Offering a wide range of bi-directional triple eccentric butterfly valves with zero leakage. Low torque ensures easy operation, and the metal seat design allows for use in harsh environments.
Seats and seals are replaceable and can be maintained online. Triple offset butterfly valve complies with API609 standard.
Size: 2″~120″ (DN50~DN3000)
Pressure level: ASME CLASS 150~2500
Main material: carbon steel, stainless steel, alloy steel, duplex stainless steel
Terminal connection: LUG
Operation mode: gear, pneumatic, electric, hydraulic
Class 150 to Class 2500 rated valves
Advantage:
metal base
Closed in both directions
Zero leakage
Replaceable disc seal
Save costs through smart design
Metal base:
Metal-to-metal seal ensures zero leakage
The valve does not require a plug in the closed position, the valve body is a natural plug for the sealing ring
Inherently fire resistant by design
Disc cannot pass through seat in overtravel position
Applying higher torque results in greater sealing ability
Less maintenance required and lifetime cost savings
Better operability
longer life
Operation speed
Requires lower torque than other valve designs, especially ball valves
Suitable for modulation applications
safety:
Fire safety is ensured through design:
No soft parts will burn in a fire
No change in valve performance before, during and after fire
Meaning zero leakage performance is ensured before, during and after a fire
Successfully passed the fire safety test and met the following requirements:
– API 607 (7th edition)
– BS EN12266-1:2003
– ISO 10497 – 2010
Zero leakage:
Successfully passed zero leakage test.
NOTE: Bubble seal is the most commonly misused term in the valve industry!
Air tightness per ANSI B16.104 cl.VI/API 598/MSS SP61 means leakage is allowed.
For example, for an 8-inch valve, 45 bubbles per minute are allowed; for a 24-inch valve, 400 bubbles per minute are allowed.
Intelligent design saves costs
Requires less maintenance, resulting in cost savings over its lifetime
longer life
Requiring up to 80% less material compared to ball valves, the potential for cost savings is huge for new and replacement projects
