Product Overview
API 600 High-Pressure Self-Sealing Gate Valve: NEWWAY Cast Steel and Alloy Steel Power Station Flange Gate Valve Professional Analysis
I、Product Overview: Sealing Solutions for High-Pressure Applications
NEWWAY API 600 high-pressure self-sealing gate valves are industrial valves designed to API 600 standards, suitable for harsh conditions involving high pressure, high temperature, and corrosive media. Manufactured from cast steel (A216 WCB) and alloy steel (A217 WC6, WC9, etc.), these valves feature a self-sealing structure, ensuring reliable fluid control in industries such as power stations, petrochemicals, and metallurgy. The core function lies in the precise fit between the gate and seat to intercept or circulate media, while using medium pressure to enhance sealing performance and eliminate leakage risks from traditional flange seals.
II、Core Features: Self-Sealing Design and Operational Adaptability
Advantages of Self-Sealing Structure
The self-sealing design ensures that the seal between the bonnet and body relies on the medium’s own pressure—the higher the pressure, the more reliable the seal. This design reduces bolt quantity and pre-tightening force requirements, simplifying installation and maintenance, especially for high-pressure systems ranging from Class 150 to Class 2500 (PN16 to PN420).
Wide-Range Operational Adaptability
Size Coverage: Port sizes from NPS1/2″ (DN15) to NPS72″ (DN1800) meet integration needs for different pipe diameters.
Temperature Resistance: Suitable for high, medium, and low-temperature media, with materials including WCB, WC6, WC9, CF8M, etc., adapting to -29℃ to 540℃.
Medium Compatibility: Supports various media such as water, oil, acids, and gases, widely used in corrosive or flammable environments.
Multi-Mode Operation and Connections
Operations include manual, electric, pneumatic, and gear-driven types to suit different automation needs. Connection types cover flanged, welded, threaded, BW (butt weld), SW (socket weld), etc., ensuring on-site installation flexibility.
