickel/ Nickel Alloy Electroplating on Carbon Steel
The new nickel alloy plating adopted as an automotive standard allows a cost effective solution to environmental corrosion. Many vehicles that travel in cold climates tend to experience greater corrosion on steel parts due to the harshness of road salts used in cold weather. Checkfluid has products including the KP, KST and L Series coated with a dark silver colored electroplating that is over five times more corrosion resistant than the current trivalent zinc plating. Both plating types comply with the RoHS guidelines as environmentally friendly. Additional application-specific plating options are available.
Please contact Checkfluid for more information.
AISI 316L Stainless Steel is the material of choice for applications requiring greater resistance to chemicals and environmental conditions than either the AISI 12L14 Carbon Steel or the AISI 304L Stainless Steel. AISI 316L Stainless Steel valves are mostly used on sea vessels where they are subjected to salt water and mists for extended periods of time. Other industries such as food and beverage producers, pulp and paper mills, pharmaceutical, and chemical handling facilities use stainless steel valves due to its chemical inertness and durability.
AISI 304L Stainless Steel is available as a more cost effective solution to the AISI 316L Stainless Steel and can be used to protect against mild chemicals and provide good corrosion protection. AISI 304L Stainless Steel is suitable for use on coastal regions to withstand the salt environment and for inland uses where greater corrosion protection is desired. For applications dealing with fresh water, AISI 304L stainless steel is the most economical choice for corrosion protection and performance.
