Frequently asked questions
Does the blue and red finish differ in anything other than colour?
No. Types IVAR.6770 (blue lever) and IVAR.6778 (red lever) have the same dimensions, materials and operating parameters; the difference is only in the lever colour.
Can I regulate the flow with this valve?
No, the ball valve is intended only for full opening or closing. Operation in an intermediate position is not permitted by the manufacturer.
What should I 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 cause the valve body to tear during over-tightening.
In what position should I leave the valve when draining the system to prevent freezing?
If the system is drained due to the risk of freezing, leave the ball valve slightly open at 45°.
