Product Introduction:
D81X grooved butterfly valve is a center-line soft-seal butterfly valve, employing a grooved (clamp) connection method and direct handle actuation.
Standard grooves are machined at both ends of the valve body, allowing for quick assembly with grooved pipelines via fire-fighting clamps.
The butterfly plate rotates from 0° to 90°, achieving both media cutoff and simple throttling, providing bidirectional sealing.
Its compact structure, lightweight design, and convenient installation make it a mainstream valve for fire sprinkler systems, HVAC, and water supply and drainage networks.
Features:
• Grooved clamp connection, fast installation & easy maintenance.
• Centerline structure, low operating torque, bidirectional bubble-tight sealing.
• Compact & lightweight, save installation space.
• Allow minor pipe displacement and thermal expansion.
• Ductile iron body with epoxy coating, anti-corrosion.
• Optional lockable lever or signal switch for fire service.
