This DIN cast iron butterfly valve features a wafer-style body that conforms to ISO 5752 S-20 (Series 50) face-to-face dimensions, ensuring direct interchangeability in existing pipelines. Designed specifically for marine and shipboard piping systems, it provides reliable flow control and tight shutoff for fresh water, seawater, oils, and non-corrosive gases. The valve's compact, lightweight construction minimizes space and weight requirements, ideal for engine rooms, cooling water circuits, ballast treatment, and general service lines.

Manufactured with a precision-machined cast iron body coated with a corrosion-resistant epoxy layer, the valve is paired with a stainless steel disc and stem for extended service life in demanding environments. The bubble-tight seal ensures zero leakage when closed, and the actuator mounting flange complies with ISO 5211, allowing easy installation of pneumatic, electric, or manual gearbox operators. Available in sizes DN50 through DN300, with pressure ratings PN10 and PN16, this valve meets the operational requirements of commercial, naval, and offshore applications.

As a listed IMPA 754401 item, this butterfly valve is a standard stock product for ship chandlers and carries the necessary approvals for use in Class societies. Its modular design simplifies maintenance, and replacement parts such as seals and seats are readily configurable to match specific media and temperature ranges.
