Frequently asked questions
Does the blue and red version differ in anything other than colour?
No. Types IVAR.6771 (blue lever) and IVAR.6779 (red lever) have the same dimensions, materials and operating parameters; the difference is only in the lever colour.
Can I use this valve to regulate the flow?
No, the ball valve is intended only for full opening or closing. Operation in an intermediate position is not permitted by the manufacturer.
What to use to seal the threads during installation?
The manufacturer recommends Teflon tape, string or thread, or sealing pastes and gels. Hemp fibre is not recommended, as it may tear the valve body during over-tightening.
In which position should the valve be left when draining the system for frost protection?
If the system is drained due to the risk of freezing, leave the ball valve slightly open in the 45° position.
