Stainless steel 11-way manifold FERRO RSZTPX-11 with flow meters, thermostatic valves, drain valves and automatic air vents

FERRO RSZTPX-11 is an 11-way stainless steel hydraulic manifold designed to distribute and balance hot water for underfloor heating and multi-circuit heating systems. The manifold integrates individual flow meters for clear visual balancing, thermostatic valves for temperature regulation on each circuit, drain valves for convenient maintenance and automatic air vents to reduce air-related noise and performance loss. Its stainless steel construction provides corrosion resistance and long-term dimensional stability in domestic and commercial installations.

Advantages

The stainless steel body ensures resistance to corrosion and scaling while maintaining mechanical strength for stable operation. Built-in flow meters allow precise adjustment of flow rates for each loop, which simplifies hydraulic balancing and helps maintain even floor temperatures. Thermostatic valves give individual circuit temperature control, improving comfort and system efficiency. Drain valves and automatic air vents make routine maintenance and commissioning faster and safer.

Suitable for

• Underfloor heating systems with multiple heating loops
• Residential and light-commercial hydronic zoning
• Retrofit and new-build projects requiring circuit-by-circuit balancing
• Installations where compact, corrosion-resistant distribution is needed

Key specifications

• Number of outlets: 11 independently metered circuits
• Material: stainless steel manifold body
• Flow measurement: individual transparent flow meters on each outlet for visual balancing
• Control: thermostatic valves integrated per circuit for temperature regulation
• Maintenance features: drain valves for safe fluid removal and servicing
• Air management: automatic air vents to remove trapped air from the circuit
• Application: suitable for water-based underfloor and multi-circuit heating systems

How to use

Install the manifold in a dry, accessible location according to local plumbing and heating regulations, ensuring correct orientation and secure connections to supply and return piping. Connect each heating loop to an outlet and use the transparent flow meters to adjust flow rates until hydraulic balance and required room temperatures are achieved. Use the thermostatic valves to set desired temperature control per circuit. For draining and servicing, close the appropriate valves and use the drain valves provided to remove fluid safely. Check automatic air vents during initial fill and commissioning to purge trapped air.

Usage recommendations

Commission the manifold by performing a full system flush and degassing prior to operation. Use appropriate pipe fittings and sealing materials compatible with stainless steel. Periodically inspect flow meters, valves and air vents and replace or service components according to the system maintenance schedule to preserve performance and reliability.
