Butterfly Valves
SOVAL supplies non-NSF PVC wafer butterfly valves for process water, chemical, and industrial lines that never carry drinking water, at a lower cost than NSF-certified alternatives. The wafer-style body installs between flanges in a fraction of the space a lug or full-flange valve needs, cutting installation time on tight retrofit jobs.
Wholesale distributors purchase these valves in volume from SOVAL's inventory for wastewater treatment, irrigation, and HVAC systems, with pressure ratings built for continuous industrial duty.
Non-NSF PVC Wafer Butterfly Valve Construction & Specifications
A non-NSF PVC wafer butterfly valve controls flow with a quarter-turn disc that rotates on a stainless steel stem running through the pipeline instead of a separate valve body. Skipping NSF/ANSI 61 certification lets SOVAL match seat and seal materials to chemical and process compatibility rather than drinking-water compliance rules. Distributors pair this flexibility with SOVAL's non-NSF PVC check valves, which SOVAL stocks for the same wastewater and process accounts.
| Feature | Specification |
|---|---|
| Body and Disc | Precision-molded PVC that resists corrosion in chemical and wastewater lines |
| Seat | EPDM or FKM (Viton) material matched to fluid compatibility, not NSF/ANSI 61 potable listing |
| Stem | Stainless steel construction for consistent quarter-turn actuation |
| End Connections | Wafer-style profile that fits between ANSI Class 125/150 flanges without a separate bolt pattern |
| Size Range | 2 inches through 12 inches |
| Pressure Rating | Up to 150 PSI at 73°F |
| Actuation | Lever handle standard, gear operator option for larger diameters |
Wafer-Style Design Built for Non-Potable & Process Water Service
A wafer-style non-NSF PVC butterfly valve sits between two pipeline flanges without its own bolt pattern, so the flange bolts hold the valve and pipe together. This design saves space and weight compared to lug- or flanged-body valves, which matters in tight retrofit runs in non-potable and process water systems such as wastewater plants, cooling towers, and chemical feed lines.
Distributors serving accounts that need drinking-water compliance should stock SOVAL's NSF-certified PVC butterfly valves instead, built on the same wafer profile with NSF/ANSI 61 listing added.
Applications for Non-NSF PVC Wafer Butterfly Valves
Non-NSF PVC wafer butterfly valves cover process lines where drinking-water certification never enters the spec. Wholesale buyers request them most often to isolate or throttle flow in non-potable water and corrosive fluid systems running at moderate pressure and ambient temperature.
Top applications for non-NSF PVC wafer butterfly valves include:
- Industrial process water and manufacturing plant piping
- Water treatment plant backwash and filtration lines
- Irrigation mainlines and agricultural water distribution
- Aquaculture and aquarium life support systems
- Mining and mineral processing water circuits
- Marine and shipboard piping systems

A wafer valve fits between two flanges using the pipe's own bolts, while a lug-style valve has threaded inserts that let one side of the line stay pressurized when the other side comes apart for service.
Yes, the valve's ISO 5211 mounting pad accepts pneumatic and electric actuators for remote or automated operation.
PVC construction holds up for continuous service to about 140°F, with pressure capacity dropping as the fluid temperature climbs above ambient.
Yes, SOVAL ships by the pallet or container load with no minimum order beyond standard case packs, so wholesale accounts stay stocked without gaps.
