Refrigeration Parts Shut off Valve BV-28 Ball Valve with Access Port

Product Description

Product Description

Product Description:

This cam-action ball valve (also known as orbit ball valve) is designed for zero-friction opening and tight shut-off in high-pressure, high-temperature, or hazardous fluid services such as hydrogenation units, oxygen pipelines, toxic gas isolation, and emergency shutdown systems in refineries, chemical plants, and power stations. It features a unique operating principle: the ball first lifts off the seat vertically during the initial turn of the stem, then rotates 90 degrees without contacting the seat, eliminating sliding wear and seat abrasion. The valve body is forged from alloy steel or stainless steel with a corrosion-resistant coating. The ball is hard-faced with a wear-resistant alloy, and the seat is made of hardened stainless steel with a Stellite overlay, providing metal-to-metal sealing. A blow-out-proof stem with live-loaded graphite packing ensures zero fugitive emissions. The valve is equipped with a gearbox actuator and a position indicator. Flanged connections per DIN or ASME B16.5. Pressure rating: up to 25 MPa (Class 1500), temperature range: -40°C to 500°C, sizes: DN15 to DN400. Designed for bidirectional bubble-tight shut-off and emergency shutdown (ESD) applications requiring reliable performance after long periods of inactivity.

Key Features & Selling Points:

(1) Cam-action lifting mechanism separates ball from seat before rotation, eliminating friction wear during opening and closing, achieving 1 million cycles without seat replacement.

(2) Metal-to-metal sealing with hardened Stellite seat provides bubble-tight shut-off at pressures up to 25 MPa and temperatures up to 500°C, suitable for severe service.

(3) Zero-friction design prevents galling and seat damage in contaminated or abrasive media, maintaining seal integrity after prolonged inactivity.

(4) Bi-directional sealing capability with rated differential pressure from either direction, ideal for double block applications.

(5) Live-loaded graphite stem packing and blow-out-proof stem ensure zero leakage to atmosphere, meeting stringent fugitive emission standards for toxic gas service.
