APV Big-Bore™ Straight-Down Metering Valve – Tungsten Carbide Sleeve

Model: 888-2151-200PB
Category: Surface Preparation → Sandblasting Equipment → Abrasive Metering Valves
Type: Big-Bore™ Abrasive Metering Valve (Straight-Down, Tungsten Carbide Sleeve)

The APV Big-Bore™ Straight-Down Metering Valve – Tungsten Carbide Sleeve is a high-capacity, heavy-duty valve engineered for maximum abrasive flow in large-nozzle blasting applications. Designed for demanding industrial environments, this valve is ideal for use with #8, #10, and #12 nozzles, as well as spin blasters with 5/16" and larger nozzles, where standard valves may restrict performance.

Key Features & Benefits

• Designed for high-flow Big-Bore™ blasting applications
• Ideal for #8, #10, #12 nozzles and 5/16"+ spin blasters
