1-1/2 in. PVC True Union Ball Check Valve Socket-Type ASTM D2466/F1970 Professional One-Way Flow Control Fitting

247Garden 1-1/2-Inch PVC True Union Ball Check Valve – Socket-Type | ASTM D2466/F1970 Compliant | Professional-Grade One-Way Flow Control Valve for Irrigation, Plumbing, Filtration, and Aquatic Systems

The 247Garden 1-1/2-Inch PVC True Union Ball Check Valve Socket-Type is a heavy-duty, professional-grade one-way flow control fitting designed for large-volume water systems requiring precise backflow prevention. Manufactured in compliance with ASTM D2466 (fittings) and ASTM F1970 (valves), this valve delivers powerful performance, exceptional reliability, and total inline serviceability in irrigation, aquaculture, pool, spa, and industrial plumbing applications.

Built from high-quality Schedule 40 PVC and sealed with durable EPDM elastomers, this valve uses a free-floating internal ball to prevent reverse flow. Its true union design features removable end connections secured by union nuts, allowing you to service or replace the valve body without cutting any pipe. Engineered for consistent, leak-free operation, the 1-1/2" valve is ideal for systems requiring dependable backflow control, easy maintenance, and resistance to chemical and environmental exposure.

Technical Specifications:

• Nominal Size: 1-1/2 inch

• Connection Type: Socket/Slip (solvent-weld for Schedule 40 PVC)

• Valve Type: Ball check valve, true union

• Material: Rigid white Schedule 40 PVC w/ EPDM O-Ring Seal

• Seal Material: EPDM (resistant to UV, chlorine, fertilizers, mild acids)

• Standards Compliance: ASTM D2466 (fittings), ASTM F1970 (valves)

• Max Operating Pressure: 150 PSI at 73°F (non-shock)

• Temperature Range: 33°F to 140°F

• Flow Direction: One-way only (inlet to outlet)

• Orientation: Vertical preferred; horizontal acceptable with sufficient flow pressure

9-Piece Construction:

1. (2x) PVC End Connectors (Socket-Type): Allow solvent welding into any 1-1/2" Schedule 40 PVC pipe.

2. (2x) Union Nuts: Threaded rings that connect the valve body to the end connectors. Enable full removal for inline maintenance.

3. (1x) Central Valve Body: Precision-molded PVC housing designed for high flow rates and pressure stability.

4. (1x) Free-Floating PVC Ball: The core check mechanism, designed to rise during forward flow and drop into a sealed seat during reverse flow.

5. (1x) Gland (Ball Retainer): Guides the ball’s travel, ensures proper sealing alignment, and reduces wear.

6. (1x) Stem O-Ring: Internal seal that prevents leaks through the stem or central axis.

7. (1x) EPDM Seat O-Ring: Sits at the base of the valve body to create a reliable backflow seal against the ball.

How the Valve Works:

• Forward Flow (Open): Water enters from the inlet side, pushing the internal ball upward, allowing full flow through the valve.

• Reverse Flow (Closed): If pressure drops or flow reverses, the ball falls into the EPDM seat, instantly blocking the passage to prevent contamination or siphoning.

• Maintenance: Simply unscrew the union nuts and remove the valve body for internal inspection or cleaning. No pipe cutting or system shutdown is required.
