Buy Belimo Control Valves & Motorization Ball Valves

Offering services in air and water solutions, the Belimo USA Company is internationally renowned for their high quality, reliable HVAC parts and tools. Belimo control valves for HVAC systems have always been especially acclaimed, due to their simplicity and high-standard value.

Belimo Control Valves include:

  • Belimo control valves for heating
  • Belimo control valves for ventilation
  • Belimo control valves for refrigeration
  • Belimo control valves for air conditioning
  • Belimo shut-off valves
  • Belimo change-over valves
  • Belimo motorization ball valves

Belimo control valves are used in general HVAC systems, and they require a pipe connector. Pipe connectors come in three forms:

  • Female screw thread (or internal threads)
  • Male screw threads (or external threads)
  • Flange connectors

Most products from the Belimo valve control range include both 2-way and 3-way versions, except for the pressure independent characterized Belimo control valve, models PN16 and DN 15, which only have the option of choosing a 2-way setting. Other Belimo control valve types include the Belimo control ball valve with a rotary actuator and the globe valve with a linear actuator.

Belimo Motorization Ball Valves

Belimo motorization ball valves, a distinct category of valves, are often referred to as quarter turn valves. They open by turning a handle attached to a ball inside the valve, hence the name. The ball includes a port or a hole that blocks flow through the valve and once the port is in line with the ends of the valve, flow will be unconfined and be released. Belimo motorization ball valves are manufactured from a large array of alloys, metals, plastics or ceramics, depending on the environment it will be used in and the product model. Because the ball will be the subject of high pressures and flow stresses, the ball inside the valve needs to be more durable, so some motorization ball valves are chrome plated to increase hardiness. The liquid passageway is constructed so that if it’s not in line with the ends of the valve, no spills occur, protecting the valve and the system you are using it for.

Shut-off and change-over Belimo control valves also require one of the three pipe connectors (female screw thread, male screw thread or flange) and they can be either ball operated valves with a rotary actuator or open-close butterfly valves with a rotary actuator, the last model only having a 2-way option. When buying Belimo motorization ball valves, you can choose a 2-way model (open-close model) or a 3-way model (change-over model)

Take note that ordinary Belimo motorization ball valves (Their models or other manufacturer models) are unsuitable as control devices. In order to ensure good stability of control, a hydraulic controlling component must hold a flow feature of the heat exchanger in the HVAC system. The company reduced this problem by introducing a “characterizing disc” in the inlet of the control valve, which changes the valve’s characteristic to the equal-percentage needed.

Characterized Belimo control valves have a square stem head for easier attachment with their actuators. Their simple direct mounting system uses a central screw and the rotary actuator is installed in three or four different positions, depending on your needs and the space you have available. All size control valve models can be connected to a mounting flange pipe. The structure of the valve’s body and the ball and stern are made out of stainless steel, making them more resistant in harsh environments, the kind of environments that are found in HVAC systems. Characterized Belimo control valves can be used for home, commercial and industrial HVAC systems.

Belimo open-close ball valves handle cold and hot water flows and have a shut-off function and a 2-point control system. They are handled by a rotary actuator, which in turn is controlled by an open-close signal, given by your manual operation of the valve’s lever. Change-over valves on the other hand, are used for the changing over of cold and hot water fluxes in ventilation and heating systems, making use of a 2-point control system, similar to the one used by open-close valves. They have a differential pressure of 1000 kPa and a closing pressure of 1400 kPa and the rotation angle of the valve are approximately 90 degrees.

Since Belimo control valves are key elements in the HVAC industry, they focus on these components and release outstanding products that are preferred by professional technicians, contractors, HVAC wholesalers and home users. If you intend on buying a separate valve, make sure you get the right Belimo valve actuator with it (although they usually sell both components at once). Also make sure your pipe fitting is right, so you don’t go home with the valve only to notice that it simply doesn’t fit.
