Tripple Eccentric Butterfly Valve

NSV Tripple Eccentric Butterfly Valve

This Manual Operated Tripple Eccentric Butterfly Valve is designed for low-temperature and high-pressure services requiring reliable shut-off. It incorporates a tripple eccentric high-performance sealing design and a Low-Temperature Carbon Steel body, ensuring exceptional sealing integrity and structural strength in demanding cryogenic and high-pressure environments. It is an ideal solution for LNG, cryogenic chemical, and other critical low-temperature applications.

Key Features

Body Material Optional LCB or LCC low-temperature carbon steel, suitable for temperatures down to -46°C

Operation Manual handwheel, designed for high-torque output and secure positioning

Pressure Maximum rating up to 2500LB

Size Range Nominal diameters from DN200 to DN1000 (40”)

Sealing Tripple eccentric metal seat, bidirectional bubble-tight shut-off

Standards Compliant with API 609 and ISO 10631

Operation & Advantages

Rotating the handwheel operates the valve stem to smoothly control the large disc.

The tripple eccentric design ensures the disc completely disengages from the seat upon opening, achieving zero-wear operation. Combined with spring-loaded sealing technology, it guarantees tight sealing under both high pressure (2500LB) and cryogenic conditions.

Specially treated low-temperature carbon steel ensures the valve body maintains superior impact resistance at -46°C, eliminating any risk of brittle fracture.

Typical Applications

Suitable for high-pressure LNG transfer pipelines, cryogenic chemical processing units, high-pressure liquid nitrogen/oxygen storage and transfer systems, and large-bore high-pressure low-temperature pipelines requiring reliable manual control.

Quality Control & Service

Body castings strictly conform to ASTM A352 LCB/LCC and related standards for low-temperature carbon steels, with low-temperature impact test reports provided.

Each valve undergoes rigorous shell strength tests and high-pressure seat leakage tests that far exceed working pressures.

Professional technical support from selection to installation, along with comprehensive after-sales service, is provided.
