OPTIMA IVAR.DV 023 straight bathroom lockshield valve – 1/2" × M24, chrome
Code: 530009CHROMProduct detailed description
Return valve for bathroom radiators
The IVAR.DV 023 belongs to the OPTIMA range of bathroom radiator valves, which combines function with a neat appearance. The straight valve screws into the radiator with its 1/2" male thread and connects to the pipework via the M 24 × 1.5 thread using a compression fitting for copper or plastic pipe. It pairs with the OPTIMA IVAR.DV 013 thermostatic valve in the same finish.
Functions
- regulation of the water flow through the radiator or complete shut-off
- isolation of the radiator without draining the whole system
- calibrated orifice with six positions (Kv 0.1 to 0.6), set with a 13 mm spanner
- contains a thermostatic insert, so flow and return can be connected either way
- the protective cap guards the thread during installation and also serves for shut-off
Materials and installation
The body is made of chrome-plated CW617N brass, the seals of peroxide-cured EPDM and the head of ABS plastic; the IVAR.AVK 01 adapter is part of the valve. The valve is rated for PN 10, a differential pressure of 1 bar and +100 °C. Seal the threads with PTFE tape, cord or thread, sealing paste or gel, not hemp. Before commissioning, the entire heating system must be flushed.

Frequently asked questions
What is the OPTIMA IVAR.DV 023 lockshield valve for?
It is fitted to a bathroom radiator, restricts or fully shuts off the flow and allows the radiator to be isolated without draining the system. It is used together with the OPTIMA IVAR.DV 013 thermostatic valve.
How is the flow set?
Turn the plug with a 13 mm spanner until the mark shows the designed position 1 to 6. Position 1 gives the lowest flow and position 6 the highest; intermediate positions cannot be set.
What should I seal the threads with?
The manufacturer recommends PTFE tape, cord or thread as well as sealing pastes and gels. Hemp is not recommended, as over-packing can crack the brass body.

IVAR designs, develops and manufactures highly energy-efficient heating and plumbing systems. We have over 10,000 catalogue items - mass-produced products and unique items - in addition to customised systems and combinations of complex products. And it’s all “Made in Italy”.
Vision
To make life easier for our clients, our clients' customers and our employees, thanks to our ability to be constantly innovative.
Mission
To design and manufacture advanced hydronic solutions that reduce installation complexity and energy consumption.
“Made in Italy” adds value
IVAR has been producing heating and plumbing system components since 1985: valves for heating bodies, direct heat metering modules, heat cost allocators, pipes and fittings, substations for heating systems, distribution manifolds, radiant panel systems, and components for solar and geothermal systems. And it’s all “Made in Italy”.
Over 200 people are employed at our manufacturing facilities in Prevalle (in northern Italy’s Brescia province). The site has been designed to streamline our many production and operational stages.
The Italian headquarters also acts as a hub for the wider IVAR Group, set up with the goal of distributing products beyond Italy’s borders. The group now has 11 branches, in Australia, Belgium, China, Germany, the United Kingdom, the Czech Republic, Romania, Slovakia, Spain, the United States and Tunisia.
Know How
Research, development and numerous laboratory tests guarantee that our clients’ requests can be translated into new high-efficiency products.
The stages required for production take place internally, beginning with hot forming, which is carried out at our subsidiary Valmon Stampati. Our continuous implementation of projects under the Industry 4.0 initiative also allows us to take full advantage of new releases in technology and IT to improve our manufacturing efficiency.
As a company, IVAR is constantly evolving. Every day, we invest in strengthening our products, in improving our production processes and in attaining new patents and certifications.
