The Tomoe 700G gear operated butterfly valve is a high-quality industrial butterfly valve from Tomoe, Japan. It is designed with a gearbox handwheel mechanism for smooth operation, precise flow control, and long-term durability.

This valve is an ideal solution for water supply, drainage, HVAC, fire protection, and large industrial piping systems that require high sealing performance and stable operation.

Technical Specifications of Tomoe 700G Butterfly Valve

What is the Tomoe 700G Gear Operated Butterfly Valve?

The Tomoe 700G butterfly valve is a wafer-type industrial butterfly valve equipped with a gear operated handwheel. It controls flow by rotating the valve disc from 0° to 90°, allowing both shut-off and throttling functions.

Compared with lever-operated butterfly valves, the Tomoe 700G offers several advantages:

• Easier operation on large pipe sizes
• More precise opening angle adjustment
• Slower, smoother closing to reduce water hammer
• Improved operational safety

This valve is especially suitable for large pipelines from DN100 and above, where lever operation becomes difficult.

Key Advantages of Tomoe 700G Gear Operated Butterfly Valve

1. Easy operation for large diameter pipelines

Thanks to the gearbox reduction mechanism, operators can open or close the valve smoothly with minimal effort, even on large sizes.

2. Compact wafer design for easy installation

The wafer connection design provides:

• Space-saving installation
• Easy mounting between flanges
• Lower installation costs

3. Excellent sealing performance

Tomoe butterfly valves are known for:

• High sealing efficiency
• Stable opening and closing
• Reduced leakage risk

4. Durable materials with good corrosion resistance

Depending on the application, users can choose:

• Stainless steel disc: suitable for clean or corrosive environments
• Stainless-clad cast iron disc: cost-effective while maintaining durability

  

   

Structure of Tomoe 700G Butterfly Valve

Main components include:

Valve Body

• Made of cast iron
• Designed for JIS 10K pressure rating
• Strong and durable

Valve Disc

• Controls flow directly
• High wear resistance

Valve Stem

• Connects disc to gearbox
• Provides stable torque transmission

Working Principle of Tomoe 700G Butterfly Valve

The valve works by rotating the disc around its shaft:

• 0°: fully closed
• 90°: fully open
• Intermediate angles: flow regulation

The gearbox handwheel allows:

• Smooth gradual operation
• Better flow control
• Reduced hydraulic shock
