Solenoid Valve for 1/2 in CPVC Systems

The Hayward SV20050STV is a normally closed, 2-way inline solenoid valve built for 1/2 inch CPVC piping. It operates on 120V AC power and uses an FPM seal for chemical compatibility. The coil enclosure is watertight and supplied without a junction box. This component suits pool and spa automation circuits requiring reliable on-off control.

Flow Capacity and Pressure Limits

The valve carries a Cv rating of 2.3 through a 3/8 inch orifice, indicating the flow volume available under standard test conditions. Maximum operating pressure differentials for air, inert gas, fuel gas and fuel oil are not rated or not applicable per the manufacturer data. Installers must verify that system pressures stay within safe, unpublished limits for the specific media used. It is not suited for applications demanding documented pressure ratings.

CPVC Construction and Watertight Coil

The body is moulded from CPVC, offering resistance to corrosion and many pool chemicals. The FPM seal material supports durability in chlorinated or brominated water. A watertight coil enclosure protects the 120V AC windings from moisture without an integral junction box, so wiring connections must be made in a separate, code-compliant enclosure. The inline, single-body design simplifies placement in straight pipe runs.

Questions about this item

Will the SV20050STV 120VAC CPVC solenoid valve connect to my existing 1/2 in CPVC plumbing?

The valve body is CPVC with 1/2 in nominal pipe size and 3/8 in orifice, designed for inline solvent-weld connections to matching CPVC pipe and fittings.

How can I verify the valve is operating correctly after installation?

Apply 120V AC power; the normally closed valve should open, allowing flow with a Cv of 2.3, and close tightly with FPM seals when power is removed.

What components are included with the SV20050STV and what must I source separately?

The valve assembly is supplied without a junction box; you will need CPVC solvent cement, compatible pipe, fittings, and a suitable 120V AC power supply.
