Manifold INVENA PROV-9 (PP-05-902) with 2 circuits, rotating valves and thermostatic drain

INVENA PROV-9 manifold PP-05-902 is a compact distribution unit designed to manage two separate heating or domestic water circuits. The unit integrates two rotating control valves and a thermostatic drain to provide straightforward temperature regulation and secure draining. Engineered for installation in underfloor heating systems or small multi-zone setups, the manifold delivers practical circuit separation and simple service access in a small footprint.

Advantages

The PROV-9 manifold combines independent circuit control with a thermostatic drain to maintain stable water temperature and protect the system during draining. Rotating valves enable fast and intuitive shut-off for each circuit, simplifying maintenance and balancing. Its compact design reduces installation space requirements and supports tidy plumbing layouts, while corrosion-resistant materials help ensure long-term reliability under normal operating conditions.

Suitable for

• Two-zone underfloor heating systems
• Small multi-zone radiator or convector circuits
• Domestic hot water distribution with separate supply loops
• Boiler or heat pump installations requiring compact manifold solutions

Key specifications

• Number of circuits: 2 independently controlled circuits
• Valve type: rotating shut-off valves for each circuit
• Drain system: thermostatic drain for temperature-regulated draining
• Application: suitable for underfloor heating and small multi-zone systems
• Design: compact manifold body for space-efficient installation

How to use

Install the manifold in a location that allows easy access to the rotating valves and drain connection. Connect supply and return piping for each circuit according to the system layout and local plumbing standards, ensuring correct flow direction. Use the rotating valves to open or close each circuit during commissioning, balancing, or maintenance. Operate the thermostatic drain when temperature-controlled draining is required; follow the manufacturer's guidance on safe draining procedures to avoid scalding and to protect system components.

Usage recommendations

Flush and clean the system before connecting the manifold, and install appropriate strainers and filters upstream to reduce the risk of particulate contamination. During commissioning, balance flows for each circuit and verify thermostatic drain function. Perform periodic inspection of valve operation and connections, and service according to local codes and equipment manufacturer instructions.
