DESCRIPTION

Advanced Triple Offset Design

This valve features a three-dimensional eccentric design that eliminates friction between the disc and sealing surface during operation.

Unlike conventional butterfly valves, the disc moves away from the seat immediately after opening. This prevents unnecessary contact between sealing surfaces and significantly reduces wear.

The triple offset structure provides:

No friction during opening and closing
Extended valve service life
Lower operating torque
Improved sealing reliability
Reduced maintenance costs

Metal-to-Metal Sealing Performance

The valve adopts a durable metal-to-metal sealing system designed for high-temperature and corrosive environments.

The sealing surface uses a conical geometry that allows the disc and seat to separate quickly during operation. This prevents abrasion and reduces the possibility of material buildup on the sealing surface.

The metal sealing design provides:

Excellent leakage prevention
High temperature resistance
Corrosion resistance
Long-term sealing stability
Reliable performance in harsh conditions

The SS and flexible graphite sealing structure also supports fire-safe applications and high-temperature service requirements.

Key Benefits of Hastelloy Triple Offset Butterfly Valve

This valve offers outstanding advantages for industrial flow control and shut-off applications.

1. Excellent Flow Control Performance

The valve provides low flow resistance at full opening and accurate flow adjustment capability between approximately 15° and 70°.

It can be used as both a shut-off valve and a flow control valve, providing greater flexibility for industrial systems.

2. Suitable for Challenging Media

The wiping action of the disc movement helps prevent solids from accumulating on the sealing surface.

This design makes the valve suitable for applications involving:

Suspended particles
Powder materials
Granular media
Corrosive process fluids

3. Reliable Zero Leakage Performance

The optimized sealing structure ensures tight shut-off performance and helps achieve zero leakage under proper operating conditions.

4. Reduced Maintenance Requirements

The friction-free operation and durable sealing materials reduce wear, extend service intervals, and lower lifecycle costs.
