IVAR.CS 553 - return manifold with shut-off valves
The IVAR.CS 553 category includes brass collectors with integrated closing valves for use in underfloor heating systems. These manifolds are designed for the ON/OFF control of return water flow and are suitable for installation in systems with floor and radiator heating. They feature side inputs of 1" F and 5/4" F, and outputs of 3/4" EK with a 50 mm spacing between outlets. The units are constructed from CW617N brass and operate at a maximum temperature of +120 °C under PN 10 pressure conditions.
How to choose
- Select the number of ways (2 to 12) based on the number of heating loops in the system.
- Confirm the input and output thread types (1" F, 5/4" F, and 3/4" EK) match the system piping.
- Ensure compatibility with electrothermal heads such as IVAR.TE 3040, IVAR.TE 4040, IVAR.TE 3041, and IVAR.TE 4041 if automated control is required.
- Verify the operating temperature and pressure (T = +120 °C, PN 10) align with the system requirements.
Frequently asked questions
Can the manual valve heads be replaced with electrothermal heads?
Yes, the manual heads can be replaced with compatible electrothermal heads such as IVAR.TE 3040, IVAR.TE 4040, IVAR.TE 3041, and IVAR.TE 4041.
What is the recommended pre-startup procedure for these manifolds?
Before commissioning, especially in mixed floor and radiator systems, the entire heating system should be flushed according to the manufacturer's instructions. It is also advised to treat the system with GEL.LONG LIFE 100.
