Lasco Slo-Close PVC True-Union Ball Valve, EPDM O-Ring

The Lasco Slo-Close PVC True-Union Ball Valve is a full-block valve designed for reliable flow control in irrigation, sprinkler, and general PVC piping systems. Its slow-close action reduces water hammer and delivers consistent, predictable shut-off for outdoor and utility use.

• True-union design allows easy removal of the valve body for maintenance without disturbing system piping.
• Slo-close mechanism provides controlled, gradual shut-off to minimize pressure surges and reduce system stress.
• Durable PVC construction resists corrosion and common outdoor exposures for long service life.
• EPDM O-ring seal offers reliable sealing against leaks and is compatible with typical irrigation chemicals and common site conditions.
• Available in multiple nominal sizes to fit standard PVC piping systems and sprinkler lines.

This valve is available in 1 in., 1-1/2 in., 2 in., and 3 in. variants to match prevailing pipe sizes. Install with standard PVC solvent-weld or compatible union fittings according to local plumbing codes; inspect seals occasionally and replace O-rings if signs of wear appear. For applications requiring specific pressure or temperature ratings, refer to technical data from Lasco or consult a plumbing professional to confirm suitability for your system.
