Manifold Termojet with valves for 9 outlets, stainless steel

The Termojet TJ-R-W manifold with 9 outlets and ball valves — stainless steel AISI 304, length 530 mm, connection G1" – G3/4". Nine independent shut-off valves allow isolation of any circuit without stopping the system. The choice for large projects where room layout allows loops of approximately equal length and precise flow balancing is not a priority.

Technical Specifications

Operating Principle

The heat carrier enters through G 1" and is distributed across nine circuits. Each outlet has a ball valve: a single 90° turn fully opens or closes the circuit. This is indispensable during system start-up (filling circuits one by one), maintenance (flushing an individual circuit without stopping the rest), or temporarily isolating a zone. The M30×1.5 sockets on the return manifold accept actuators for automatic control from room thermostats.

For a system with 9 different loops of varying length, the 9-outlet manifold with flow meters is recommended — it provides precise balancing based on rotameter readings. The manifold with ball valves is optimal when loops are designed to be approximately equal.

Application Scenarios

• House with equal loops. A project where the installer calculates and lays loops of 80–100 m each in advance — the valves are sufficient for control and maintenance.
• Staged system start-up. 9 circuits are filled with heat carrier one at a time — ball valves allow isolation of sections not yet filled.
• Zone isolation. A terrace or unoccupied zone can be shut off in winter with a valve without affecting other rooms.
• Heat pump + underfloor heating. Nine circuits from the heat pump in a uniformly designed system — valves enable zone control and maintain low supply temperature for maximum COP.

Advantages

• Stainless steel AISI 304 — identical body material to the flow meter version, no compromise on base quality.
• Nine ball valves — reliable full shut-off without leakage, minimum resistance when open.
• M30×1.5 — standard thread compatible with mass-market actuators without adapters.
• G 3/4" Eurocone — connection for PE-RT 16×2 or PE-Xa without welding.
• Complete assembly — valves with thermometers, air vents, drain valve included.

Underfloor Heating and Heat Pump

Nine circuits from a heat pump allow heating the entire house at a heat carrier temperature of 35–45°C — this is where the heat pump achieves COP 4–5. Ball valves on the manifold provide independent control and maintenance of each zone. If loops vary in length and precise flow adjustment is needed — use the flow meter version.

Frequently Asked Questions

Which cabinet to choose for a 9-outlet manifold with ball valves?
The 9-outlet manifold fits in manifold cabinet No. 03 (designed for 8–10 outlets, 715 mm). If a pump-mixing unit is installed nearby — choose a cabinet accounting for its dimensions or install the unit separately.

Is this manifold suitable if all circuits are of different lengths?
If the difference in loop lengths is significant (more than 20–30%) — the 9-outlet manifold with flow meters is recommended: it provides precise balancing based on rotameter readings and ensures uniform heating of all zones. Also install a mixing unit if the boiler or heat pump delivers temperatures above 55°C.
