Electric Stop Valve J961Y-P54.540V for Satpura power｜YOYIK

Electric Stop Valve J961Y-P54.540V for Satpura power Power Plant｜YOYIK
Product Introduction

The J961Y-P54.540V Electric Stop Valve is a medium-high pressure electrically driven isolation valve combining a solid forged valve body and a high-efficiency multi-turn electric actuator, specifically designed for thermal power generation scenarios. Boasting PN40MPa nominal pressure (extracted from the model’s 40 marking) and a P54.5 alloy steel body, it is tailored for medium-high pressure pipeline networks in power generation facilities, complying with international standards such as GBT 12235, API 600 and ASME B16.34.

Custom-built for Satpura power Power Plant’s medium-high pressure systems, this valve manages and isolates saturated steam, high-pressure boiler feedwater and high-temperature industrial oils, operating steadily at a maximum temperature of 540℃ and a working pressure not exceeding 40MPa. It fits perfectly into boiler auxiliary systems, turbine cooling circuits and key instrument loops in thermal power plants, ensuring reliable media isolation to support stable power generation operations.

Company Profile

Headquartered in Deyang, YOYIK stands as a global top-tier manufacturer of industrial valves and power plant spare parts, focusing on the research, development and production of high-reliability electric stop valves. It offers customized products and technical solutions for power, chemical and steel industries, supported by a strict quality control system and a worldwide service network.

Product Features & Operation Points

- Engineered to PN40MPa nominal pressure (≤40MPa, recognized from model 40) and conforming to GBT 12235, API 600 and ASME B16.34 standards, it undergoes stringent hydrostatic testing at 60MPa and low-pressure sealing testing at 0.6MPa, effectively avoiding leakage issues and adapting to Satpura power Power Plant’s medium-high pressure working conditions.

- Equipped with an advanced multi-turn electric actuator, it enables both remote and on-site operation modes, with functions including real-time position feedback, overload protection and fault alarm, which improves the stability and accuracy of pipeline control in power generation facilities.

- Crafted with a P54.5 alloy steel valve body, the sealing surface features hard alloy overlay, and auxiliary components are made of austenitic stainless steel (marked by suffix V), providing excellent high-temperature resistance and corrosion resistance to handle the complex environment of medium-high pressure pipelines in thermal power plants.

- Utilizing a precision-ground metal-to-metal hard sealing structure and valve stem nitriding technology, it achieves reliable sealing performance under medium-high temperature and pressure conditions, reducing equipment maintenance times and operational costs for power plants.

- The solid forged valve body (without any welding seams) eliminates internal defects such as pores and cracks, enhancing overall structural rigidity and impact resistance, and it is compatible with 100MW-600MW unit pipelines in various thermal power plants.
