Butterfly Valves

Metal butterfly valves corrode, pit, and fail fast in corrosive water lines, turning simple isolation points into costly callbacks for your customers. SOVAL’s NSF-certified PVC butterfly valves resist that breakdown, giving distributors a valve line that handles potable water systems without the maintenance headaches bronze and iron create. SOVAL stocks these valves in wafer configurations from 2 inches through 8 inches, so they ship fast and hold up through years of daily use in municipal, commercial, and residential water systems.

Types of PVC Butterfly Valves We Carry

SOVAL stocks the 585 Series PVC Wafer Butterfly Valves, covering irrigation, plumbing, and utility flow control projects in a single general-purpose valve, giving distributors a straightforward match for most incoming orders.

Valve Specifications & Sizing

PVC Wafer Butterfly Valves vs. Lug Style

A PVC wafer butterfly valve sits between two pipe flanges with no bolt holes of its own; the flange bolts running through both sides of the pipeline hold the valve in place. 

A lug-style valve swaps that open gap for threaded lugs cast into the body, so each side of the line bolts on independently. That difference shows up most during maintenance: a crew can unbolt one side of a lug valve to pull a downstream filter housing or service a dead-end branch while the other side of the line stays pressurized and in service. Try that with a wafer-style valve, and the whole section depressurizes, since removing either flange releases both sides at once. 

SOVAL’s PVC wafer valves cover the majority of potable water and utility jobs where a full shutdown during service is routine, and for projects that call for lug-style bolt-through convenience, the 842 Series Cast Iron Lug Style Butterfly Valve fills that gap.

Common Applications for Our NSF PVC Butterfly Valves

NSF-certified PVC butterfly valves handle isolation and flow control anywhere potable water needs to stay safe for human contact. Distributors stock these valves most often for jobs like:

• Plumbing risers and shutoff points in commercial and residential buildings
• Municipal water distribution mains and hydrant isolation valves
• Irrigation mainlines tied into a potable water supply
• Potable water pump stations and booster systems
• Food and beverage processing lines requiring sanitary water contact
• Cooling tower makeup water drawn from a potable source
