2-way stainless steel manifold FERRO RSZTPX-2 with flow meters, thermostatic valves, drain valves and automatic air vents

FERRO RSZTPX-2 is a 2-way stainless steel manifold engineered for hydronic heating and cooling circuits. It integrates flow meters for transparent flow balancing, thermostatic control valves for individual temperature regulation, drain valves to simplify maintenance and automatic air vents for reliable degassing. The compact stainless steel construction ensures corrosion resistance and long service life while enabling use in underfloor heating systems or small radiator groups where precise circuit control is required.

Advantages

The manifold combines multiple functions in a single assembly: visual flow metering, thermostatic valve control and service-friendly drain points together with automatic air separation. Stainless steel body provides durability and reduced risk of corrosion in mixed-water installations. Integrated flow meters allow quick and accurate hydraulic balancing without additional measuring tools, and the thermostatic valves permit temperature adjustment at the manifold for each circuit. Built-in drain valves and automatic air vents reduce installation and servicing time.

Suitable for

• Underfloor heating installations with up to two circuits
• Small radiator groups requiring individual flow and temperature control
• Hydronic cooling circuits in residential or light-commercial projects
• Retrofit and new-build projects where compact manifold design is needed

Key specifications

• Configuration: 2-way manifold
• Material: stainless steel manifold body
• Integrated components: flow meters, thermostatic control valves, drain valves, automatic air vents
• Mounting: wall- or cabinet-mountable with supplied fixing points (subject to installer preference)
• Functionality: hydraulic balancing, circuit temperature regulation, degassing and draining

How to use

Install the FERRO RSZTPX-2 manifold in accordance with local plumbing and heating codes and manufacturer installation practices. Connect supply and return headers to the heat source and individual circuits to the manifold outlets. Use the integrated flow meters to set and verify flow rates for each circuit during commissioning. Adjust thermostatic control valves to achieve the required circuit temperatures. Operate the drain valves for system draining during maintenance and allow the automatic air vents to remove trapped air during filling and initial operation.

Usage recommendations

During commissioning, perform hydraulic balancing using the built-in flow meters and record settings for future maintenance. Use corrosion-inhibiting additives compatible with stainless steel if recommended by the heating system designer. Periodically check automatic air vents and drain valves for proper function; clean or replace replaceable parts according to service intervals. Ensure thermostatic valve heads are compatible with the manifold or installed according to the valve manufacturer’s guidance.
