Product Introduction
Company Profile
Product Features & Operation Points
- Designed with nominal pressure of 2000SPL (equivalent to PN320, 32. 0MPa), it matches the pressure requirements of Kolaghat Power Plant's main steam pipeline systems, stably bears ultra-high medium pressure and avoids leakage risks, meeting ultra-high-pressure operation standards of large thermal power plant main steam systems, consistent with YOYIK's high-standard product positioning.
- Adopts wedge rigid gate plate structure and manual operation (marked by model Z564), realizes precise on-off control of media in power plant ultra-high-pressure main steam pipelines, effectively cuts off or connects ultra-high-temperature, ultra-high-pressure main steam and oil media, suitable for large-caliber main steam pipeline installation of Kolaghat Power Plant, manufactured with YOYIK's advanced production equipment.
- Valve body is made of SA-182 F91 alloy steel (marked by suffix Y and SA-182 F91), featuring excellent ultra-high-temperature resistance, corrosion resistance, wear resistance and ultra-high-pressure-bearing capacity, adapting to the harsh ultra-high-temperature and high-pressure working environment of Kolaghat Power Plant's main steam pipelines, and ensuring long-term stable operation under main steam working conditions.
- Equipped with manual operation mode, it is simple in structure, reliable in operation and easy to maintain, with stable force transmission, facilitating on-site precise operation and daily inspection by operators, reducing daily operation and maintenance difficulty of Kolaghat Power Plant's main steam equipment, and strictly inspected by YOYIK's quality management system.
- Complies with GBT 12234, API and ASME international standards, manufactured with YOYIK's advanced production equipment and strict quality management system, with complete testing procedures, convenient for later maintenance and replacement, matching global power plant main steam equipment accessory standards, consistent with YOYIK's product quality commitment for key engineering projects.
