DELCO DK67-DC Pneumatic Cast Iron Butterfly Valve - PTFE Lined / Rubber Seat, Wafer Type
The DELCO DK67-DC is a versatile pneumatic wafer butterfly valve featuring a cost-effective Ductile Iron (GGG50) body. Available with either a corrosion-resistant PTFE/FEP lining for chemical applications or an economical NBR/EPDM seat for general water systems. Driven by a high-torque AT Series Pneumatic Actuator, it ensures reliable automation for diverse industrial pipelines.
Features
A versatile pneumatic wafer butterfly valve with a ductile iron body and PTFE lining or rubber seat options, offering cost-effective automation for chemicals and water.
✅Corrosion-Resistant Lining: The fully lined PTFE or FEP seat option isolates the cast iron body from the medium, providing exceptional chemical resistance similar to Stainless Steel Lined Valves, but at a fraction of the cost.
✅Economical Rubber Option: Also available with a replaceable NBR or EPDM seat for non-corrosive media like municipal water and compressed air, offering a budget-friendly solution for general utility lines.
✅Reliable Pneumatic Automation: Powered by a Rack & Pinion AT Pneumatic Actuator (Double Acting or Spring Return), delivering high output torque and fast response times for precise process control.
✅Robust Ductile Iron Body: Constructed from high-strength Ductile Iron (GGG50) coated with epoxy resin for rust prevention, ensuring durability in harsh industrial environments.
✅Zero-Leakage Sealing: The precision-machined disc and resilient seat design guarantee a bubble-tight shutoff, preventing leakage even in low-pressure systems.
