Safety Relief Valve

LK 514 MultiSafe

• O-ring connection suitable for LK’s range of valves

• From 1.5 to 10 bar

• Protect your boiler against overpressure

LK 514 MultiSafe is a high lift, soft sealing safety relief valve for

tap water installations as well as heating, recycling and cooling

systems with thermal expansion only. The valve must not be

used for steam. The outlet is fitted with compression fitting for

simple installation of a discharge pipe.

Turn the knob counter-clockwise 1⁄4 turn until a faint “click” is

heard. Let the water flush through briefly, then turn another 1⁄4

turn until a stronger “click” is heard and the valve closes.

This two-step opening function makes it possible to use the

safety valve discharge pipe to drain e.g. a water heater.
