Wespo butterfly valve seal is an important component for blocking all three potential leakage paths: the sealing of pipes, flanges and operating shafts, in shut-off valves, flap valves and disk valves. In their materials and design, they must be configured optimally for the respective application.
Wespo Sealing Technologies offer a precisely calibrated material quality and torque-reducing geometries. On one hand, they allow the flap to close with a low expenditure of force. On the other hand, they nonetheless feature a high pressing action for excellent sealing.
Butterfly valve seals are primarily used in the beverages ind , dairy Ind . and the pharma Ind . In the beverage industry, butterfly valve seals are mainly made of EPDM, which withstands aqueous media, CIP/SIP processes and acids. In addition to EPDM versions, dairy operations employ viton , silicone and Hnbr butterfly valve seals, since the high fat content of the process media must be taken into consideration. In pharmaceutical processing, depending on the medium, viton xp comes into use as another material option since it is resistant to the sector’s sometimes aggressive flavours .
Wespo have developed complete range of seatings/seals/seats for butterfly valves for Industrial and Food grade (FDA) application with all certificates.
Wespo butterfly valve seal also called rubber liner, sleeve or seals for butterfly type valves of various makes and models ranging from sizes 25 mm to 500 mm Dia in mm ,and are selling to many Indian companies as well as export
Wespo have capacity to Custom designs and sizes for specific requirements within a short time.
