- Buy 12 for $80.96 each and save 10%
The 247Garden 2-Inch Schedule-80 PVC True Union Ball Check Valve Socket-Type is designed for large-diameter piping systems that demand reliable backflow prevention, superior chemical resistance, and long-term durability. Built to perform in high-flow hydroponic mainlines, irrigation control networks, water treatment systems, and industrial recirculation loops, this heavy-duty valve ensures one-way flow protection with minimal pressure loss and zero risk of corrosion.
With its true union design, this valve enables quick installation, easy maintenance, and full disassembly without cutting into the pipeline—allowing for effortless inspection, cleaning, or seal replacement. Crafted from industrial-grade Schedule 80 PVC and EPDM elastomers, the 2-inch ball check valve delivers exceptional pressure performance and chemical stability, making it a reliable choice for residential, commercial, and light industrial applications.
Product Specifications
-
Nominal Size: 2 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
-

9-Piece Assembly Breakdown
-
(2x) Schedule 80 PVC Socket End Connectors – solvent-weld ends for seamless pipe integration
-
(2x) Union Nuts – secure the valve body while allowing full-service removal
-
(1x) PVC Valve Body – reinforced Schedule 80 housing for maximum strength and longevity
-
(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 movement and accurate seating
-
(1x) Stem O-Ring – seals the stem area to prevent internal leakage
-
(1x) Main O-Ring Seal (EPDM) – forms a durable barrier against backflow, UV wear, and mild chemical corrosion
How It Works
The valve operates through a gravity-assisted, pressure-driven ball mechanism:
-
Forward Flow (Open): System pressure lifts the internal ball, allowing water to pass freely.
-
Reverse Flow (Closed): When flow stops or reverses, the ball returns to its EPDM seat, forming a tight seal that prevents any backflow.
True Union Access: Union ends allow the valve to be removed for inspection, cleaning, or seal replacement—without cutting pipe or using special tools.
Why Choose a True Union Ball Check Valve?
-
Full Serviceability: Easily disassemble and maintain without disturbing the pipeline.
-
Zero Metal Parts: No springs or metal shafts to corrode—ensuring purity and longevity.
-
Quiet Operation: Soft-seating ball minimizes water hammer and flow noise.
-
High-Strength Construction: Schedule 80 PVC body provides excellent pressure resistance versus Schedule 40 alternatives.
-
Chemical Compatibility: EPDM seals resist fertilizers, chlorinated water, and mild acids.
