What does "bi-directional zero leakage" mean?

It means the valve provides bubble-tight shut-off in both flow directions. Each valve is 100 percent tested per API 598 to verify zero leakage performance.

Do you provide OEM and ODM services?

Yes, both OEM and ODM services are available.

Key features

All wetted parts made of Hastelloy C276 (Nickel Chromium-Molybdenum alloy) for superior corrosion resistance in aggressive chemical environments.

Advanced double eccentric (double offset) design minimizes seat wear, reduces operating torque, and significantly extends valve service life

Unique seat design enables bubble-tight shut-off in both flow directions, meeting API 598 zero leakage requirements.

Engineered with field-replaceable seat for easy maintenance and reduced downtime, extending overall valve lifecycle.

Precision machined flange faces with 125-500 microinch roughness for reliable sealing with standard gaskets.

Standardized ISO 5211 mounting flange allows direct assembly with worm gear, electric, pneumatic, and hydraulic actuators.

Reliable performance from cryogenic to high temperature applications without compromising sealing integrity.

Excellent resistance to wet chlorine, chlorides, sulfuric acid, oxidizing salts, and aggressive chemicals.

Each valve tested per API 598 for shell strength and seat leakage to ensure reliable performance

Manufactured under API 609 standard, the dedicated specification for butterfly valves ensuring quality compliance.
