This is vital in avoiding unnecessarily early replacement of your heater/chiller and more major issues, such as flooding, by maintaining a steady system volume.

Our various types of pressure reducing valves can address all application requirements: fast response, high flow capacity, stability, accurate pressure regulation, and much more. Find detailed information in the technical documents.

Waterpressureregulator

Our pressure reducing valves efficiently regulate the pressure in one part of a circuit to a pre-determined setting, while allowing the rest of the system to function at full system pressure.

Farmers need agricultural machines that deliver the same high productivity every season. Hydraulic solutions from Danfoss ensure world-class performance from each machine, and a comfortable, stress-free working environment for their operators.

Before seeking a quote for your project’s expansion vessel, it is recommended that you compile data on the following factors, to be shared with your supplier:

Now that you’re equipped with the information your supplier needs to identify the right tank for your system, you are ready to size and install the tank(s) for your upcoming project.

Higher flow rates will mean that in the event of excessive expansion and contraction, there is a greater risk of problems occurring within the system as the system’s components are bearing a greater load.

Expansion tanks compensate for fluctuating water pressure due to temperature changes within heating  water and chilled water systems. By containing expanded water and expelling water to compensate for contraction, expansion tanks will maintain the water pressure of your heater/chiller.

PRVvalve

Our total systems approach integrates advanced Danfoss hardware and software to deliver exceptional work function control.

Space is limited on construction sites, and there are people working everywhere. Contractors need machines that can safely maneuver in a tight spot. At the same time they still need to be powerful enough to get the job done. At Danfoss, we deliver the components, software, and controls that enable your machines to run safely, efficiently and effectively.

Lawn and turf machines must adapt to their surroundings and the season – becoming sweepers or snow blowers as required. At Danfoss, we make hydraulic solutions to provide that flexibility and ensure safe and efficient operation.

Rough, sloping terrain and cramped working conditions call for robust and reliable forestry machines. We make sure you can manage everything from cutting trees and transport to preparing the forest floor for replanting. We have the smart hydraulic solutions your machines need for precise and efficient forestry operations.

Expansion tanks that are smaller than ideal for your system will result in an inadequate ability for the tank to absorb expanded water, defeating the tank’s purpose and creating excessive stress on your plant equipment. Expanded water volume needs somewhere to go, and if your tank can’t facilitate it, it may result in ruptured pipes, creating pump cycling, splitting bellows and making relief valves excessively blow off – causing unwanted spillage and related hazards.

Every project’s HVAC system has its unique specifications and parameters. The system’s expansion tank must be sized accordingly, and has important responsibilities – including pressure maintenance, compensating for changes in volume, and preventing water losses. This makes correctly sized and installed expansion tanks vital for a system to function reliably.

An expansion tank is a small pressure vessel used to protect closed-water heating systems from excessive pressure. This is done using a bladder that expands with water as the system’s total volume expands with heating.

The water in your system will expand and/or contract more drastically, the broader its temperature range is. For this reason, a larger temperature range will correlate to the need for a larger expansion vessel.

While it is often recommended to have extra volume in case of future system expansion, there is the potential drawback of arbitrarily restricting plant room space with a tank that is larger than needed.

The higher the installation point of your expansion tank in relation to the rest of your system, the less pressure your tank should be set to. The reverse is also true – high tank pressure is needed when the expansion tank is beneath the rest of the system.

Advanced hydraulic systems from Danfoss deliver the machine performance that ensures road builders can meet their deadlines.

Regulatingvalve

Ensure optimal pressure for your hydraulic functions with our range of pressure reducing valves. Whether you prefer standard reducing or reducing/relieving valves, we've got you covered. Tailor your circuits effortlessly with our versatile selection, designed to meet your unique needs. Experience precision and reliability with our pressure reducing valves for peak hydraulic performance.

As a rule of thumb, higher system volume means higher system expansion volume, which requires a larger tank. This works with the capacity (kW) of your boiler and/or chiller – which primarily influences your system’s volume.

Cartridge pressure reducing valves are designed for durability and reliability, effectively regulating pressure to certain functions. This will result in a long operational life for your hydraulic systems by ensuring that your motors, cylinders, etc are not operated outside of their designed parameters.

PVG 32 is designed for maximum flexibility configurable as an advanced electrically controlled proportional valve. As well as a load sensing directional control valve.

HVAC expansion tanks come pre-charged at a default pressure rating, which is adjustable and should be matched to your minimum system pressure (static pressure). Most tank-related faults on site are caused by installers failing to set pre-charge correctly, which is an essential component of accurate commissioning that should be conducted by the site technician. It is strongly advised not to arbitrarily install an expansion tank with its factory default pressure setting, as this factory setting is not a one-size-fits-all pressure level.
