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.

FAQs
Metal-seated gate valves use metallic seating surfaces, such as brass or bronze, while resilient-seated designs use an elastomer-covered wedge. This difference affects the sealing interface and should be considered when selecting a valve for a specific water service.
Check the nominal size, pressure rating, face-to-face length, flange drilling and operating conditions. Matching the connection dimensions is essential when replacing a valve without modifying the pipeline.
F4 and F5 define different face-to-face dimensional series. The required series must match the pipeline layout or specified valve dimensions; they should not be treated as interchangeable.
The nominal pressure rating should be selected against the pipeline design pressure and applicable engineering standard. RKSfluid's listed ratings are PN10, PN16, PN25 and PN40.
The main considerations are water chemistry, corrosion resistance, material compatibility and project specifications. Brass and bronze are available seating-material options for this product range.
Face-to-face dimensions and flange drilling must both match the pipeline specification. Relevant references include BS 5163 or DIN 3202 F4/F5 for dimensional requirements, and EN 1092-2 or AS 4087 for flange requirements, as applicable.
Include size, pressure rating, quantity, design standard, face-to-face dimension, flange drilling, water-service conditions and required material documentation. This helps reduce clarification rounds during technical review.
The listed maximum operating temperature is 80°C. Selection should also account for the specified pressure rating, water conditions and installation requirements.
