manifold Termojet with valves for 2 outlets, stainless steel

Termojet TJ-R-W manifold for 2 outlets with ball valves — stainless steel AISI 304, length 180 mm, connection G1" – G3/4". Shut-off valves on each outlet allow any circuit to be isolated without stopping the system. The optimal solution for small two-circuit projects where loop lengths are equal and precise flow balancing is not required.

Technical Specifications

Operating Principle

The heat carrier enters from the main line through G 1" and is distributed across the two circuits. Each outlet is fitted with a ball valve — a quarter turn opens or fully closes the circuit. This allows one loop to be isolated for repair, flushing, or seasonal shutdown without stopping the rest of the system. The M30×1.5 sockets on the return manifold accept standard thermal actuators for automatic control.

Difference from the flow meter version: valves are either open or closed — a "half-open" position is technically possible but does not provide precise flow control. Therefore, this manifold is suitable for systems where both loops have approximately the same length and hydraulic resistance.

Application Scenarios

• Apartment, 2 equal zones. Bathroom and toilet of the same size, or two adjacent bathrooms with equal loop lengths — ball valves are fully sufficient.
• Budget project. When the price of the solution matters more than precise balancing — TJ-R-W is cheaper than the flow meter version while retaining the same stainless steel body.
• Upgrade option. If precise balancing is needed later — upgrade to the 2-outlet manifold with flow meters.
• Underfloor heating from a heat pump. With two circuits of equal length and a low-temperature heat pump mode, ball valves are sufficient to manage the system.

Advantages

• Stainless steel AISI 304 — the same body as in the flow meter version, no compromise on material.
• Ball valves on each circuit — reliable shut-off without leakage, minimum hydraulic resistance when open.
• M30×1.5 — standard thread for mass-market thermal actuators without adapters.
• G 3/4" Eurocone — connection of PE-RT 16×2 or PE-Xa without welding.
• Complete assembly — valves with thermometers, air vents, drain valve included.

Underfloor Heating and Heat Pump

Two underfloor heating circuits from a heat pump are a common scheme for an apartment or small cottage. In low-temperature heat pump mode (35–45°C supply), ball valves are adequate for managing the system if the loops are balanced by design. For maximum heat pump efficiency and guaranteed balancing, consider the flow meter version. Details on system selection — on the Termojet heat pumps website.

Frequently Asked Questions

When are valves sufficient, and when are flow meters needed?
Valves are sufficient if the two circuits have the same or similar length — the difference in hydraulic resistance is minimal. If the loops differ significantly in length, the shorter one will "steal" the flow and the longer one will remain underheated. In that case, switch to the 2-outlet manifold with flow meters.

Can thermal actuators be installed on a manifold with ball valves?
Yes. The M30×1.5 sockets on the return manifold are designed specifically for thermal actuators. Ball valves and thermal actuators operate independently: the valve provides manual shut-off, the actuator provides automatic control via a thermostat signal. The system is housed in a manifold cabinet No. 00. If the boiler temperature exceeds 55°C, connect a mixing unit.
