SUPMEA Pneumatic PVC Wafer Butterfly Valve

Description

SUPMEA Pneumatic PVC Wafer Butterfly Valve

Corrosion‑Resistant Flow Control for Industrial Service.
For industries that deal with corrosive fluids, wastewater treatment, chemical plants, or processes involving strong acids or bases, choosing the right valve material is crucial. The SUPMEA Pneumatic PVC Wafer Butterfly Valve delivers reliable, automated flow control with excellent chemical resistance and economical performance. This valve is engineered to combine the low cost and chemical resilience of PVC with the speed and automation of pneumatic actuation in a compact wafer design.

Advantages

Excellent Corrosion Resistance
PVC is highly resistant to many acids, bases, and chemicals. Using PVC body and proper seals reduces risks of corrosion and chemical damage compared to metallic valves in certain environments.
Lightweight & Cost-Effective
PVC valves are much lighter than metal counterparts. Wafer style reduces material and installation cost. Pneumatic actuation, though requiring air supply, often costs less in explosive or corrosive environments where electric actuation may require more protection or maintenance.
Fast & Automated Operation
Pneumatic actuators enable quick opening/closing, enabling automation, remote control, and integration with control systems (e.g. PLCs). This improves process safety and responsiveness.
Compact, Slim Wafer Design
Wafer butterfly valves are designed to be installed between two flanges, minimizing the face-to-face dimension (length of the valve), saving space. This design is especially advantageous where pipe layout constraints exist.
Low Maintenance & Reliable Sealing
Fewer metal components in the flow path means less risk of rust or scaling. Proper seal material (EPDM, FKM, etc.) ensures tight shutoff. Wafer style seats are easier to access for replacement when needed.

Typical Specifications (Expected / Comparative)

Parameter	Typical Values / Range
Body Material	PVC or UPVC (UV‑stabilized), possibly reinforced body to resist deformation.
Disc / Shaft Material	Stainless steel stem/shaft; disc often PVC or reinforced plastic; sometimes SS or other corrosion‑resistant metals.
Seat / Seal Material	EPDM, FKM (Viton), Buna‑N etc., depending on chemical compatibility.
Actuation Type	Pneumatic actuator (double acting or spring return) mounted to the wafer valve (ISO 5211 standard in many cases).
Pressure Rating	Typically up to ~10 bar (≈150 psi) for smaller sizes; larger diameters somewhat lower.
Temperature Range	Roughly 0‑60 °C for PVC body; depending on seal material maybe somewhat higher or restricted by media.
Size Range	DN50 to perhaps DN200 or larger, depending on supplier and actuator capability.
