## Summary description

Stainless steel 3-way manifold by FERRO (model SN-RZPU03S) for hydronic heating systems. Equipped with thermostatic valves for temperature control, flowmeters for balancing, automatic air vents for degassing, drain valves for maintenance and 3/4" nipples for connections. Designed for distributing and regulating hot water flow in radiators, underfloor heating or other closed-loop systems.

## Long description

FERRO 3-way stainless steel manifold SN-RZPU03S is designed for distribution and regulation of hot water in closed hydronic heating systems. Constructed from stainless steel, the manifold integrates thermostatic valves for temperature control, flowmeters for hydraulic balancing, automatic air vents for system degassing and drain valves for convenient maintenance. The unit includes 3/4" nipples for secure connection to piping and is suitable for use with radiators, underfloor heating circuits and other closed-loop heating installations.
Advantages
The stainless steel construction provides corrosion resistance and long service life in domestic and light-commercial heating systems. Thermostatic valves allow accurate temperature regulation on each circuit while transparent flowmeters enable quick visual balancing during installation and adjustments. Automatic air vents reduce air accumulation and help maintain hydraulic efficiency, and the integrated drain valves facilitate safe and simple system draining for maintenance or repairs.
Suitable for
Domestic and small commercial radiator systems
Underfloor heating manifolds and multiple-zone floor circuits
Hydronic closed-loop heating circuits requiring individual circuit control
Retrofitting or new installations where compact manifold with integrated fittings is needed
Key specifications
Material: stainless steel body
Number of ways: 3-way manifold
Valves: thermostatic control valves on each circuit
Flow indication: transparent flowmeters for each outlet
Air management: automatic air vents integrated
Maintenance: integrated drain valves for each circuit
Connection nipples: 3/4" threaded nipples for piping
Application: designed for closed hydronic heating systems
How to use
Install the manifold on a stable support or within a mounting frame according to hydronic design and local plumbing codes. Connect the supply and return lines to the corresponding inlet and outlet ports, using appropriate sealing and torque for the 3/4" nipples. Use the thermostatic valves to set target temperatures per circuit and adjust the flowmeters during commissioning to balance flow rates across circuits. Open the automatic air vents during initial fill and bleeding cycles to remove trapped air; close when degassing is complete. Use the drain valves to safely isolate and drain individual circuits for maintenance.
Usage recommendations
During commissioning, perform stepwise balancing: set thermostatic valves to required positions, then fine-tune flows with the flowmeters. Periodically check air vents for proper operation and inspect valves and connections for leaks. Use corrosion-inhibiting additives in closed systems only if compatible with stainless steel components and following system manufacturer guidance.
