manual butterfly valve-Ningjin Thriveon Valve Co., Ltd.|Reliable Fluid Control, Cost-Effective Solution

Manual butterfly valves are essential components in fluid control systems, offering a reliable and cost-effective solution for various industrial applications. This article provides an in-depth analysis of the features, advantages, technical specifications, and applications of manual butterfly valves, along with insights into the company behind the product, Ningjin Thriveon Valve Co., Ltd.

What is a Manual Butterfly Valve?

A manual butterfly valve is a type of quarter-turn valve that uses a disc to control the flow of fluids. Unlike pneumatic actuator butterfly valves, which rely on air pressure for operation, manual butterfly valves are hand-operated. This includes lever-operated and gear-operated variants, making them ideal for applications where simplicity and ease of use are prioritized. Learn more about manual butterfly valves.

Key Features and Advantages

Manual butterfly valves are renowned for their simple structure, lightweight design, and cost-effectiveness. These valves are particularly suitable for environments where manual control is sufficient, eliminating the need for complex actuation systems. Key advantages include:

• Easy Installation: Their compact design allows for straightforward installation without requiring specialized tools.
• Reliable Performance: Constructed with durable materials like stainless steel and ductile cast iron, these valves ensure long-term durability.
• Space Efficiency: The small footprint of manual butterfly valves makes them ideal for applications with limited space.

Technical Specifications

The following table summarizes the technical specifications of manual butterfly valves, highlighting their material compatibility, pressure ratings, and standards compliance:

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

Pressure Ratings: Manual butterfly valves are available in various pressure classes, including CLASS 125/150, PN10/16/25, and 5K/10K/16K. These ratings ensure compatibility with a wide range of industrial systems.

Standards Compliance: These valves adhere to international standards such as API 609, BS5155, MSS SP-67/68, and EN593, ensuring quality and interoperability across global markets.

Installation Guidelines

Proper installation is critical to the performance and longevity of manual butterfly valves. Follow these steps for optimal results:

1. Flange Alignment: Space out the flanges to allow the valve to pass easily. Ensure the disc is in a half-opened position during installation.
2. Gasket Placement: Avoid fitting gaskets between flanges to prevent misalignment.
3. Bolt Tightening: Insert all bolts with the disc in a half-opened position. Do not tighten the nuts immediately.
4. Final Adjustment: Fully open the valve to verify pipeline alignment, then tighten the nuts securely.

Manual vs. Pneumatic Actuated Butterfly Valves

While both manual and pneumatic actuated butterfly valves serve similar purposes, their differences lie in operation and application. Manual butterfly valves are preferred for low-demand scenarios due to their simplicity and lower cost. In contrast, pneumatic actuated valves offer automated control, making them suitable for high-precision or hazardous environments. Explore gear-operated butterfly valves.

Applications in Various Industries

Manual butterfly valves are widely used in industries such as:

• Water Treatment: For regulating flow in municipal water systems.
• Chemical Processing: To manage corrosive fluids with appropriate material choices.
• HVAC Systems: For air and coolant flow control in buildings.
• Power Generation: In cooling and steam systems.
