Frequently Asked Questions
Can this PVCu ball valve be used with hot water or steam?
The valve is generally suitable for cold and moderately warm fluids within the temperature limits of PVCu and FPM, but it is not suitable for steam or very high-temperature applications. Always check that the planned operating temperature falls within the recommended range for PVCu and FPM in your system.
Is the valve suitable for all chemicals?
No, while PVCu and FPM offer excellent resistance to many acids, alkalis and process chemicals, they are not compatible with every substance or concentration. You should consult a chemical compatibility chart for PVCu and FPM, and confirm suitability for your specific media, temperature and pressure conditions before use.
Do I need to cut the pipe to service or replace this valve?
In most installations you do not need to cut the pipe. The double union design allows the nuts at each end of the valve to be loosened so that the central valve body can be removed for inspection, cleaning or replacement while leaving the pipe connections in place.
