DK66-3PS-HG Pneumatic 3-Piece High-Pressure Ball Valve - Fast Isolation & High WOG Service
The DK66-3PS-HG Pneumatic High-Pressure Ball Valve is engineered for demanding severe-service applications requiring both extreme pressure containment and rapid automated control. Built with a heavy-duty body capable of handling significantly high working pressures (e.g., 3000 PSI, 6000 PSI, or higher), this valve utilizes the signature 3-Piece design for quick inline maintenance of seats and seals without major pipeline disruption. Coupled with the pneumatic actuator, it delivers rapid, reliable quarter-turn isolation, making it essential for hydraulic systems, high-pressure injection lines, and industrial test equipment.
Size Range: DN06-DN100
Material: WCB, Stainless Steel etc.
Connection Standard: G / BSPT / NPT
Features
A robust pneumatic 3-piece ball valve designed for fast, automated on/off control and superior maintainability in extremely high-pressure environments.
✅Extreme High-Pressure Rating: Specifically built to handle high working pressures (HG - High Grade/High Pressure), providing safety and integrity in critical hydraulic power and fluid injection applications.
✅Rapid Pneumatic Control: The actuator ensures immediate, quarter-turn operation, crucial for quickly achieving process isolation or emergency shutoff in high-pressure lines.
✅3-Piece Swing-Out Maintenance Design: The structure allows the valve's central body to be easily removed for servicing (seals, seats) while the end connections (typically threaded or socket weld) remain in the pipeline, minimizing downtime.
✅Heavy-Duty Construction: Constructed from high-strength materials (Stainless or Carbon Steel) with reinforced components to safely and reliably withstand the high mechanical stresses associated with high-pressure fluid transfer.
✅Reinforced Tight Shutoff: Features specialized seating materials (such as PEEK or reinforced PTFE) and construction engineered to maintain positive, bubble-tight isolation even under maximum rated pressures.
