Butterfly Valves

Butterfly valves are a great choice for applications where standardized shut-off is required. They provide a low-torque rotation of 90 degrees and tend to be less expensive and lighter in weight, making them popular with operators. Butterfly valves are often distinguished by their three main types: Zero Offset or Centric Type, Double Eccentric or Double Offset Type & Triple Eccentric or Triple Offset.

JossMin’s offers Centric and Double Eccentric Butterfly Valves designed to meet the ASME Standards. The designs provide for easy actuation at all actuator torques, as well as a superior seal in the closed position. Available in a wide range of materials to suit varied industrial needs in the Universal Wafer Design and in a variety of end connections

For applications involving corrosive mediums, PFA / FEP Lined are available. Metal Seated Butterfly Valves are also available with electro-pneumatic automations for high temperature or operations involving slurry media.

Double Eccentric Butterfly Valves with Automations

With the double-offset structure, the Valve disc can leave the Valve seat quickly, greatly reducing unnecessary over-compression and scraping between them. This structure also helps decrease the wearing process and prolongs the operational life of the Valve. The Valves may be used in vacuum and with non-corrosive materials in Pharma, Food, and Beverage industries.

All Valves come with an antistatic stem design and offer bidirectional flow. The Butterfly Valve can be used for On-off, Modulating as well as Batching applications

All Valves are manufactured, assembled and tested in house to ascertain only the best in quality.
