As the annual heating season approaches, NSEN will enter a busy phase in the summer. In preparation for this year’s heating season, our customers have placed several orders in succession. It is expected that 800pcs of butterfly valves for heating will be produced this year. Therefore, our company stock a lot of butt welding type, and flange butterfly valve casting.

Below we will briefly introduce the butterfly valves used for district heating;

We all know that the heating medium mainly takes high-temperature steam and hot water, so the soft-sealing butterfly valve should be excluded when the option is selected, and the metal-sealed butterfly valve must be selected. According to the sealing, we are mainly divided into two types, the first type is a laminated sealing butterfly valve, and the second type is a solid metal sealing butterfly valve. These two types of sealing structures need to be determined according to the temperature and flow rate of the working medium.

According to the connection method, the main requirements are butt welding and flange type. Currently NSEN can provide connection standards:

GOST 33259-2015, GOST 12815, EN1092-1, ASME B 16.5/B16.47
