Butterfly Valves

Industrial Butterfly Valves

Reliable Flow Control Solutions for Bulk Material Handling Systems

Product Description

Butterfly valves are designed to regulate the flow of free-flowing bulk materials such as powders, granules, pellets, and particulate products—especially in gravity-discharge applications.
The internal disc rotates around its axis through a pneumatic or electric actuator, or a manual operating lever, enabling precise shut-off, opening, flow regulation, weighing, and dosing operations.

SYORITEC butterfly valves are engineered to meet the requirements of various industrial environments and material characteristics. Available in several body and disc materials:

Valve Body Materials

• Cast iron

• Aluminum die-cast

• Carbon steel

• Stainless steel AISI 304 / AISI 316

• Wear-resistant Hardox steel

Disc (Blade) Materials

• Carbon steel

• Hardox

• Stainless steel AISI 304 / AISI 316

Seals (Gaskets)
