Resilient Seated Butterfly Valve – Series 36H, High-Performance Double Flanged, ISO 5211 Mount

The Resilient Seated Butterfly Valve Series 36H is engineered for robust industrial applications requiring precise flow control and bi-directional sealing. With a heavy-duty, long-pattern double flanged body, the 36H offers superior strength and stability in water, wastewater, power, and industrial process pipelines.

Its fully encapsulated resilient liner ensures bubble-tight shutoff and reduces wear caused by cyclic operation. The valve body is manufactured from ductile iron and features ISO 5211 mounting capabilities for direct connection to actuators, reducing installation complexity. The concentric disc design and full-bore configuration minimize pressure drop and improve flow efficiency.

The 36H Series is compliant with international flange, testing, and mounting standards, making it a reliable and cost-effective solution for high-cycle, corrosive, or abrasive service conditions.
