Features

• Triple offset (triple eccentric) disc geometry
• Metal-to-metal sealing for zero-leakage shut-off
• Reduced friction between disc and seat during operation
• Suitable for both throttling and isolation duty
• Flanged end connection for stable installation in large pipeline systems
• Compatible with manual, pneumatic, or electric actuators
• Triple-offset (triple-eccentric) disc geometry visible on multiple units
• Flanged end connections (double-flanged body)
• Worm gear actuator fitted as standard on multiple variants
• Gear operator with handwheel operation
• Extended stem/bonnet arrangement visible on one variant (image 2)
• Metal seat sealing visible on disc face
• Available in stainless steel body/disc construction (images 0, 4)
• Available in carbon steel / ductile iron body with stainless disc (images 2, 5)
• Red-painted body variant with stainless disc (image 3) — indicative of fire-safe or high-pressure service
• Blue-painted cast iron/ductile iron body variant (images 2, 5)
• Multiple units shown ganged together indicating batch/manifold configurations

Notes

• Optional actuators—manual, pneumatic, or electric—can be added to suit automation requirements.

Description

A triple eccentric (triple offset) flanged butterfly valve utilising metal-to-metal sealing for tight shut-off in high-pressure and high-temperature service. The disc and seat geometry reduces friction during operation. Available with manual, pneumatic, or electric actuation to suit isolation or throttling duties.
