IBO installation valve for diaphragm vessels – for central heating and domestic hot water systems
3/4" valve from IBO is a practical installation component designed to connect diaphragm vessels in central heating (C.O.) and domestic hot water (C.W.U.) systems. It enables quick installation and removal of the vessel for maintenance or replacement and prevents fluid from being discharged automatically from the system during removal.
Key benefits
-
Faster servicing – remove the vessel without draining the entire system.
-
Safety – the valve stops the medium from escaping when the vessel is disconnected.
-
Versatile application – for C.O. and C.W.U. systems.
-
High resistance – operation up to 10 bar and 100°C.
Application
- Installation of diaphragm vessels in new and modernized systems.
- Easy disconnection of the vessel for inspection, maintenance, or replacement.
- Reduced risk of flooding during servicing.

Installation tips
- Before starting work, turn off the heat source and reduce the pressure in the system.
- Use suitable connection sealing (e.g. PTFE tape or sealing paste), ensuring a leak-tight connection.
- After installation, perform a leak test and restore the correct pressure in the system.
FAQ – Frequently asked questions about the IBO diaphragm vessel valve
What is this valve used for?
The IBO valve serves as an installation component for diaphragm vessels in C.O. and C.W.U. systems. It makes it easier to connect the vessel and quickly disconnect it for inspection or replacement.
How does the fluid discharge protection work?
When the vessel is removed, the valve stops the flow, preventing the medium from escaping automatically from the system. This speeds up servicing and reduces the risk of flooding.
Is the valve suitable for C.O. and C.W.U. systems?
Yes. It is designed to operate in both central heating and domestic hot water systems where diaphragm vessels are used.
What are the valve's operating parameters?
The maximum parameters are 10 bar pressure and a medium temperature of 100 °C.
How should the valve be installed correctly?
Disconnect the heat source and release the pressure, install the valve according to the system's flow direction, and then seal the connections. After installation, perform a leak test and set the correct system pressure.
