247Garden 2-Inch PVC True Union Ball Check Valve – Socket-Type | Heavy-Duty Backflow Prevention for Irrigation, Pools, Plumbing, and Aquatic Systems - ASTM D2466/F1970 Standard

Upgrade your water management system with 247Garden's Professional 2-Inch PVC True Union Ball Check Valve Socket-Type — a precision-engineered solution for preventing backflow and protecting your system from pressure damage, contamination, or reverse siphoning. Designed for durability, efficiency, and ease of maintenance, this high-performance check valve is built to meet the needs of both commercial and residential applications in irrigation, aquaculture, water features, hydroponics, pools, spas, and general plumbing.

Product Features:

• Size: 2-inch nominal

• Connection Type: Socket/Slip (solvent weld)

• Material: Rigid white Schedule 40 PVC

• Seal Material: EPDM for reliable chemical resistance and sealing

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

• Maximum Pressure Rating: Up to 150 PSI (non-shock at 73°F)

• Flow Direction: Single-direction vertical or horizontal installation

• Maintenance-Friendly Design: True union ends for easy removal and servicing

What's Included (9-Part Assembly):

1. 2x PVC End Connectors (Socket-Type): Easily solvent-weld into your existing PVC pipe system.

2. 2x Union Nuts: Allow the valve body to be disconnected without cutting pipe, ensuring fast maintenance or replacement.

3. 1x Stem O-Ring: Provides sealing around the internal stem area to prevent leakage and maintain system pressure.

4. 1x PVC Valve Body: Reinforced for structural integrity and long-term durability in demanding flow environments.

5. 1x Internal Ball: Precision-fit ball designed to automatically seal against reverse flow with minimal pressure drop.

6. 1x Gland (Ball Retainer): Holds the ball in place and helps guide its motion for smooth operation.

7. 1x EPDM O-Ring Seal: Provides a tight, chemical-resistant seal between the valve body and union ends.

Why a True Union Ball Check Valve Is the Best in the Market:

The 247Garden True Union Ball Check Valve offers a superior combination of reliability, serviceability, and flow efficiency that sets it apart from traditional spring check valves, swing checks, or wafer-style designs:

• ASTM D2466/F1970 Certified: Designed to meet strict dimensional and performance standards for professional plumbing systems.

• True Union Design: Both ends of the valve are removable, allowing for quick access to internal components without having to disassemble or cut any piping — a critical advantage for systems that require routine inspections or part replacements.

• Ball Mechanism: The ball check design uses gravity and fluid pressure to seal and open the valve. When water flows in the correct direction, the ball is pushed upward, allowing free flow. When flow reverses, the ball seats against the O-ring seal, preventing backflow with minimal turbulence.

• No Springs or Metal Parts: Unlike spring-loaded or metal-based check valves, this all-PVC model has no components that corrode or wear prematurely, making it perfect for chlorinated water, saltwater systems, and chemical solutions.

• Quiet and Low Resistance: With no flapping or banging like a swing check, the ball valve operates silently and reduces water hammer issues.

• EPDM Seals: Ideal for a wide range of water-based applications, EPDM offers excellent durability, chemical resistance, and long-term performance.

How It Works:

1. Forward Flow (Open Position): When fluid enters from the inlet side, pressure lifts the internal ball upward off its seat, allowing water to pass through the valve body.

2. Reverse Flow (Closed Position): When pressure drops or reverses, gravity (or back pressure) causes the ball to fall into the seat, where it seals tightly against the EPDM O-ring, blocking any reverse flow and protecting the upstream system.

3. Servicing: To access the ball or seals, simply unscrew the union nuts and remove the valve body. This is ideal for cleaning, replacing the ball, or inspecting the O-rings — all without disturbing your pipe system.

Applications:

• Greenhouse irrigation systems

• Hydroponics and aquaponics
