Manifold Valvex K5 PLUS-10 G1–G3/4 n=10, steel bar, flowmeters and thermostatic valve included

Valvex K5 PLUS-10 is a 10-circuit heating manifold designed for balanced distribution of hot-water in underfloor or radiator heating systems. The manifold features inlet/outlet connections in sizes G1 and G3/4 and is mounted on a sturdy steel bar for reliable mechanical support. The delivery set includes G1/2 flowmeters, a G1/2 thermostatic valve, a safety group for the manifold, a G1×2 piece steel bar mount, a G1/2×G3/4 reducing coupling and V-PEX 16×3/4 connector to simplify installation and hydraulic balancing.

Advantages

The Valvex K5 PLUS-10 manifold provides precise flow measurement and individual circuit control through integrated flowmeters and a thermostatic valve, enabling accurate balancing of up to ten heating loops. Steel-bar mounting ensures stable alignment and easy handling during installation. Included fittings and connectors reduce the need for additional components and streamline system commissioning.

Suitable for

• Underfloor heating systems with up to ten circuits
• Small to medium radiator heating installations requiring centralized distribution
• Projects where hydraulic balancing and flow measurement are needed
• New builds and renovations requiring a compact manifold assembly

How to use

Install the Valvex K5 PLUS-10 manifold on its steel bar mount at the designated manifold cabinet or mounting location. Connect the primary supply and return to the inlet and outlet ports (G1 and G3/4 respectively) and attach each circuit to the corresponding outlet using appropriate piping and the supplied V-PEX connector and reducing coupling as required. Use the integrated flowmeters to set and monitor individual loop flow rates and the thermostatic valve for temperature control. Ensure the safety group is connected to the manifold according to system layout and local regulations.

Usage recommendations

Before commissioning, flush and fill the heating system, then vent each circuit and verify flowmeter readings while gradually adjusting balancing valves. Use corrosion-inhibited water where recommended by system designers and check all threaded connections for proper sealing. For optimal performance, combine the manifold with compatible actuators and controls and follow installation guidelines from a qualified heating professional.
