1 in. SCH-80 PVC True Union Ball Check Valve Socket-Type ASTM D2466/F1970 One-Way Flow Control

The 247Garden 1-Inch Schedule-80 PVC True Union Ball Check Valve Socket-Type is designed for medium-flow systems that require dependable one-way flow control, long-term durability, and easy serviceability. Perfect for irrigation networks, hydroponic and aquaponic systems, laboratory fluid transfer lines, or aquarium return plumbing, this valve provides reliable backflow prevention with minimal pressure loss and no risk of corrosion.

Engineered with a true union design, this valve allows quick installation and full disassembly without cutting into your plumbing. Constructed from industrial-strength Schedule 80 PVC and fitted with EPDM seals, the 1-inch valve handles higher pressures than Schedule 40 alternatives, making it suitable for residential, commercial, and light industrial applications.

Product Specifications:

• Nominal Size: 1 inch

• Connection Type: Socket/Slip (solvent-weld)

• Material: Gray Schedule 80 PVC (UPVC-PW)

• Seal Material: EPDM (ethylene propylene diene monomer) for superior 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 proper flow and pressure

9-Piece Assembly Breakdown:

• (2x) Schedule 80 PVC Socket End Connectors – solvent-weld ends for strong pipe integration

• (2x) Union Nuts – secure the valve body while allowing full service access

• (1x) PVC Valve Body – reinforced with thick Schedule 80 walls for strength and durability

• (1x) Sealing Ball – precision-molded PVC ball lifts under forward flow, seals against reverse flow

• (1x) Gland (Ball Retainer) – keeps the ball centered for consistent operation

• (1x) Stem O-Ring – prevents leakage through the stem area

• (1x) Main O-Ring Seal (EPDM) – ensures a tight seal against backflow and resists wear and chemicals

How It Works:

• Forward Flow (Open): Fluid pressure lifts the ball, allowing unrestricted flow.

• Reverse Flow (Closed): The ball drops back into its EPDM seat, forming a leak-free seal.

• True Union Design: Union nuts allow removal of the valve body for cleaning, seal replacement, or inspection without cutting into pipe.

Why Choose a True Union Ball Check Valve?

• Serviceable Design: Easy to disassemble and maintain without altering plumbing.

• No Metal Components: Eliminates corrosion, ensuring water purity.

• Quiet Operation: Soft-seated ball prevents noise and water hammer.

• Heavy-Duty Build: Schedule 80 PVC ensures higher strength and pressure tolerance.

• Chemical Compatibility: Resistant to fertilizers, chlorinated water, and mild chemicals.

Applications:

• Irrigation manifolds

• Hydroponic and aquaponic systems

• Laboratory and industrial fluid transfer

• Water purification and filter loops

• Aquarium water return systems

• Fertilizer and chemical dosing lines

• Pump bypass and recirculation
