Cycle Stop Valves CSV1A Cycle Stop Valve 1 in Ss 25 Gpm

Product Description

The CYCLE STOP VALVES CSV1A is a constant pressure valve designed to regulate flow and maintain system pressure in water pump applications. Built from stainless steel with a molded thermoplastic spring cage, this valve is rated for flows from 1 to 25 GPM and is field-adjustable across a pressure range of 15 psi to 150 psi. The 1-inch body size fits standard residential and light commercial pump systems. Licensed plumbers and pump system technicians install this valve to eliminate pump short-cycling, extend pump life, and maintain consistent downstream pressure without a variable frequency drive.

The CSV1A is used in residential and light commercial well pump systems where constant pressure is required across varying demand conditions. It installs on the discharge side of a submersible or above-ground pump and acts as a pressure-sustaining and flow-control valve simultaneously. The valve body includes three additional ports - two at 1/2 inch and one at 3/4 inch - allowing it to serve as a pressure tank manifold, consolidating connections at a single fitting point. This makes it well suited for retrofits where manifold simplification is a priority.

Key Features

• Stainless steel valve body for corrosion resistance in potable water service
• Molded thermoplastic spring cage reduces weight and resists corrosion
• Field-adjustable pressure setting from 15 psi to 150 psi
• Rated for flow rates from 1 to 25 GPM
• Three additional ports (two at 1/2 inch, one at 3/4 inch) for manifold use
• 1-inch main connection size fits standard pump discharge plumbing

Compatibility

Designed as an OEM-style constant pressure valve for residential and light commercial well pump systems with discharge flow up to 25 GPM and system pressures between 15 psi and 150 psi.

Installation Notes

Installation is performed by a licensed plumber or pump system technician. Shut off and lock out the pump and relieve all system pressure before making any connections. Install the valve on the pump discharge line in the correct flow direction as indicated on the valve body. Local plumbing codes under the IPC may apply; verify requirements before final installation.
