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
A rising stem design allows the stem position to indicate valve opening and closing, while a non-rising stem design keeps the stem within the valve body. The choice depends on available installation space, operating requirements and project specifications.
RKSfluid Resilient Seated Gate Valves are available from DN40 to DN1000 for non-rising stem designs and DN40 to DN600 for rising stem designs. Pressure ratings include PN10 and PN16, with additional PN25 options depending on size and configuration.
These valves are designed for raw water, drinking water and sewage applications. The resilient seat provides reliable sealing for water pipeline systems when the valve is selected according to the required pressure, temperature and medium.
Depending on the configuration, the valve can be designed according to BS 5163, DIN 3352 or AWWA C515. Face-to-face dimensions may follow BS 5163, DIN 3202 F4/F5 or AWWA C515.
RKSfluid Resilient Seated Gate Valves can be configured according to project requirements, including EN 1092-2, ASME B16.10 and AS 4087 flange requirements. The flange standard should be confirmed before ordering.
The valve body is made of ductile iron, while the disc uses ductile iron with NBR or EPDM sealing. The appropriate sealing material should be selected according to the medium and operating conditions.
Yes. They are widely used in water supply and water treatment systems, particularly where reliable shut-off and low-maintenance operation are required. They are suitable for raw water, potable water and sewage applications.
Selection should consider DN size, pressure rating, stem type, flange standard, medium, temperature and installation space. For EPC projects, the applicable design standard and pipeline specifications should also be confirmed.
