2PC Ball Valve 904L

Description

904L (00Cr20Ni25Mo4.5Cu) is a high-alloy stainless steel engineered for severe chemical service where standard 316L would fail:

• Stress Corrosion Cracking (SCC) Defense: The high nickel concentration (approx. 25%) provides a robust barrier against SCC, maintaining structural integrity in volatile industrial settings.
• Superior Sulfuric Acid Protection: The specific addition of Copper grants this valve outstanding resistance to sulfuric acid across a wide range of concentrations and temperatures.
• Pitting & Crevice Immunity: High molybdenum and nickel content ensure the valve remains stable and leak-proof in high-chloride environments and brackish water.

Features

• Two-Piece (2PC) Body Design: The two-body construction strikes the perfect balance between structural rigidity and ease of maintenance. It allows for straightforward disassembly and seal replacement compared to one-piece models.
• Quarter-Turn Operation: Fast, 90-degree actuation provides immediate shut-off and clear visual indication of the valve position (open/closed).
• Full Bore Flow: Designed with a full-bore internal diameter, this valve offers minimal flow resistance and negligible pressure drop, ensuring maximum system efficiency.
• Precision-Engineered Ball: The spherical ball is precision-ground and polished to ensure smooth operation and a perfect seal against PTFE or reinforced seats.
• Blow-out Proof Stem: Engineered for safety, the stem is designed to remain secure within the valve body even under extreme pressure spikes.

Specifications

Applications

• Chemical Manufacturing: Production and transport of concentrated sulfuric, phosphoric, and acetic acids.
• Petrochemical Refining: High-chloride cooling water systems and aggressive catalyst management.
• Pharmaceutical & Food: High-purity acid handling where material integrity is critical to prevent batch contamination.
• Pollution Control: Flue gas desulfurization (FGD) systems where high-acid slurries are common.
