The Difference Between A Lug and Wafer Butterfly Valve
2019-02-12 16:59:28
Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.
Wafer type butterfly valve installation instructions and steps
2019-01-03 16:27:13
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.

MINOTAUR series replaceable seat high performance butterfly valve
Tilting Check Valve
- Size: DN100 - DN2000
- Pressure Ratings: PN10, PN16, PN25
- Temperature Range: -20°C ~ +80°C
- Body Material: Ductile iron, Cast iron, Stainless steel, WCB
- Medium: EPDM, Stainless steel
- Connection: SS420, SS431
- Face to Face: Hydraulic, Manual
- Product Details
The series tilting type check valve is designed to prevent reverse flow in pipelines while ensuring smooth and reliable operation in large diameter systems.
Compared with conventional swing check valves, the tilting disc structure provides faster closing response and reduces the risk of water hammer. The valve uses a heavy hammer assisted closing mechanism that ensures stable shut-off, making it suitable for municipal water supply, pumping stations, and industrial pipelines.
This type of check valve is widely used in water treatment plants, pumping stations, power plants, and long-distance pipeline systems where flow reliability and equipment protection are critical.
Key Features
- Fast Closing to Reduce Water Hammer: The tilting disc design allows quick closure when flow stops.
- Reliable Backflow Prevention: Prevents reverse flow and protects pipeline equipment.
- Durable Materials: Body available in ductile iron, cast iron, WCB, or stainless steel.
- Low Pressure Loss: Streamlined disc minimizes flow resistance.
- Flexible Operation: Hydraulic or manual options available.

Working Principle
The valve operates using a disc that tilts open with forward flow. When the flow decreases or stops, the disc returns to the closed position assisted by the heavy hammer.
This controlled closing action prevents reverse flow and minimizes pressure shock.
FAQs
A tilting butterfly check valve prevents reverse flow in water pipeline systems. Its disc design allows controlled opening and closing and is suitable for large-diameter applications such as water supply, irrigation and industrial water systems.
RKSfluid Tilting Butterfly Check Valves are available from DN100 to DN2000 in PN10, PN16 and PN25 pressure ratings. The correct size and pressure class should be selected according to the pipeline design and operating conditions.
The tilting disc design can provide smooth opening and closing characteristics while helping reduce flow resistance and closing impact. This makes it suitable for large-diameter water pipelines and pumping applications.
The standard configuration is designed for water service. Typical applications include water distribution and treatment, irrigation and heating systems. Special media should be reviewed separately based on operating conditions and material requirements.
The valve uses EN 558-1 Series 13/14 face-to-face dimensions. Flange configurations can be provided according to EN 1092-2 or ASME B16.5 requirements.
The standard operating temperature range is -20°C to +80°C. The actual temperature and pressure conditions should be confirmed when selecting the valve for a specific project.
Yes. With sizes up to DN2000, the valve is suitable for large-diameter water supply, distribution, treatment and irrigation systems. It can also be considered for heating, shipbuilding and industrial process applications.
Important factors include DN size, pressure rating, flow direction, medium, temperature, flange standard and installation conditions. For pump and large pipeline projects, hydraulic conditions should also be considered.
