PN64 (6. 4MPa) Medium High Pressure Stop Valve J61Y-64P | YOYIK
Product Introduction
The J61Y-64P Stop Valve is a manual lift globe valve featuring an integral forged high-strength structure, with premium alloy steel (compatible with PN64 pressure class and suffix P material standard) as its core body material. It meets national industrial standards for nominal pressure PN64, precisely equivalent to 6. 4MPa under ambient temperature, and is equipped with a finely machined manual lifting stem. Specifically engineered for medium-high pressure pipeline systems in thermal power plants, it is ideal for scenarios requiring reliable pressure-bearing capacity, superior high-temperature resistance and long-term stable operation.
Highly adaptable to the operating conditions of thermal power plant pipelines, it is suitable for media including high-temperature superheated steam, high-pressure feedwater and light oil. With a maximum operating temperature of 425℃ and pressure of 6. 4MPa (fully consistent with PN64 rating), it provides stable and accurate on-off control for medium-high pressure pipelines and auxiliary instrument loops, fully complying with the strict operational standards of thermal power plant medium-high pressure pipeline systems. It is applicable to projects such as Kamalanga Power Plant.
Company Profile
YOYIK is a professional manufacturer specializing in industrial stop valves and power plant equipment, committed to serving the global energy industry and thermal power generation projects. We focus on the R&D, design and production of high-standard stop valves that meet international and national industrial standards, including the J61Y-64P model which is perfectly matched with PN64 pressure class and corresponding alloy steel material (suffix P specification). Supported by a rigorous quality management system and a global after-sales service network, we can fully satisfy customers' high-standard requirements for medium-high pressure stop valve products in thermal power plants.
Product Features & Operation Points
- PN64 (6. 4MPa) Pressure Class Conformance: Compliant with national industrial standards for PN64 nominal pressure, the valve provides dependable medium-high pressure bearing capacity, able to resist the impact of high-pressure media in thermal power plant pipelines while maintaining leak-free and stable operation, perfectly adapting to the medium-high pressure working environment of thermal power generation.
- Exceptional Shut-Off Dependability: Adopting a precision-ground conical hard seal combined with surface hardening technology, the valve achieves tight and long-lasting media shut-off without leakage. This key performance guarantees the safety and stability of medium-high pressure pipeline systems, avoids operational risks caused by media leakage, and supports continuous power generation.
- Premium Alloy Steel with Suffix P: Made of high-quality alloy steel that matches PN64 pressure class and meets suffix P material requirements, the valve possesses excellent high-temperature resistance (up to 425℃), as well as strong mechanical strength, wear resistance and corrosion resistance, ensuring long-term reliable service in medium-high pressure pipelines of thermal power plants.
- Stable Sealing & Effortless Operation: Equipped with metal-to-metal hard seating and high-temperature resistant flexible graphite packing, the valve maintains stable sealing performance under medium-high pressure and high-temperature conditions, preventing media leakage and impurity ingress. Its precision-threaded manual stem allows for smooth and labor-saving operation, enabling accurate on-off control of pipeline systems.
- International Standard Compliance & Easy Maintenance: Strictly manufactured in line with API 598, HG/T 20592 and other international and national standards, the valve is fully compatible with global large-scale thermal power plant equipment. Its top-mounted design facilitates on-site inspection and maintenance, effectively reducing equipment downtime and maintenance costs.
