Overview
A Slab Gate Valve is a linear motion isolation device featuring a flat, solid wedge or slab as the closing element. It utilizes precision-machined metal-to-metal sealing surfaces to ensure tight shut-off under high pressure and abrasive conditions.
Application
- Petrochemical Refineries: Crude oil pipelines and fractionation towers.
- Oil & Gas Drilling: Blowout preventers (BOP) and wellhead assemblies.
- Power Generation: Coal pulverizing systems and ash handling lines.
- Chemical Processing: Slurry transport and corrosive fluid isolation.
Precautions
- Temperature: Operate strictly within -29°C to 450°C depending on material grade.
- Pressure: Adhere to ANSI Class ratings; avoid rapid cycling to prevent seat damage.
- Maintenance: Regularly lubricate stem threads and inspect packing for leakage.
