1 Inch PVC Gate Valve with Viton O-Ring

This Spears 2031-010 gate valve provides positive shut-off for irrigation and cold water systems. The nonrising stem design suits installations where vertical space is limited. It is constructed from PVC with a Viton O-ring for chemical resistance. NSF certification confirms suitability for potable water use.

Installing the FNPT threaded connections

The valve uses FNPT threads on both inlet and outlet for straightforward connection to compatible piping. A screwed bonnet allows access for maintenance if required. Ensure threads are properly sealed to prevent leaks at the rated 200 psi pressure. Over-tightening PVC threads can cause cracking, so apply appropriate torque during assembly.

Pressure and temperature limits for PVC construction

The valve is rated for 200 psi at 73 F with a maximum operating temperature of 140 F. PVC material properties dictate that pressure capacity decreases as temperature rises above the reference point. The polypropylene wedge and handwheel share similar thermal limits. Do not exceed the stated temperature threshold in service.

Questions about this item

How can I confirm the 1 inch FNPT Spears gate valve is working correctly after installation?

Pressurise the line up to 200 psi at 73 F and verify zero leakage past the Viton O-ring and polypropylene wedge; the non-rising stem should move smoothly through the full open-close range.

What components come with the 2031-010 valve and what must I source separately?

The valve body, Viton O-ring, PVC non-rising stem, polypropylene wedge and handwheel are supplied assembled; you must provide 1 inch FNPT pipe fittings and thread sealant.

Which version of the Spears 2031-010 should I choose for a potable water system rated to 140 F?

This single model is NSF certified for potable water, handles 200 psi at 73 F and a maximum temperature of 140 F, so it covers the stated requirement without alternative versions.
