J23W-400P 304 Stainless Steel Globe Valve, Needle Valve (High-Temperature & High-Pressure, External Thread, Welded, 316L)

Product Overview

The YJZQ/KHB series stainless steel high-pressure ball valve is a high-performance fluid control device specially designed for harsh working conditions. Adopting high-quality stainless steel materials and integrated with precision manufacturing processes, this product can achieve reliable shut-off under high-pressure, high-temperature, and corrosive environments. It is widely used in key pipeline systems of petroleum, chemical, electric power, energy and other industries.

Core Product Advantages

1. Excellent Material Performance

• 304 Stainless Steel: A general-purpose austenitic stainless steel with excellent acid and alkali corrosion resistance, suitable for most corrosive media.
• 316L Stainless Steel: An ultra-low carbon molybdenum-containing steel with stronger resistance to pitting corrosion and intergranular corrosion, suitable for chloride environments.
• Material Certification: Material certification is provided, complying with ASTM A351/A182 standards.

2. High-Pressure Sealing System

• The ball surface undergoes hardening treatment (HRC ≥ 60), featuring excellent wear and erosion resistance.
• Bidirectional sealing design enables zero leakage under both forward and reverse pressures.
• Fire-safe and anti-static structure (complying with API 607/6FA standards).

3. Flexible Connection Methods

• Internal Thread Connection: After installation, the outer wall of the pipeline is smooth with a compact structure.
• External Thread Connection: High connection strength and excellent anti-vibration performance.
• Supports international standard threads such as NPT, G, and BSP.
