FAQ

Question?
What does the F07/F10/S17 marking on the top flange mean?

This refers to the ISO 5211 standard for mounting actuators. F07 and F10 are two different standard bolt circle patterns for the mounting flange, making it versatile. S17 indicates the female drive on the actuator should be a 17mm square to fit the valve stem.

Question?
Is the 1.4408 stainless steel material suitable for use with seawater or chemical applications?

Yes, 1.4408 (equivalent to CF8M or AISI 316) is an austenitic stainless steel with molybdenum, which provides excellent resistance to pitting and crevice corrosion, making it very suitable for marine environments, chlorinated water, and a wide range of chemicals.

Question?
What type of seats are typically installed in a PY4 valve rated for 200 deg. C?

For a maximum temperature rating of 200 degrees Celsius, these valves are typically fitted with reinforced PTFE (TFM, PFA) or other high-performance polymer seats to ensure a tight seal and long service life at elevated temperatures.
