In chemical, pharmaceutical, food processing, and biotechnology industries, crystallization inside storage tanks is a common and challenging problem. When process media solidifies at the tank bottom, traditional valves often become blocked or locked by crystal buildup, resulting in leakage, shutdowns, and expensive maintenance.

To solve this industry-wide problem, Fujian JST Valve Manufacturing Co., Ltd. developed the innovative Ice Breaking Tank Bottom Valve, a new-generation industrial valve specially designed for anti-crystallization and anti-blockage applications.

With nearly 33 years of experience in severe service valve engineering, JST Valve provides customized valve solutions for corrosive, abrasive, and crystallizing media systems.

What Is an Ice Breaking Tank Bottom Valve?

The Ice Breaking Tank Bottom Valve is an advanced industrial valve designed to prevent valve jamming caused by crystal solidification inside storage tanks and process vessels.

Unlike traditional tank bottom valves, this valve incorporates a unique mechanical ice-breaking structure that actively destroys crystal buildup around the valve core and seat during operation.

This innovative design significantly improves valve reliability and production stability in systems handling crystallizing media.

Why Traditional Tank Bottom Valves Fail

In many industrial production processes, media at the bottom of tanks can crystallize due to:

• Temperature reduction
• Long-term storage
• High-viscosity fluids
• Chemical reactions
• Slurry or residue accumulation

When crystallization occurs, the valve core and seat may become completely surrounded by hardened deposits. This causes:

• Valve locking
• High operating torque
• Seal failure
• Production shutdowns
• Frequent maintenance

Traditional tank bottom valves are often unable to solve this problem effectively.

Innovative Ice Breaking Design Mechanism

JST Valve redesigned the internal transmission structure of the tank bottom valve to provide dual-function operation.

The design includes:

• A specially engineered fork mechanism integrated into the drive shaft
• A rotating ice-breaking cutter installed above the valve core

This mechanism allows the valve to mechanically break and remove crystallized material during operation.

Working Principle of the Ice Breaking Tank Bottom Valve

During valve operation, axial force drives the transmission fork, activating the rotating ice-breaking cutter head.

The cutter head performs multiple functions:

• Breaks hardened crystal deposits
• Eliminates media solidification around the valve core
• Reduces friction caused by crystallized materials
• Prevents valve seizure and locking

This ensures smooth opening and closing operation while maintaining reliable sealing performance.

Main Advantages of the Ice Breaking Tank Bottom Valve

1. Excellent Anti-Crystallization Performance

The valve effectively prevents blockage caused by crystal buildup and solidified process media.

2. Self-Cleaning Capability

The internal rotary cutter continuously removes deposits during operation, reducing maintenance frequency.

3. Improved Production Efficiency

By preventing shutdowns and valve failure, the valve helps maintain continuous industrial production.

4. Longer Service Life

Reduced mechanical stress and lower operating friction significantly extend valve lifespan.

5. Customized Special Material Options

JST Valve offers customized materials for severe corrosive environments, including:

• Hastelloy
• Titanium
• Zirconium
• Nickel Alloy
• Super Austenitic Stainless Steel
