PVC butterfly valves are commonly used in industrial systems for their high levels of reliability and fast-acting shutoff capabilities. PVC butterfly valves are used in a variety of applications, such as agricultural irrigation systems, domestic water systems, chemical process applications, and liquid and gas processing applications. Unlike traditional metal valves, PVC butterfly valves have reduced pressure drop and minimal flow turbulence which makes them very efficient in terms of energy use. Size 50mm x 2" to 150mm x 6"

 PVC is also know as UPVC are manufactured from un-plasticized polyvinyl chloride polymer, maximum operating temperature of 60℃ (140F)   UPVC (Rigid polyvinyl chloride) offers an erosion and corrosion resistant material suitable for a variety of residential, commercial, and industrial valve uses. UPVC is lightweight yet rugged material that are rust-proof, making them perfect for use in many water applications. Valves made of UPVC are commonly used in chemical process...

Valves made of PVC are commonly used in chemical process, potable water, irrigation, water treatment and waste-water, landscaping, pool, pond, fire safety, brewing, and other food and beverage applications.
They are a good low-cost solution for most flow control needs.

Key Features:

• Material Options: PVC, UPVC, CPVC, PP, or PVDF

• Design Type: Wafer, Lug, or Flanged end connection

• Operation: Manual (lever handle), gear-operated, pneumatic, or electric actuator

• Disc Material: PVC / PP / PVDF / Stainless Steel (as per requirement)

• Seal Material: EPDM, NBR, or FKM for leak-proof sealing

• Size Range: 40 mm to 400 mm (1½” to 16”) or customized

• Pressure Rating: PN 10 / PN 16

Applications:

• Water treatment plants

• Irrigation and agricultural systems

• Chemical processing industries

• Food and beverage systems

• Wastewater management

• Acid and alkaline fluid handling

Advantages:

• Lightweight and easy to install

• Corrosion and chemical resistant

• Low maintenance and long service life

• Cost-effective alternative to metal valves

• Smooth operation with minimal torque requirement

• Compact design suitable for tight spaces

Working Principle:

When the handle or actuator turns the disc by 90°, the valve opens or closes the flow path.

• Open Position: The disc aligns with the flow direction, allowing full flow.

• Closed Position: The disc turns perpendicular to the flow, completely stopping it.

• Intermediate Positions: Used for throttling or regulating flow.
