The 247Garden 3/4-Inch Schedule-80 PVC True Union Ball Check Valve Socket-Type is built for medium-diameter systems where dependable backflow prevention and long-term durability are essential. Whether used in irrigation networks, hydroponic systems, laboratory fluid loops, or aquarium return lines, this high-performance check valve ensures one-way flow protection with minimal pressure drop and zero corrosion risk.
With its true union construction, this valve allows for fast installation and complete service disassembly without cutting pipe. Made from heavy-duty Schedule 80 PVC with EPDM seals, the 3/4-inch valve offers higher pressure handling than Schedule 40 options, making it suitable for residential, commercial, and light industrial systems.
Product Specifications:
-
Nominal Size: 3/4 inch
-
Connection Type: Socket/Slip (solvent-weld)
-
Material: Gray Schedule 80 PVC (UPVC-PW)
-
Seal Material: EPDM (ethylene propylene diene monomer) for chemical resistance
-
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 adequate flow
9-Piece Assembly Breakdown:
-
(2x) Schedule 80 PVC Socket End Connectors – solvent-weld ends for easy integration
-
(2x) Union Nuts – secure the valve body and allow full disassembly
-
(1x) PVC Valve Body – Schedule 80 reinforced housing for strength and longevity
-
(1x) Sealing Ball – precision-molded PVC ball for smooth and accurate flow control
-
(1x) Gland (Ball Retainer) – stabilizes the ball’s travel path
-
(1x) Stem O-Ring – internal seal preventing leakage
-
(1x) Main O-Ring Seal (EPDM) – resilient seat for tight closure against backflow
How It Works:
-
Forward Flow (Open): System pressure lifts the internal ball, allowing unobstructed flow.
-
Reverse Flow (Closed): Ball returns to its EPDM seat, sealing tightly to block backflow.
-
True Union Serviceability: Easily disassemble with union nuts for cleaning, inspection, or seal replacement without cutting into your plumbing.
Why Choose a True Union Ball Check Valve?
-
Service-Friendly: Full internal access for inspection and maintenance.
-
No Metal Parts: 100% PVC and EPDM construction prevents corrosion.
-
Quiet Performance: Soft ball seating reduces water hammer and noise.
-
Stronger Build: Schedule 80 PVC withstands higher pressure than Schedule 40.
-
Chemical Resistance: Safe for fertilizers, chlorinated water, and mild chemicals.
Applications:
-
Irrigation manifolds
-
Hydroponic and aquaponic systems
-
Laboratory fluid transfer systems
-
Water purification loops
-
Aquarium return and overflow systems
-
