Technical Information

This 3″ Schedule 40 PVC Ball Valve features a full-port design that provides unrestricted flow when fully open. The true union design allows for easy removal for maintenance without disturbing the connected piping. The pressure rating decreases as temperature increases:

150 PSI @ 73°F
135 PSI @ 90°F
105 PSI @ 110°F
70 PSI @ 140°F

Key features include:

Positive stop handle with ergonomic grip
Blowout-proof stem design for safety
Double O-ring stem seals for leak prevention
PTFE seats for smooth operation and extended cycle life
Full-port design reduces pressure drop across the valve

Applications

Water treatment systems
Chemical processing
Swimming pool and spa systems
Irrigation systems
Industrial fluid handling
Water distribution
Process control
Wastewater treatment

Installation Guidelines

For socket connections, use appropriate PVC primer and cement
Allow proper curing time according to cement manufacturer instructions
Install with flow direction matching directional arrow (if present)
Provide adequate support on both sides of the valve
Do not use as a throttling valve – recommended for fully open or fully closed positions only
Leave clearance for handle operation
Operate periodically to prevent seizing
Allow 24 hours curing time before pressure testing
Hand-tighten union nuts only – do not use metal tools that may damage threads
