Set of two ball valves with union 1" IVAR.9723 R
Code: 9723R666Product detailed description
The 1" IVAR.9723 R set contains two ball valves with union. One is fitted to the inlet of the supply manifold and the other to the outlet of the return manifold, so the flow and return pipes of the manifold assembly can be shut off independently.
Design
- size 1" (DN 25), threads to ISO 228/1 (DIN 259)
- union with male thread on one side, female thread on the other (M/F)
- butterfly handle operation, 90° turn, handles in red and blue
- body, ball and end connector in nickel-plated brass CW617N, PTFE ball seal, EPDM O-ring, lacquered aluminium handle
- overall valve length 95.5 mm, spanner size 38 mm
Application
The valves are suitable for cold and hot water and compressed air lines in homes, industry and agriculture. The medium must not be aggressive. For the 1" size the maximum operating pressure is PN 30 and the temperature range is −20 to +120 °C.
Maintenance: always keep the ball valve fully open or fully closed – it is not intended for flow regulation. Operating it regularly through its full travel (once or twice a quarter on water lines) reduces deposits on the ball seal and keeps the valve tight for longer.
The IVAR.9723 R series also includes 3/4" and 5/4" sets.

Frequently asked questions
What is the IVAR.9723 R 1" set of two ball valves used for?
The valves are fitted to the manifold inlet and the return manifold outlet, so the supply and return can be shut off separately. The 1" size corresponds to nominal diameter DN 25.
Can the ball valve be left partly open to regulate the flow?
No. Ball valves are used only fully open or fully closed and are not designed for regulation.
How can the service life of the seals be extended?
Operate the valves regularly through their full travel, once or twice a quarter on water lines. Fewer deposits then build up on the ball seal.
What pressure and temperature can the valves withstand?
For the 1" size the maximum operating pressure is PN 30. The medium temperature can range from −20 to +120 °C.

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.
