In this article, Bao Tin Steel will guide you through the design, technical specifications, applications, latest pricing, and reliable sources for purchasing genuine Shin Yi valves.

Design and Appearance

The Shin Yi lever-operated butterfly valve features a compact and sturdy design, characteristic of the wafer-type valves. The valve body is cast from ductile iron for high durability and coated with Epoxy paint for corrosion resistance. It is available in blue and red, making it easy to identify within different systems (e.g., clean water, fire protection).

The lever is made of black-painted steel and designed as a multi-position locking lever, allowing quick one-hand operation and the ability to fix the valve at multiple opening angles – very convenient for flow regulation.

The internal disc is typically stainless steel 304 or coated cast iron, with a smooth finish, paired with black EPDM or NBR gaskets for effective sealing and minimal leakage. Two integral positioning lugs on the sides of the body assist with easy alignment during installation and enhance the structural stability of the valve.

Overall, the valve offers a robust, unified, and easy-to-install solution, particularly suitable for piping systems from DN50 to DN200, where fast operation, limited installation space, and cost-effectiveness are required.

Key Advantages of the Shin Yi Lever-Operated Butterfly Valve

The Shin Yi lever-operated butterfly valve not only meets all technical standards but also wins users over with the following practical advantages:

Quick Operation – Easy to Use

• The valve uses a quarter-turn lever mechanism, allowing full opening or closing with a light, single action. The lever features a multi-position locking design, supporting flexible flow regulation.

Compact Design – Easy Installation

• With a wafer-type connection and lightweight construction, the valve is suitable for installation in limited spaces, making it especially convenient for piping in factories, pump stations, or technical cabinets.

High Durability – Long Service Life

• The ductile iron body, paired with a stainless steel or coated cast iron disc and high-quality EPDM/NBR gasket, ensures reliable long-term operation even in humid environments or medium-pressure systems.

Excellent Sealing – Leak Prevention

• The internal sealing gasket is fully enclosed, providing tight sealing, preventing water leakage, and minimizing pressure loss in the system.

Cost-Effective Investment

• Compared to electric or gear-operated valves, the lever-operated butterfly valve is more affordable while still meeting standard operational requirements, making it an optimal choice for small to medium-sized systems.

Practical Applications

Thanks to its simple design, flexible operation, and high durability, the Shin Yi lever-operated butterfly valve is widely used across various industries. Common working environments include:

• Domestic and industrial water supply and drainage systems: pumps, water treatment plants, reservoirs, underground tanks, etc.
• Fire protection systems (PCCC)
• Wastewater treatment systems
• HVAC systems: air conditioning in high-rise buildings, factories, and shopping centers

Other Applications

• Agricultural irrigation systems
• Residential pump stations
• Civil construction and infrastructure projects

Installation Notes for Shin Yi Lever-Operated Butterfly Valve

Since the Shin Yi lever-operated butterfly valve is of the wafer-type connection, it is important to follow these guidelines during installation to ensure stable, durable operation and prevent potential issues:

• Open the valve disc about 1/4 turn before positioning it between the flanges. This prevents deformation of the rubber gasket when tightening the bolts and avoids disc jamming or water leakage.
• Ensure proper spacing between flanges—not too tight or too loose. Incorrect spacing may cause the internal gasket to be misaligned, resulting in poor sealing.
• Do not use additional gaskets or shims between the flange and the valve body, as the valve already has an integrated sealing ring.
• Flange size must match the valve size and comply with the connection standard (JIS, BS, ANSI, etc.) to ensure proper alignment and sealing.
• Do not weld the flanges while the valve is installed in the system, as heat can damage the gasket or deform the valve body.
• Installation orientation: The valve can be installed horizontally or vertically, depending on the pipe direction and actual operational requirements.
