Discription
Product Overview
The Electric Fully Welded Ball Valve is a high-performance solution specifically designed for the control of main pipelines in the petroleum, chemical, and natural gas industries. Featuring a fully welded body that eliminates potential external leakage paths, it is ideal for buried (underground) installations and insulated piping networks. This valve is compatible with various media, including water, oil, gas, brine, and chemicals, operating reliably within a temperature range of -29°C to +200°C and pressure ratings up to 2500LB (PN42 MPa).
Product Features
-
Maintenance-Free Welded Design: The integrated fully welded body eliminates joint leakage risks and requires no lubrication or regular maintenance, ensuring a long service life in underground or inaccessible locations.
-
Advanced Material & Sealing: Constructed with high-grade materials (e.g., 20#, A105) and featuring PPL or Metal-to-Metal hard sealing, providing zero-leakage performance under extreme pressure conditions.
-
Certified Safety Standards: Engineered to meet API 6D and ASME B16.34 standards, with fire-safe performance certified to API 6FA and API 607, ensuring operational safety in hazardous environments.
-
Optimized Flow & Operation: The Full Bore design ensures minimal pressure drop and allows for smooth pipeline pigging. It is equipped with a high-precision electric actuator for rapid response and precise control.
-
Robust Protection: Treated with high-performance anti-corrosion coatings and equipped with anti-static devices, the valve is built for all-weather durability and safety against static discharge.
-
Automatic Pressure Relief & Safety: The floating seat design compensates for internal pressure changes, ensuring the valve remains safe and easy to operate even under high-load conditions.
