Features PVC-U ball valves - Standard Series

• Antiblock" system that avoids the ball blocking.
• 100% factory tested
• Minimal pressure drop
• Low opening and closing torque
• Resistance to multiple inorganic chemicals
• Excellent handling characteristics 

Specifications standard threaded ball valve

• PVC-U body
• Female thread
• Metric series
• HDPE ball seat seals
• O-rings in EPDM
• Blue marking: EPDM seals, to be chosen according to the fluid.
