Description

Flanged Butterfly Valve – Overview

The flanged butterfly valve is a quarter-turn valve designed for reliable flow regulation and shut-off in pipelines carrying water, air, gas, oil, and other media. Its disc rotates on a central axis, providing quick operation and minimal pressure drop. With a flanged connection on both ends, it offers secure installation and easy maintenance for a wide range of industrial applications.

Key Design Features

Flanged End Connection
Conforms to ASME, DIN, EN, or JIS flange standards for secure, leak-proof pipeline integration.
Quarter-Turn Operation
0° to 90° disc rotation allows for fast opening and closing with precise throttling control.
Disc & Seat Design
- Streamlined disc minimizes flow resistance.
- Resilient or metal seat options to suit various temperature and pressure conditions.
Actuation Options
- Manual (lever or gear-operated)
- Pneumatic, electric, or hydraulic actuators for automated control systems.
Materials
- Body: Ductile iron, carbon steel, stainless steel.
- Disc: Stainless steel, ductile iron, or coated alloys.
- Seat: EPDM, NBR, PTFE, or metal sealing.

Applications

Water Treatment & Distribution – Isolation and control in municipal and industrial water systems.
HVAC & Building Services – Regulating chilled water and hot water flow.
Oil & Gas – Suitable for non-corrosive and mildly corrosive hydrocarbon service.
Chemical Processing – Handling compatible chemicals and process media.

API Standard Swing Check Valve

API Standard Swing Check Valve – Overview An API standard swing check valve is a non-return valve designed in accordance with the American Petroleum Institute’s (API) specifications, ensuring consistent quality, performance, and safety across a range of industrial applications. This valve type automatically prevents backflow by utilizing a swinging disc mechanism that opens under forward flow and closes when flow reverses, protecting pumps, compressors, and piping systems. Key Design Features API Compliance Manufactured to API 6D or API 594 standards for precise dimensional accuracy, performance reliability, and compatibility with global pipeline systems. Swing Disc Mechanism The hinged disc swings away from the seat during forward flow and returns to the closed position under reverse flow or gravity. Material Options Available in carbon steel, stainless steel, alloy steel, or duplex materials to suit various pressure, temperature, and corrosive environments. End Connections Flanged, butt weld, and socket weld ends for seamless integration into pipeline networks. Pressure and Temperature ...
