Compact 6-way ball valve for four-pipe heating and cooling systems, designed to handle changeover or regulating duties with fewer components.
I installed the Apollo wall fan coil in our living room and I couldn't be happier. It's incredibly quiet—you barely notice it's running—yet it heats the space up super fast. Plus, the clean white design looks great on the wall
Whisper-Quiet Comfort
A sleek, modern design that blends perfectly into any room
APOLLO 6-Way Valve
This compact valve replaces up to four conventional valves and actuators, reducing material use and installation complexity in tight mechanical layouts.
It works as both a regulating valve and a changeover valve for heated or chilled ceilings and fan coils in four-pipe systems.
Its dual right-angled port design helps keep heating and cooling circuits separated without cross leakage.
Manufactured from dezincification-resistant brass CW602N or CW617N for long service life under demanding hydronic water conditions.
Kvs values can be tuned with exchangeable orifice plates to match the intended system flow and improve control accuracy.
Pairs easily with AKM 115(S) and AKF 112 or 113(S) actuators to create a complete and streamlined control assembly.
The APOLLO 6-way ball valve is a compact solution for four-pipe systems, handling both heating and cooling with a single 90-degree rotation instead of multiple separate valve assemblies.
A dezincification-resistant brass body and compatibility with VDI 2035 water quality guidance help support long-term reliability and corrosion resistance.
Exchangeable orifice plates allow the valve's Kvs value to be selected for the design intent, supporting better hydronic balance and efficient operation.
Its compact body, ISO 228 male threads, and optional fittings make the valve easier to install and service in modern hydronic control packages.
