Product Introduction
Company Profile
Product Features & Operation Points
- High-pressure optimized design with a nominal pressure of PN320 (32.0MPa), precisely matching the operational demands of key three-way pipelines in power stations, metallurgy, chemical industry and mining industries, effectively realizing reliable medium diversion, confluence and quick cut-off while preventing medium leakage, eliminating safety hazards in harsh working environments, and adapting to the special working conditions of various industries.
- Scientific three-way flow channel structure combined with quick opening design, greatly reducing medium flow resistance, ensuring smooth medium diversion and confluence, mitigating erosion damage to the valve seat and clack caused by high-velocity media, and realizing ultra-fast opening response, ensuring long-term stable and reliable diversion, confluence and cut-off performance in industrial three-way pipeline systems, which is consistent with the structural advantages of three-way pneumatic quick opening valves.
- Superior material performance: The valve body of J661Y-320 is made of high-quality forged alloy steel (optimized for high-temperature creep resistance, sealing performance and quick opening response), combined with wear-resistant alloy overlay on the valve core and seat, offering excellent pressure-bearing capacity, ultra-high temperature resistance, wear resistance and corrosion resistance, which is perfectly adapted to the harsh working conditions of power stations, metallurgy, chemical industry and mining industry pipeline systems, and can be customized according to special media requirements.
- Adopts high-efficiency pneumatic actuator operation and metal-to-metal seating precision structure; the valve clack and seat are precision ground to achieve tight sealing effect, while the pneumatic control ensures quick response, stable operation and easy remote control, realizing ultra-fast opening and precise flow control, suitable for automatic control scenarios in industrial three-way pipelines. The valve stem is treated with special surface treatment to reduce friction, ensuring no external leakage during long-term operation and facilitating on-site operation, maintenance and debugging without removing the valve from the pipeline, matching YOYIK's professional service concept.
- Strictly complies with international industry standards such as API 623, ASME B16.34 and GBT 12224, and all products pass strict performance testing, while supporting customized design and production according to customer specific needs, ensuring excellent interchangeability with existing industrial equipment and simplifying on-site maintenance and spare part replacement processes. Backed by YOYIK's one-stop solution capability, it fully meets the special requirements of different industries and working conditions.
