1. Rapid Assembly: Socket Fusion Fittings utilize a hot-melt socket welding process. Welding is completed simply by inserting the pipe into the sleeve and heating for tens of seconds. The overall operation time is significantly shorter than the minutes or even hours required for traditional arc or gas welding. 2. Low O...

Select materials based on its corrosiveness, viscosity, and temperature range. PPR is suitable for hot water, PVC for acid and alkali media, and PE-RT for low-temper...
View MoreWhat are Butterfly Valves PPN?
1. Definition and Function
Butterfly Valves PPN (Polypropylene-Nylon) is a butterfly valve manufactured using a polypropylene-nylon composite material (PPN). This material combines the corrosion resistance of polypropylene with the high strength of nylon, allowing the valve body to maintain good sealing performance and structural strength even in environments with strong acids, strong alkalis, and organic solvents.
2. Technical Advantages
High Chemical Resistance: PPN material exhibits extremely low permeability to most chemical media (such as sulfuric acid, hydrochloric acid, hydrofluoric acid, etc.), making it suitable for highly corrosive industries such as chemical and pharmaceutical manufacturing.
Lightweight and High-Strength: Compared to metal valve bodies, PPN butterfly valves are lighter, facilitating handling and installation, while the nylon reinforcement layer provides excellent impact resistance and abrasion resistance.
Cryogenic Adaptability: Maintains stable mechanical properties over a wide temperature range of -40°C to 120°C, meeting the requirements of aerospace and cryogenic refrigeration systems.
3. Application Scenarios
Pipelining systems for solar photovoltaic modules
Pure water and acid washing circuits in semiconductor manufacturing
Transportation of corrosive media in environmental protection and biochemical treatment
Differences from Traditional Metal Butterfly Valves
While traditional metal butterfly valves can withstand high pressure, they are prone to corrosion in corrosive environments, requiring frequent maintenance; Butterfly Valves PPN, through its inherent corrosion resistance, significantly reduces maintenance costs and downtime.
Application Value of Butterfly Valves PPN in Key Industries
1. Solar Photovoltaic Industry
Photovoltaic support piping systems using PPN butterfly valves can withstand long-term exposure to ultraviolet radiation and acid rain, extending system lifespan.
2. Semiconductor Manufacturing
In ultrapure water circulation and chemical gas transportation, the low leakage characteristics of PPN butterfly valves ensure the cleanliness of the production environment and reduce the risk of particulate contamination.
3. Chemical and Pharmaceutical Industries
The resistance to strong acids, strong alkalis, and organic solvents makes it the preferred valve for chemical reactors and pharmaceutical production lines, significantly reducing maintenance costs.
4. Environmental Protection and Biochemical Treatment
In wastewater treatment and bioreactors, the corrosion resistance and high-temperature resistance of PPN butterfly valves ensure long-term stable operation and improve treatment efficiency.
