Spears s1580-20f Pvc Spring Check Valve 2 Inch Fpt

Product Description

The SPEARS s1580-20f is a spring-loaded check valve constructed from PVC with EPDM seals, designed to allow one-directional fluid flow and prevent backflow in pressurized piping systems. The valve features female pipe thread (FPT) connections on both ends and a white finish consistent with Schedule 80 PVC fittings. At 2 inches nominal size, it is suited for mid-range residential and light commercial plumbing, irrigation, and chemical handling lines. Licensed plumbers and pipefitters are the typical installers. The spring-loaded design provides positive shut-off without relying solely on gravity or flow pressure, making it effective in horizontal, vertical, and angled pipe runs.

This check valve is commonly used in potable water distribution, pool and spa circulation, irrigation systems, and chemical feed lines where PVC is the specified pipe material. The EPDM seal material offers compatibility with a broad range of water-based fluids and mild chemicals. It is appropriate for both residential and light commercial installations where non-metallic corrosion-resistant components are required by specification or environment.

Key Features

• PVC body construction resists corrosion and is compatible with a wide range of water-based and mild chemical fluids
• Spring-loaded mechanism enables reliable backflow prevention in horizontal, vertical, and angled orientations
• EPDM seals provide good resistance to water, ozone, and mild chemical exposure
• 2-inch FPT connections for straightforward threaded installation into standard pipe systems
• White color finish consistent with standard PVC piping components

Compatibility

Designed as an OEM-style replacement or new-installation component for 2-inch FPT threaded PVC piping systems in plumbing, irrigation, pool, and chemical handling applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Depressurize and drain the line completely before removing any existing valve or fitting. Apply thread sealant tape or compound rated for PVC and the fluid being conveyed; do not overtighten FPT connections, as PVC threads can crack under excessive torque. Verify correct flow direction indicated on the valve body before completing installation.
