Description

The BUTTERFLY VALVE STEEL WAFER TYPE DIN PN 16 is a high-performance industrial valve designed for reliable flow control in demanding applications. Constructed from durable steel, this valve ensures excellent resistance to pressure, corrosion, and wear, making it ideal for use in water treatment, chemical processing, oil and gas, and HVAC systems. Its wafer-type design allows for easy installation between flanges, reducing space requirements and overall weight without compromising on strength or functionality.This valve complies with DIN standards and is rated for PN 16 pressure, guaranteeing safe operation under high-pressure conditions up to 16 bar. Key features include a compact and lightweight body, a bubble-tight seal for zero leakage, and a smooth operation mechanism that minimizes torque requirements. The disc is precision-engineered to provide efficient flow regulation with minimal pressure drop, enhancing system efficiency and reducing energy costs.Applications and benefits of this butterfly valve include:Suitable for on/off and throttling services in various industrial sectorsRobust steel construction ensures long service life and reduced maintenanceWafer design simplifies installation and lowers total cost of ownershipCompatible with a wide range of fluids, including water, air, gases, and mild chemicalsMeets international standards for quality and safety, providing peace of mind in critical operations
