Product information

Description

SiGMA-Li RSZTPX-3 is a stainless steel 3-way manifold engineered for hydraulic distribution in heating and cooling installations. The unit integrates flow meters for circuit balancing, thermostatic valves for temperature regulation, drain valves for maintenance, and automatic air vents for rapid degassing. Constructed from corrosion-resistant stainless steel, the manifold is intended for durable performance in underfloor heating, radiator circuits and small hydronic systems where precise flow control and straightforward servicing are required.

Advantages

The manifold combines calibrated flow meters and thermostatic control valves to enable accurate balancing and individual temperature adjustment of each circuit. Stainless steel construction provides improved corrosion resistance and mechanical strength compared with many brass alternatives. Built-in drain valves simplify maintenance and winterization, while automatic air vents reduce trapped air that can impair circulation and heat transfer. Compact layout and standardized connections support straightforward installation and integration into common hydronic layouts.

Suitable for

  • Underfloor heating systems with multiple zones
  • Small radiator circuits and low-temperature heating loops
  • Cooling distribution in light commercial or residential hydronic setups
  • Retrofit projects requiring accurate circuit balancing and easy servicing

Key specifications

  • Material: stainless steel body for corrosion resistance and durability
  • Configuration: 3-way manifold with three separate outlets for distribution
  • Flow control: integrated transparent flow meters for visual balancing and flow measurement
  • Temperature control: thermostatic valves on each circuit for individual regulation
  • Service features: drain valves for each circuit to enable flushing and maintenance
  • Air management: automatic air vents to remove trapped air and maintain hydraulic performance
  • Connections: standardized hydraulic fittings for common piping systems

How to use

Install the manifold in the system feed or return according to hydraulic design and local plumbing codes, ensuring proper orientation and secure connections. Use the flow meters to balance each circuit by adjusting the integrated valves until the desired flow rate is visible on the transparent indicators. Set the thermostatic valves to the required temperature levels for each zone. Open the drain valves when flushing or performing maintenance, and allow automatic air vents to purge trapped air during initial filling and commissioning.

Usage recommendations

For reliable operation, flush the system before installation to remove debris that can obstruct flow meters and valves. Commission each circuit after filling to confirm correct flow rates and verify that automatic air vents are expelling air. Follow local regulations for installation and, if necessary, use compatible fittings and isolation valves to allow future servicing without system drain-down.
