PRESSURE INDEPENDENT CONTROL VALVE (PICV)

  • Allows, in a single device, hydraulic balancing of the circuit and adjustment of the flow rate to the terminals.
  • Circuit balancing is carried out using an automatic regulator capable of working with a pressure differential of up to 4 bar at the valve ports
  • Possibility, during installation, of easily pre-adjusting the flow rate to between 10% and 100% of the nominal value using a graduated scale indicator.
  • Flow rate adjustment can take place using an actuator controlled by an external regulator, in accordance with the thermal load.
  • Extremely compact, suitable for installation even in small spaces.
  • Fitted for connection to pressure test gauges for checking the system operating parameters

FCU VALVES

The pre-assembled group for terminal units is compact and able to shut-off, adjust and filter the secondary circuit of the terminal unit. It also allows to perform maintenance and setting operations of the system. It allows the connection of fan coils, cold beams or ceiling conditioning systems with the main distribution network. Complete with insulation suitable for both heating and cooling. Available with Venturi device for flow rate measurement.

AUTO FLOW CONTROL VALVES

AUTOFLOW® devices are automatic flow rate regulators, which keep the flow rate constant in air conditioning and plumbing system circuits. They are used to automatically balance the plumbing system, guaranteeing the design flow rate to each terminal. The devices are available in both the flow rate regulator simple version and the shut-off ball equipped version.

TWO WAY & THREE WAY VALVES

Motorised ball valves allows both automatic shut-off and diversion of the thermal medium in air conditioning or water supply systems. The use of these components is particularly indicated in hydrothermal

systems thanks to the following features:

  • possibility of being installed upside-down;
  • possibility of being opened and closed thanks to the manual control lever on the actuator;
  • no seepage;
  • short operating times (valve – opening/closing);
  • can function with high differential pressures;
  • low head losses;
  • combination with any type of 3-contact actuator;
  • in the three-way versions, possibility of use in diversion or mixing mode.

AIR SEPERATORS

Deaerators are used to continuously remove the air contained in the hydraulic circuits of heating and cooling systems. The air discharge capacity of these devices is very high. They are capable of automatically removing all the air present in the system down to micro-bubble level. The circulation of fully deaerated water enables the systems to operate under optimal conditions, free from any noise, corrosion, localised overheating or mechanical damage. In the threaded versions it is available for installation on horizontal pipes, and with adjustable T-fitting for installation on horizontal and vertical pipes. Flanged and weld-end DISCAL® deaerators are supplied complete with hot pre-formed shell insulation to ensure perfect heat insulation when used in both hot and chilled water systems. Optional insulation is available for the threaded model with 3/4” and 2” drain.

AIR VENTS

Automatic air vent valves are designed to remove the air that accumulates in heating, air conditioning and refrigeration systems without the need for manual intervention. This prevents harmful phenomena that may compromise the life and the performance of the

Heating system and which include:

  • corrosion due to the oxygen;
  • pockets of air trapped in the heating emitters;
  • cavitation in the circulation pumps;
  • noise from air passing through the pipes.

These high capacity air vent valves are ideal for use in large piping systems and can also be installed in horizontal sections.

PREASSURE REDUCING VALVES ( PRV)

Pressure reducing valves are installed in residential water systems to reduce and stabilise inlet pressure from the water supply network which is generally too high and variable for domestic systems to work properly. The 533...H series was designed for small systems, such as apartments, and to protect water storages, where size and lack of noise are important aspects. This specific series of pressure reducing valves is certified according to the EN 1567 standard for operating with inlet water temperatures of up to 80°C.

THERMOSTATIC MIXING VALVES

The thermostatic mixing valve is used in systems that produce domestic hot water. It is designed to maintain the preset temperature of the mixed water delivered to the user outlet, when there are variations in the temperature and pressure of the hot and cold water at the inlet, or in the drawn-off flow rate. These devices are also available with fittings complete with strainers and check valves on the hot and cold water inlets

THERMAL BALANCING VALVE

The thermostatic regulator is used for automatic balancing of recirculation loops in domestic hot water distribution systems, so as to ensure that all parts of the system reach the required temperature. It is also equipped with a by-pass mechanism, to be used in the event of thermal disinfection against Legionella. The device is produced in a version complete with automatic thermostatic thermal disinfection function or fitted for disinfection against Legionella, with the possibility of installing a special cartridge for disinfection controlled by an actuator. The regulator complies with specifications by DVGW (according to standard W554) and by WRAS (UK).

ELECTRONIC MIXING VALVE

The electronic mixing valve is used in centralised systems that produce and distribute domestic hot water. Its function is to guarantee and maintain the temperature of the domestic hot water delivered to the user when there are variations in the temperature and pressure of the hot and cold water at the inlet or in the draw-off flow rate. This particular series of electronic mixing valves is equipped with a specific regulator that controls a set of programs for circuit thermal disinfection against Legionella. In addition it enables checking the temperature and time for thermal disinfection are actually reached and undertaking the appropriate corrective action. All the parameters are updated every day and logged, with temperatures recorded every hour. Depending on the type of system and habits of the user, it is possible to program temperature levels and operation times in the most appropriate manner. In addition, it is fitted for a monitoring and remote control connection.

BACKFLOW PREVENTERS

The charging unit assembly is composed of a shut-off valve with an inspectable strainer, a BA type controllable reduced pressure zone backflow preventer and a pre-adjustable filling unit. It is installed on the water inlet pipe in sealed heating systems and its main function is to maintain the pressure of the system stable at a set value, providing automatically a re-fill of the missing water. This product has the peculiarity of being pre-adjustable. That means it can be adjusted at a desired pressure value before the system filling stage. The backflow preventer is inserted to prevent the contaminated water of the closed heating circuit from flowing back into the domestic water supply network, in compliance with EN 1717 standard prescriptions. The device is proposed complete with pre-formed shell insulation and with a compact dimension design to make its hydraulic installation easier
