1 in. PVC SCH-40 True Union Ball Check Valve Socket-Type ASTM D2466/F1970 One-Way Flow Control

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

Protect your water system with confidence using 247Garden’s 1-Inch PVC True Union Ball Check Valve – Socket-Type, a durable and serviceable one-way flow control valve engineered for long-term performance and backflow prevention. Ideal for both commercial and residential use, this valve is precision-manufactured to meet ASTM D2466 and ASTM F1970 standards and is built to function in a wide range of water applications, including irrigation systems, hydroponics, aquaculture, rainwater harvesting, swimming pools, and general plumbing systems.

This valve features a true union design for effortless installation and maintenance. The internal free-floating PVC ball prevents reverse flow by automatically seating when pressure reverses or siphoning occurs, helping protect your pump, pipes, and system from contamination and water hammer.

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

Why Choose a True Union Ball Check Valve from 247Garden?

Professional Design for Maximum Flow Control:
This valve uses a gravity-assisted ball mechanism that opens under forward pressure and seals tightly upon reverse flow, providing quiet and efficient operation without relying on metal springs or hinges.

True Union for Easy Maintenance:
Both ends of the valve are removable, making inspection, cleaning, or replacement simple without having to cut or rework surrounding pipe sections.

Corrosion-Free Construction:
All-plastic, non-metallic components mean no rust, no spring fatigue, and no worries in saltwater, chlorinated, or chemical-heavy systems.

Low Pressure Drop and Quiet Function:
The ball valve mechanism minimizes water hammer and turbulence, ensuring quiet, low-resistance flow in both light and high-demand applications.

Long-Lasting EPDM Seals:
EPDM is known for excellent durability and compatibility with a wide range of water-based and mildly corrosive liquids. Perfect for indoor and outdoor systems.

Typical Applications:

• Drip irrigation and sprinkler systems

• Hydroponic and aquaponic setups

• Rainwater collection and tank systems

• Swimming pool and spa plumbing

• Marine and freshwater aquariums

• Pond filtration and water features

• Water booster and circulation pumps

• General water flow control in residential and commercial plumbing

How It Works:

• Forward Flow: As water enters from the inlet, it lifts the internal ball, allowing full passage through the valve.

• Reverse Flow: When pressure drops or reverses, the ball settles into its seat, creating a watertight seal that blocks backflow.

• Servicing: Simply unscrew the union nuts, remove the valve body, and access the ball or seals—no pipe cutting, no system downtime.
