Product information

Description

Comap double regulating valve R859604 is a 1/2" x 1/2" two-way flow control valve engineered for precise hydraulic regulation in heating and plumbing systems. Designed for inline installation, the valve enables accurate balancing and fine adjustment of fluid flow between circuits. The compact construction and standardized connections make it compatible with boilers, radiators, distribution manifolds and other hydronic components where controlled flow is required.

Advantages

The valve offers two-way regulation for both coarse and fine flow adjustments, enabling stable hydraulic balance across a system. Its 1/2" x 1/2" dimensions and straightforward body design simplify installation in tight spaces. The product supports consistent flow control over a range of operating conditions and reduces the need for repeated manual adjustments during commissioning and maintenance.

Suitable for

  • Balancing heating circuits in residential or commercial boilers
  • Flow regulation to radiators and convectors
  • Distribution manifolds in multi-zone heating systems
  • Plumbing repair and retrofit jobs requiring precise flow control

Key specifications

  • Valve type: two-way regulating flow control
  • Connection size: 1/2" x 1/2" (inlet x outlet)
  • Application: hydraulic regulation in heating and plumbing systems
  • Mounting: inline, suitable for standard pipe fittings of matching size
  • Control: adjustable for coarse and fine flow balancing

How to use

Install the Comap double regulating valve inline with the supply or return pipework using appropriate fittings and sealants for 1/2" connections. Orient the valve according to the flow direction indicated on the body and ensure all joints are leak-free before system pressurization. Use the valve’s adjustment mechanism to set the required flow rate during system balancing—start with coarse settings, then refine with fine adjustments while monitoring temperature and flow indicators. After setting, check the system under normal operating conditions to confirm stable flow and absence of leaks.

Usage recommendations

For reliable operation, commission the valve as part of a complete hydraulic balancing procedure. Use compatible pipe materials and fittings rated for the system’s pressure and temperature. Periodically inspect the valve for leakage and recalibrate if system demands change or after maintenance work.
