Product Overview
Introducing the industrial-grade Stainless Steel Globe Valve from Wenzhou Safety Stainless Steel Co., Ltd., a superior fluid control solution crafted for the most demanding industrial sectors. This high-performing valve is a staple across various industries, such as petroleum, chemical, power generation, and pharmaceuticals. Its stainless steel construction with welded connections provides unmatched sealing capabilities, outstanding corrosion resistance, and supreme durability under high-pressure and extreme temperature conditions, ensuring precise flow regulation or complete shutoff for unparalleled system safety and stability.
Structure & Materials
1.
Valve Body Material
- The valve's main body is meticulously crafted from premium-grade stainless steel, including 304, 316, and 316L variants. This construction provides excellent corrosion resistance, making it impeccably suited for handling acidic, alkaline, and high-purity media with ease.
- For environments that present extreme conditions, specialized materials like duplex steel or the highly resilient Hastelloy® are available to ensure optimal performance and longevity.
2. Welded Connections
- Our precise butt-weld (BW) ends adhere to ASME B16.25 standards, guaranteeing a seamless, leak-proof integration with existing pipeline systems. This makes it ideal for managing high-pressure and hazardous fluid environments with confidence.
3.Sealing Design
- Featuring hard-faced sealing surfaces, such as Stellite®-coated discs and seats, this valve is engineered for exceptional wear and erosion resistance, significantly extending its service life in demanding applications.
- The packing chamber employs advanced flexible graphite or PTFE seals, expertly preventing stem leakage even under the rigors of high temperatures and pressures.
4. Actuation Options
- Manual operation is enhanced through an ergonomic handwheel or gearbox, designed for low-torque and precision positioning with an intuitive position indicator.
- For automated systems, this valve is compatible with both electric and pneumatic actuators, facilitating seamless remote control and integration into complex systems.
Technical Specifications
- Nominal Diameter**: DN15 ~ DN100 (1/2"~4")
- Pressure: PN16
- Temperature Range: -196°C (cryogenic) to +550°C (high-temperature steam)
- Media Compatibility: Water, steam, oils, corrosive chemicals, liquefied gases, etc.

Key Advantages
Extreme Condition Resilience: Our valve's cryogenic treatment and high-temperature hardening processes make it an ideal choice for challenging LNG and steam applications, standing up to the most rigorous environmental demands.
Zero-Leakage Assurance: Built with a dual-seal design incorporating both metal and soft sealing, this valve undergoes stringent testing per API 598 standards, ensuring complete reliability with toxic and flammable media.
Longevity-Optimized: Engineered with an anti-blowout stem, self-lubricating bearings, and designed for minimal maintenance, this valve offers long-lasting performance and reduced operational downtime.
Typical Applications
-Petrochemical: An essential component for reactor inlet/outlet lines and high-pressure ethylene pipelines, providing secure and efficient fluid management.
-Energy Sector: Perfectly adapted for nuclear steam systems and thermal power plant feedwater control, ensuring stability and safety in critical energy applications.
-Fine Chemicals: Expertly handling corrosive acid/alkali transfer and supporting pharmaceutical-grade purity systems with absolute precision.
-LNG Infrastructure: Designed to excel in cryogenic liquefied natural gas storage and transportation, this valve ensures safe and effective handling of LNG applications.
Installation & Maintenance Guidelines
- Ensure media flow direction aligns with the valve arrow marking ('low-in, high-out') to prevent seal compromise and maintain optimal performance.
- For enhanced durability, post-weld stress relief and argon arc root welding are recommended practices to avoid intergranular corrosion.
- Regular inspection of stem packing and consistent tightening of gland bolts are advised to maintain reliability and system integrity.
