DK67-FB Pneumatic Cast Iron Wafer Butterfly Valve - EPDM Sealed for Fast Utility Control
The DK67-FB Pneumatic Wafer Butterfly Valve is a reliable and cost-effective solution for automated flow isolation in large-volume utility lines, including water, air, and HVAC systems. It features a durable Cast Iron body and a resilient EPDM liner/seal, providing excellent elasticity and resistance to mild chemicals and hot water. The wafer design is compact and lightweight, minimizing installation space. Coupled with a pneumatic actuator, the valve ensures rapid, quarter-turn on/off control for quick process cycling and efficient flow management.
Features
A cost-effective pneumatic cast iron wafer butterfly valve with EPDM sealing, designed for fast, automated on/off control and reliable isolation in general utility and bulk fluid transfer applications.
✅Rapid Pneumatic Automation: The pneumatic actuator provides immediate, high-speed, quarter-turn operation, ideal for quick system isolation and efficient process cycling in high-volume pipelines.
✅Durable EPDM Sealing: Equipped with an EPDM (Ethylene Propylene Diene Monomer) liner and seal, offering excellent resistance to water, steam, non-petroleum based fluids, and many polar chemicals.
✅Cost-Effective Cast Iron Wafer Body: The Cast Iron construction provides high mechanical strength at an economical price point, while the wafer (lugless) body design minimizes face-to-face dimensions and weight.
✅High Flow Efficiency: The inherent butterfly valve structure provides maximum flow capacity and minimal pressure drop, contributing to optimized energy usage in large-scale fluid transfer systems.
✅Secure Wafer Installation: The wafer-style body fits securely and centered between pipeline flanges, ensuring proper alignment and tight sealing during installation.
