When selecting materials for wafer butterfly valves, a comprehensive combination of materials should be made based on the media type, temperature and pressure rating, and cost budget.

For example,

*In conventional water treatment or HVAC systems, a ductile iron/WCB wafer butterfly valve body + EPDM seat + ductile iron disc can be used. This combination is suitable for general industrial pipelines without corrosive media.

* If the media is corrosive, a stainless steel wafer butterfly valve body + PTFE seat + stainless steel disc (or PTFE lined disc) is recommended. This combination is suitable for pipelines with media temperatures not exceeding 180 degrees Celsius.

* For automated control systems, electric wafer butterfly valves or pneumatic wafer butterfly valves can be configured.

* For precise regulation, a high-performance wafer butterfly valve can be considered to meet the application requirements of flow control wafer valves. Wafer HP butterfly valves typically consist of a WCB/stainless steel butterfly valve body and disc, + an RPTFE seat.

* For high-temperature and high-pressure applications, a wafer-type eccentric butterfly valve can be selected, as only metal seats can meet this requirement.

* The food and chemical industries, however, prioritize the cleanliness and sealing performance of the wafer-type butterfly valve body, seat, and disc materials.

As a professional wafer butterfly valve manufacturer and supplier, ZFA has been providing OEM customization services for wafer butterfly valves since 2006. Therefore, we can tailor a solution to your specific needs; please feel free to contact us.

Wafer Butterfly Valve Types

1. Connect

DN≤600, wafer type. It has no/two/four/eight ears on the upper and lower body.
600≤DN≤1200, single flange type. It has one flange in the middle of body.

The single flange butterfly valve has the same Structure length (FTF) with wafer type, and the same stability with double flanged butterfly valve.

2. Valve seat

--Soft Seal--

Hard-Back Seat:

The material is composed of a hard back wrapped with rubber on the outside. The installation method is to use a professional valve assembly platform to press the valve seat into the valve body through a machine. At the same time, the The valve seat is also classified into ordinary type and waterline type.

Soft-Back Seat:

The entire material is composed only of rubber, so it is highly elastic and is also called a backless valve seat. Its installation method is more convenient for workers to repair, replace and disassemble later.

Vulcanization:

The rubber lining in the rubber-lined butterfly valve uses high temperature to vulcanize the rubber and the valve body into one body. This valve seat has very high anti-corrosion properties and is generally used to control some corrosive fluids with strong acid and alkali. The disadvantage is that the valve is disposable and if the vulcanized valve seat is damaged, the entire butterfly valve needs to be replaced.

--Hard Seal--

Eccentric type, use body seal or other metal materials such as stainless steel, bronze, graphite etc. Contact Us!
