## Long description

CALEFFI shut-off valve manifold O3/4x2 O23P.1,5-18 is a compact plumbing manifold designed for installation in heating and domestic water systems. It includes two individually controllable shut-off valves that allow isolation of each branch without interrupting the entire system. The manifold is intended for inline mounting and provides reliable flow control for maintenance, repairs, and balancing of piping circuits.
Advantages
The CALEFFI manifold offers precise shut-off capability for two outlets, enabling safe isolation of individual circuits during servicing. Its design supports straightforward installation and reduces downtime by avoiding the need to drain the full system. Constructed from durable materials suitable for typical heating and potable water applications, the unit ensures consistent operation and simplifies routine maintenance.
Suitable for
Residential and small commercial heating loop distribution
Domestic hot and cold water branch isolation
Localised maintenance and repair without system drainage
Balancing and commissioning of two parallel piping circuits
Key specifications
Connections: two outlet branches with O3/4 thread size
Number of shut-off valves: 2 independently operated valves
Application: heating systems and domestic water installations
Mounting type: inline manifold for pipe integration
Function: manual shut-off and isolation of circuits
How to use
Install the CALEFFI shut-off valve manifold in the pipeline at a location that allows access to the two outlet valves. Connect the supply and outlet pipes using compatible O3/4 fittings and ensure all joints are sealed according to local plumbing standards. Operate each valve manually to open or close the corresponding branch; verify tightness after installation by gradually pressurising the system and checking for leaks. Use the valves to isolate circuits during maintenance, repairs, or when balancing flow between branches.
Usage recommendations
For safe and reliable operation, follow local plumbing and heating regulations during installation and commissioning. Use appropriate sealing materials on threaded connections, avoid excessive torque on valve bodies, and perform pressure and leak tests after installation. Periodically operate the shut-off valves to prevent seizing and inspect for signs of wear or corrosion in accordance with routine system maintenance.
