Rotary disc valves series 30/31
An economical solution for general industrial applications in water and heat supply systems, ventilation and air conditioning, fire extinguishing.
The design of the gate allows for use both to block the flow and to regulate its flow (shut-off valves).
Depending on the materials used, it is possible to operate the valves on liquid, viscous, dry and gaseous media, abrasive and aggressive media, in a wide range of temperature and pressure modes, for vacuum.
