The FlowCal™ automatic flow balancing valve maintains a constant fixed flow rate within varying system differential pressure ranges. Operation is fully automatic requiring no manual adjustment. The 121 series utilize an exclusive, interchangeable flow cartridge, made of anti-scale, low noise polymer for use in cooling and heating systems. The FlowCal 121 series automatic flow balancing valves are available with integral shut-off ball valve and optional factory-installed pressure and temperature test ports.
- Features
- The FlowCal automatic flow balancing valve guarantees a constant flow rate when the upstream/downstream pressure differential varies.
- Polymer flow cartridge: The flow rate cartridge is made of an anti-scale polymer, specially engineered for use in cooling, heating and domestic water systems, to prevent mineral buildup. Its mechanical behavior is excellent in a wide range of working temperatures, it features high resistance to the abrasion caused by continuous fluid flow, it is insensitive to the deposit of scale and is fully compatible with glycols and additives used in circuits.
- Replaceable cartridge: The internal flow cartridge can be removed easily from the valve body for inspection, cleaning or replacement.
