Insulation jackets for Frese S and PV
The insulation jackets have been specifically designed for the insulation of Frese S, and PV valves. Insulation of valves reduces the temperature in control room, boiler room or pipe tunnels - resulting in a more agreeable working temperature, reduced thermal loss and, consequently, better heat economy year after year.
Frese Manometer 2023 P
Freses digital manometer for the measurement of differential pressure in a given installation equipped with Frese valves.
The manometer features are:
- On/off
- Automatic reset
- Illuminated display
- "Out of measuring range”
- Hold function
- Hose kit incl. needles
The manometer is easily operated by means of the enclosed, detailed instructions for use.
After measuring, the actual value is compared with the min. required differential pressure across the installed flow rate cartridge.
Frese strainers
Frese strainers are particularly designed and manufactured in order to provide maximum protection of the pipeline equipment against particles and other impurities. They are necessary in all fluid, steam and non-flammable gas systems where the presence of dirt could result in high operating, maintenance and replacement costs.
The fluid enters the Frese strainer and passes into the interior of a cylindrical screen. While the fluid passes through the screen, all particles larger than the screen mesh are trapped in the screen. When the filter is removed from the strainer, it acts as a container for the accumulated impurities.
The Frese strainers can perform in both horizontal and vertical installations provided that the direction of flow, as marked on the strainer, is always respected and that the filter, for vertical pipes, is situated downwards.
Frese drain valves
Drain valves are used for filling and emptying domestic water systems, cooling systems, solar heating systems and district heating systems.
