Stainless steel to clip welding hard seal butterfly valve, to clip welding hard seal butterfly valve, hard seal butterfly valve

Stainless steel pair clamp welded hard seal butterfly valve, sandwich-type butterfly valve in the middle, both sides of the pair welded flange, model D363H, pressure: 1.0mPA4.0mpa, diameter DN50-DN1600. Material: CF8, CF8M, CF3M stainless steel, 2205, 2507 duplex steel.

Stainless steel clip-welded hard seal butterfly valve, three eccentric design, through the butterfly plate sealing ring on the elasticity to achieve zero leakage seal, butterfly plate sealing ring and valve seat contact surface for oblique taper, produce a slight "wedge effect", make the sealing ring flexible and radial compression. Due to the uniform contact between the seat and the sealing ring and the flexibility of the sealing ring, the load on the seat is uniform, and the small torque is large.

The sealing ring on the butterfly plate can be replaced. Remove the pressing plate bolt, then remove the bad sealing ring, replace the new sealing ring, and then cover the pressing plate, and fix the bolt.

The butterfly plate sealing ring is made of stainless steel sheet and graphite sheet layer to form a multi-level sealing ring, this multi-level sealing ring can avoid the sealing occlusion caused by thermal expansion, and effectively prevent the small solids in the medium from damaging the sealing surface.

Stainless steel pair clamp hard seal butterfly valve has been widely used in many fields because of its unique structure and material characteristics. The following are the main application areas:

Metallurgy, electric power, petroleum and chemical industry: stainless steel clamp hard sealing butterfly valve is suitable for corrosive medium pipeline system, such as D373W-16P stainless steel clamp hard sealing butterfly valve, with high pressure resistance, corrosion resistance and wear resistance characteristics 4.

Urban architecture and public works: suitable for fire control system, water supply and drainage system, HVAC system and other scenarios, suitable for real estate, municipal, fire control, water and other industries customer groups 2.

Environmental protection and sewage treatment: Due to its corrosion resistance and sealing properties, it is suitable for the environment of treating corrosive media 23.

Food and pharmaceutical industry: some products meet the GB/T17219 standard for drinking water, which is suitable for industries with higher hygiene requirements.

Industrial manufacturing: suitable for the occasion of frequent operation and regulation of flow, its simple operation, fast opening and closing characteristics make it an ideal choice 3.

Power energy: suitable for high temperature, high pressure and corrosion resistant environment, such as power station valves
