Characteristics
The groove-type (clamped) connected valve is new connection valves designed and manufactured based on
similar advanced products from USA and Germany. It features rapid, simple, secure, reliable installation,
without being limited by installation sites. It convenient for maintenance of pipelines and valves. It provides
isolation, soundproofing, accommodating certain angles to overcome deviations in pipeline connections with
different axes. It addresses issues like thermal expansion and contraction due to temperature differences.
D381X-16Q & D81X-16Q utilized in various pipeline engineering applications. They include fluid
transmission pipelines for water supply and drainage, firefighting, air conditioning, gas, petroleum,
chemical, water treatment, municipal projects, shipbuilding. It serves to control flow of fluids.
