Product Introduction
Company Profile
Product Features & Operation Points
- Designed with PN5. 5MPa nominal pressure (5. 5MPa, identified from model 55) and compliant with GBT 12235, API 600 and ASME B16. 34 standards, it undergoes rigorous hydrostatic testing at 8. 25MPa and low-pressure sealing testing at 0. 6MPa, effectively eliminating leakage risks for NTPL power Power Plant's medium-pressure operating conditions, reflecting YOYIK's excellent quality and good market reputation.
- Equipped with a multi-turn electric actuator, it supports remote and on-site dual-control modes with real-time position feedback and overload protection, improving control accuracy and operational efficiency of pipeline systems in power generation facilities, embodying YOYIK's leading technological position and excellent management philosophy.
- Constructed with P55. 5 alloy steel forged body (marked by suffix V), the sealing surface adopts hard alloy overlay technology, and auxiliary components are high-quality alloy steel, providing excellent high-temperature resistance and corrosion resistance for complex medium-pressure pipeline environments, ensuring stable product performance and echoing YOYIK's excellent quality positioning.
- Adopts precision metal-to-metal hard sealing structure and valve stem nitriding treatment, ensuring tight sealing performance under medium temperature and pressure, reducing maintenance frequency and operational costs for power plants, matching YOYIK's diversified product supply and cost-effective positioning.
- Integral forged valve body (no welding seams) eliminates internal defects such as pores and cracks, enhancing structural strength and impact resistance, compatible with 100MW-400MW unit pipelines in power generation facilities, adapting to the diverse industrial field needs served by YOYIK's diversified product line.
