Adjustable PVC Relief Valve

The Hayward Flow Control RV1100TE is a 1-inch FNPT relief valve built from PVC with an EPDM seat and a stainless-steel spring. It suits plumbing systems that require pressure protection in a corrosion-resistant body. Installers working with water treatment or chemical feed lines will find the materials compatible with typical service fluids. The valve ships new and ready for direct installation.

Pressure Range and Temperature Limits

The valve operates across an adjustable range of 5 to 75 psi and arrives with a factory setting of 25 psi. Service temperatures are rated from 40 to 140 degrees Fahrenheit, so the part is not suited for steam or high-temperature process lines. Both inlet and outlet use 1-inch FNPT threads, limiting connection options to matching female fittings. The test lever is not included, so manual testing requires a separate tool.

ASTM D1784 Compliance

The body and disc meet ASTM D1784 for PVC compound quality, confirming the material standard for pressure-rated piping components. Buyers who need a different pressure class, a larger port size or a valve with an integrated test lever must select another model. The fixed 1-inch FNPT ends also rule out installations that demand flanged or solvent-weld connections.

Questions about this item

Should I pick the 25 psi factory setting or adjust it within the 5 to 75 psi range?

The valve ships set at 25 psi and can be adjusted anywhere between 5 and 75 psi to match your system’s required relief pressure.

What does the 5 to 75 psi range mean once the valve is installed?

The valve will begin to open at the chosen set point and relieve excess pressure up to the 75 psi maximum, protecting downstream piping and equipment.

How does the ASTM D1784 standard relate to the valve’s pressure rating?

ASTM D1784 certifies the PVC body material; the valve’s own adjustable 5 to 75 psi range determines the actual pressure limit in service.
