Electric Stop Valve J961Y-P54.5150V for Pacitan power Power Plant｜YOYIK
Product Introduction

The J961Y-P54.5150V Electric Stop Valve is an electrically operated cutoff device with a precision forged valve body and multi-turn electric actuator, designed for thermal power plants with PN150MPa nominal pressure (decoded from model 150) and P54.5 alloy steel body. It is mainly used in high-pressure pipeline systems of power generation facilities, complying with GBT 12235, API 600 and ASME B16.34 international standards.

Applied in Pacitan power Power Plant’s high-pressure pipelines, this valve controls superheated steam, high-pressure boiler feedwater and industrial oil, operating stably at a maximum temperature of 570℃ and pressure of ≤150MPa. It perfectly matches the working conditions of thermal power plant boiler systems, turbine circuits and instrument loops, ensuring safe isolation of media in power generation units.

Company Profile

YOYIK is a leading global manufacturer of industrial valves and power plant equipment based in Deyang, focusing on the R&D and production of high-demand electric stop valves, providing customized spare parts for power plants, chemical and steel industries with a complete quality management system and global service network.

Product Features & Operation Points

- Compliant with PN150MPa nominal pressure (≤150MPa, decoded from model 150) and international standards (GBT 12235, API 600, ASME B16.34), undergoing rigorous hydrostatic (225MPa) and low-pressure sealing (0.6MPa) tests to eliminate leakage risks, adapting to high-pressure working conditions of Pacitan power Power Plant.

- Equipped with intelligent multi-turn electric actuator, supporting remote and local dual-control modes with real-time position feedback and overload protection, improving the efficiency and accuracy of pipeline control in power generation facilities.

- Adopts P54.5 alloy steel forged body with hard alloy surfacing and austenitic stainless steel auxiliary parts (suffix V), featuring excellent high-temperature resistance and corrosion resistance, suitable for harsh environments of thermal power plant high-pressure pipelines.

- Adopts precision metal-to-metal hard sealing structure and valve stem nitriding treatment, ensuring tight sealing performance under high-temperature and high-pressure conditions, reducing maintenance frequency and operation costs for power plant equipment.

- Integral forged body structure (no welding seams) eliminates internal defects such as pores and cracks, enhancing structural strength and impact resistance, compatible with 300MW-1000MW unit pipelines of thermal power plants.

Applications

- Boiler main steam pipeline of thermal power plants

- Turbine high-pressure feedwater cutoff pipeline in power generation facilities
