Butterfly Valve

Design Features

• Wafer-type butterfly valve designed for installation between flanges.

• Operated with a lever handle (quarter-turn operation).

• Compact and lightweight construction for easy installation.

• Suitable for both on/off and throttling applications.

• Resilient-seated design for bubble-tight shutoff.

• Bi-directional sealing (can handle flow in either direction).

• Disc rotates within the valve body, minimizing pressure drop.

• Low torque operation reduces wear on sealing surfaces.

Cast Iron Butterfly Valve

Material of Construction

• Body made from cast iron, providing durability and strength.

• Disc typically made from stainless steel or nickel-plated ductile iron for corrosion resistance.

• Seat liner made from EPDM, NBR, or Viton depending on application requirements.

• Shaft/stem made from stainless steel for corrosion resistance and strength.

• Lever handle constructed from carbon steel or stainless steel, with locking mechanism.

• Fasteners typically stainless steel or zinc-coated steel.

Size Range Available

• Commonly available in sizes from 2 inches to 24 inches (DN50 to DN600).

• Larger sizes can be provided upon request for specific industrial requirements.

Pressure Rating

• Typically rated for PN10/PN16 (10 to 16 bar or 145 to 232 PSI).

• ANSI Class 150 equivalent.

• Suitable for temperatures generally ranging from -10°C to +120°C, depending on seat material.

Cast Steel Butterfly Valve

Design Features

• Wafer-type butterfly valve suitable for bi-directional flow.

• Quick 90-degree lever operation for open/close function.

• Compact and lightweight design reduces space and installation costs.

• Suitable for throttling and on/off applications.

• Precision-machined disc ensures minimal torque and superior sealing.

• Lockable lever handle for secure positioning.

• Designed for compatibility with international flange standards (e.g., ANSI, DIN, JIS).

Material of Construction

• Body: Cast Steel (e.g., ASTM A216 WCB) – strong and suitable for high-pressure applications.

• Disc: Stainless Steel (e.g., SS304/SS316) – corrosion-resistant and durable.

• Seat/Liner: EPDM, NBR, or Viton – selected based on media compatibility and temperature range.

• Stem/Shaft: Stainless Steel – high tensile strength and corrosion resistance.

• Handle: Carbon steel or ductile iron with powder coating – durable and corrosion-protected.

• Fasteners: Stainless steel or zinc-coated steel – ensures structural integrity and resistance to corrosion.

Size Range Available

• Typically available in sizes from 2 inches to 24 inches (DN50 to DN600).

• Larger sizes can be provided upon request for specific industrial requirements.

Pressure Rating

• Commonly rated at PN10/PN16 or ANSI Class 150.

• Suitable for working pressures up to 16 bar (232 PSI).

• Operating temperature range generally from -10°C to +200°C, depending on seat material.

Design Features

• Wafer-type butterfly valve for compact installation between flanges.

• Quarter-turn operation with lever handle for fast open/close control.

• Locking mechanism in the handle for secure positioning.

• Designed for both on/off and throttling service.

• Low torque operation due to precise disc alignment and high-quality sealing.

• Suitable for corrosive and hygienic applications (e.g., chemicals, food, pharmaceuticals).

• Compatible with international flange standards (ANSI, DIN, JIS).

Stainless Steel Butterfly Valve

Material of Construction

• Body: Stainless Steel (e.g., ASTM A351 CF8/CF8M) – high corrosion resistance and strength.

• Disc: Stainless Steel (e.g., SS304 or SS316) – offers excellent chemical and corrosion resistance.

• Seat/Liner: EPDM, Viton, or PTFE – selected for compatibility with different media and temperature ranges.

• Shaft/Stem: Stainless Steel – durable and resistant to rust and corrosion.

• Handle: Epoxy-coated carbon steel or stainless steel – corrosion-protected, ergonomic.

• Fasteners: Stainless Steel – for superior resistance in harsh environments.

Size Range Available

• Typically available in sizes from 2 inches to 24 inches (DN50 to DN600).

• Larger sizes can be provided upon request for specific industrial requirements.

Pressure Rating

• Commonly rated for PN10/PN16 or ANSI Class 150.

• Maximum working pressure: up to 16 bar (232 PSI).

• Operating temperature range: -10°C to +200°C, depending on seat material used.
