Understanding Manual Butterfly Valves

A manual butterfly valve is a type of quarter-turn valve that uses a disc to control flow. It is operated manually via a lever, gear, or handwheel, making it a simple and robust solution for various industrial applications. Unlike pneumatic or electric actuators, manual valves eliminate the need for external power sources, reducing complexity and maintenance costs. For a detailed comparison, refer to the FAQ section.

Key Features and Advantages

1. Simple Structure and Ease of Installation

Manual butterfly valves are designed with a simple structure, making them easy to install and maintain. Their compact design ensures minimal space requirements, while the lever or gear operation allows for straightforward manual control. According to the National Institute of Standards and Technology (NIST), such designs align with industry standards for reliability and efficiency.

2. Durable Materials

The valve's construction uses high-quality materials to ensure longevity and performance. Common materials include:

• Body: Grey Cast Iron, Ductile Cast Iron, Stainless Steel 304/316, Carbon Steel
• Disc: Ductile Cast Iron (Nickel-plated or Nylon coated), Stainless Steel 304/316, Aluminum Bronze
• Stem: Stainless Steel 410/416/304/316
• Seat: EPDM, BUNA-N, PTFE, Viton, Hypalon, Neoprene, Metal Seated

These materials are selected to withstand harsh environments, ensuring the valve's durability under varying pressure and temperature conditions.

3. Versatile Pressure Ratings

Manual butterfly valves are available in multiple pressure ratings, including:

• CLASS 125/150
• PN10/16/25
• 5K/10K/16K

This versatility makes them suitable for a wide range of applications, from low-pressure systems to high-performance industrial settings.

Technical Specifications

Applications and Industry Use Cases

Manual butterfly valves are widely used in industries where reliable flow control is essential. Key applications include:

• Water Treatment: Regulating water flow in municipal and industrial systems.
• Chemical Processing: Managing corrosive fluids in chemical plants.
• HVAC Systems: Controlling air and coolant flow in heating and cooling systems.
• Oil and Gas: Isolating pipelines in low-pressure environments.
• Power Generation: Managing coolant and steam flow in power plants.

The valve's compliance with international standards such as NIST ensures its suitability for critical applications. For more details on standards, refer to the product specifications.

Installation and Maintenance Guidelines

Proper installation is crucial for the optimal performance of manual butterfly valves. Follow these steps:

1. Flange Preparation: Ensure flanges are spaced to allow the valve to pass easily, with the disc in a half-opened position.
2. Gasket Installation: Avoid fitting gaskets between flanges to prevent misalignment.
3. Bolt Placement: Insert all bolts with the disc in a half-opened position, but do not tighten the nuts yet.
4. Final Adjustment: Open the valve fully to verify pipeline alignment, then tighten the nuts securely.

Regular maintenance, including lubrication of the stem and inspection of the seat, ensures long-term reliability. For detailed instructions, consult the installation guide.
