Stainless Steel Ball Valves Series 502SS
Advantages
Parker’s Cast Body is manufactured from CF-8M Stainless Steel, the
cast equivalent of 316 Stainless Steel. They are ideal for corrosive
environments such as chemical plants and refneries. The full fow
design assures maximum operating effciency. The reinforced PTFE
seats and seals, coupled with the 316 Stainless Ball and blow-out proof
stem, result in the utmost reliability. These ball valves are available in
1/4", 3/8", 1/2 (502SS), and 3/4”, 1”, 1-1/4”, 1-1/2” and 2” (500SS)
female pipe sizes.
Applications/Approvals
Parker’s industrial ball valve product line is intended for general
purpose use. Please be aware that ball valves are intended for use in
the fully open or closed positions. Depending on application conditions,
throttling of the valve may result in premature seal failure and/or
inability to turn the valve handle.
Applications include chemical plants, refneries, steel mills, industrial
fuel lines and agricultural equipment. Meets material requirements of
NACE MR-01-75.
