- Buy 5 for $224.96 each and save 10%
The 247Garden 3-Inch Schedule-80 PVC True Union Ball Check Valve Socket-Type is built for high-capacity piping systems requiring reliable backflow prevention, chemical resistance, and extended service life. Designed for industrial water treatment systems, large-scale hydroponic setups, agricultural irrigation lines, and recirculation loops, this heavy-duty valve ensures unidirectional flow protection with minimal pressure loss and complete corrosion resistance.
With its true union configuration, this valve enables fast installation, effortless maintenance, and full disassembly without cutting into the pipeline. Ideal for demanding environments, the industrial-grade Schedule 80 PVC body and EPDM elastomers deliver superior strength, chemical compatibility, and sealing performance — making it a trusted component for residential, commercial, and industrial applications.
Product Specifications
-
Nominal Size: 3 inch
-
Connection Type: Socket/Slip (solvent-weld)
-
Material: Gray Schedule 80 PVC (UPVC-PW)
-
Seal Material: EPDM (ethylene propylene diene monomer) for broad chemical compatibility
-
Pressure Rating: Up to 235 PSI (non-shock at 73°F)
-
Temperature Range: 33°F to 140°F
-
Installation Orientation: Vertical preferred; horizontal acceptable with sufficient pressure and flow
9-Piece Assembly Breakdown
-
(2x) Schedule 80 PVC Socket End Connectors – solvent-weld ends for seamless pipe connection
-
(2x) Union Nuts – secure the valve body and allow full-service removal
-
(1x) PVC Valve Body – reinforced Schedule 80 housing for maximum pressure endurance and durability
-
(1x) Sealing Ball – precision-molded PVC ball lifts under forward flow and seals under reverse flow
-
(1x) Gland (Ball Retainer) – stabilizes the ball for smooth motion and precise seating
-
(1x) Stem O-Ring – seals the stem area to prevent internal leakage
-
(1x) Main O-Ring Seal (EPDM) – provides a tight barrier against backflow, UV wear, and mild chemical corrosion
How It Works
This valve uses a gravity-assisted, pressure-activated ball mechanism:
-
Forward Flow (Open): System pressure lifts the internal ball, allowing unrestricted flow.
-
Reverse Flow (Closed): When pressure drops or reverses, the ball returns to its EPDM seat, forming a reliable seal to stop backflow.
True Union Access: The union ends let you remove the valve body for cleaning, inspection, or seal replacement—without cutting pipe or using specialized tools.
Why Choose a True Union Ball Check Valve?
-
Full Serviceability: Easy removal and maintenance without system disruption.
-
No Metal Components: Corrosion-free construction for pure and long-lasting performance.
-
Quiet Operation: Soft-seating ball prevents water hammer and reduces flow noise.
-
Heavy-Duty Construction: Schedule 80 PVC body offers excellent strength and higher pressure capability compared to Schedule 40.
-
Chemical Resistance: EPDM seals handle fertilizers, chlorinated water, and mild acids with ease.
