Electric stop valve J961Y-63 for Sipat power Power Plant｜YOYIK
Product Introduction

The J961Y-63 Electric Stop Valve is a high-reliability medium-high pressure electrically operated cutoff device specially designed for large thermal power plant pipeline systems, integrating a precision forged valve body and a high-efficiency multi-turn electric actuator. Compliant with PN63 pressure class (maximum working pressure ≤6.3MPa), it is made of high-quality carbon steel (marked by model suffix Y) with precision-machined sealing surfaces, which provides excellent structural strength, pressure-bearing capacity and wear resistance, specially customized to meet the operational requirements of Sipat power Power Plant and other medium-high pressure thermal power generation facilities. Its optimized straight-through flow passage design minimizes pressure loss and flow resistance, while ensuring rapid and leak-tight isolation of medium-high pressure media in critical pipeline systems, fully complying with the relevant manufacturing standards for power plant valves.

This electric stop valve is mainly applied in the medium-high pressure pipeline networks of Sipat power Power Plant, capable of effectively controlling and isolating media such as saturated steam, high-pressure boiler feedwater and industrial oil. Operating stably at a maximum working temperature of 425℃ (matching PN63 pressure class), it is widely used in power plant boiler auxiliary systems, turbine cooling circuits and key instrument control pipelines, which is a key equipment to ensure the safe and stable operation of power generation units. It provides reliable guarantee for the safe, stable and efficient operation of power generation equipment by achieving precise on-off control and adapting to the medium-high pressure working environment of the power plant, and can withstand 1.1 times the rated working pressure without leakage in the closed state.

Product Features & Operation Points

- High-quality carbon steel valve body (model suffix Y) features excellent structural rigidity, pressure-bearing performance and cost-effectiveness, adapting to the medium-high pressure pipeline environment of Sipat power Power Plant, ensuring long-term stable operation without deformation or leakage, and suitable for the working conditions of saturated steam and high-temperature oil media.

- Compliant with PN63 pressure class (≤6.3MPa) and manufactured in strict accordance with GBT 12235, API 600 and relevant national standards for power plant valves, the valve undergoes rigorous hydrostatic testing (test pressure 9.45MPa, 1.5 times the rated pressure) and low-pressure sealing testing (test pressure 0.6MPa) to completely eliminate leakage risks under rated and extreme working pressures, meeting the strict safety requirements of power plants.

- Equipped with a high-efficiency multi-turn electric actuator, it supports remote and local dual-control modes, with real-time position feedback, overload protection and fault prompt functions, reducing manual operation intensity and improving the accuracy and efficiency of pipeline control in Sipat power Power Plant systems, realizing automatic control of the pipeline介质 flow.

- Adopts a precision-ground metal-to-metal hard sealing structure, combined with advanced surface polishing treatment, achieving excellent sealing performance under medium-high pressure and high temperature conditions, reducing maintenance frequency and operation and maintenance costs, and ensuring that the valve can maintain good sealing performance during long-term frequent on-off operations.

- Integral forged valve body structure (without any welding seams) eliminates internal defects such as pores, cracks and inclusions, enhances the overall structural strength and impact resistance, adapts to the frequent pressure fluctuation scenarios in the medium-high pressure pipelines of Sipat power Power Plant, and is compatible with 25MW-600MW unit pipeline systems.
