Overview

The DSBC-63-250-PPVA-N3 is a pneumatic ball valve engineered for precise fluid control in demanding industrial environments. Its polypropylene (PP) body ensures corrosion resistance, while the stainless steel ball provides durability against abrasive media. The valve's 63mm nominal diameter and 250mm stroke make it suitable for mid-sized pipelines requiring fast actuation. Designed for automation, it integrates seamlessly with pneumatic systems, offering rapid response times and reliable shut-off. Common certifications include ISO 5211 for mounting standards and ATEX for explosive environments (if applicable). Its modular design allows easy retrofitting into existing systems.

Structure and Working Principle

The valve comprises a PP body, a rotating stainless steel ball with a bore, and a pneumatic actuator. When compressed air is supplied, the actuator rotates the ball 90 degrees, aligning the bore with the pipeline (open) or perpendicular to it (closed). The PTFE seats ensure leak-proof performance. The double-acting or spring-return actuator variants cater to different fail-safe requirements. Position indicators (mechanical/electrical) are often optional for automation feedback. The 250mm stroke length optimizes torque output for smooth operation under typical line pressures.

Key Features

1. **Corrosion Resistance**: PP body resists chemicals, acids, and alkalis, ideal for water treatment and chemical industries. 2. **Pneumatic Efficiency**: Actuator response time under 1 second reduces process downtime. Optional solenoid valves enable remote control. 3. **High Sealing Performance**: PTFE seats and stem seals achieve bubble-tight shut-off (ANSI Class VI), minimizing leakage risks.

Application Areas

1. **Water Treatment**: Controls flow in filtration, dosing, and disinfection systems. PP material withstands chlorine and ozone. 2. **Chemical Processing**: Compatible with mild acids, alkalis, and solvents; avoids metallic contamination. 3. **Manufacturing**: Used in automated production lines for cooling water, compressed air, or inert gases.

Maintenance and Precautions

Regularly inspect seals and actuator for wear; replace PTFE seats every 50,000 cycles under abrasive conditions. Lubricate the stem annually with compatible grease. Avoid exceeding the rated pressure (typically 10-16 bar) or temperature range (-10°C to 120°C for PP). Ensure air supply is filtered and dry to prevent actuator damage. Isolate the valve during system cleaning to avoid chemical exposure to seals.

B2B Procurement Guide

When sourcing the DSBC-63-250-PPVA-N3, confirm technical specs: pressure rating (PN10/PN16), actuation type (double-acting for 100% duty cycle, spring-return for fail-safe), and connection standard (e.g., DIN flange). Bulk orders (50+ units) may attract 10-20% discounts. Lead times vary from 2-6 weeks; prioritize suppliers with ISO 9001 certification. For custom needs (e.g., NAMUR actuator mounting), provide CAD drawings early. Compare after-sales support, including warranty (typically 1-2 years) and spare parts availability.
