Wafer Butterfly Valve
Our Cast Iron Wafer Butterfly Valve with Pneumatic Actuator offers a compact, efficient, and cost-effective solution for automated flow control in a wide range of industrial pipelines. Designed with a high-tensile cast iron body (EN-GJL-250) and a wafer-type connection, this butterfly valve ensures excellent durability and space-saving installation between flanges (ANSI 150, PN10/16).
Equipped with a double-acting or single-acting pneumatic actuator, our valve allows for fast, accurate, and remote operation, with torque output ranging from 50 Nm to 2,000 Nm. The actuator is ISO 5211 compatible, supporting easy mounting and replacement.
Product Description
