DELCO DK66-4T Pneumatic 4-Way Ball Valve - Internal Thread, X-Port / L-Port Switching
The DELCO DK66-4T is a high-performance pneumatic 4-way ball valve designed for automated fluid switching and circulation control. Equipped with a rapid-response pneumatic actuator and threaded connections (NPT/BSP), it efficiently manages complex flow paths (X-port or L-port) in limited spaces, making it ideal for chemical, pharmaceutical, and water treatment automation.
Features
A compact pneumatic 4-way threaded ball valve offering automated X-port or L-port flow switching for efficient multi-pipeline control.
✅Automated Flow Switching: Integrated with a high-torque Rack & Pinion Pneumatic Actuator (Double Acting or Spring Return) for fast, remote-controlled operation and precise positioning.
✅Versatile 4-Way Configuration: Available in X-Port (Double L) for simultaneous reversing of two flow loops, or L-Port options, replacing multiple 2-way valves to simplify piping logic.
✅Secure Threaded Connections: Features standard Internal Threads (NPT / BSP / PT) for quick, leak-proof installation into existing industrial pipelines without welding.
✅ISO 5211 Direct Mounting: The valve body includes a standard ISO 5211 mounting pad, ensuring a rigid, zero-play connection between the valve and the actuator for consistent performance.
✅Durable Sealing System: Utilizes 4-sided PTFE/RPTFE seats to ensure a balanced, bubble-tight seal around the ball ports, preventing cross-port leakage even after frequent cycling.
