Butterfly Valves

Product Description

Crescent Valves manufactures a comprehensive range of Butterfly Valves in sizes from 2″ to 60″ (DN 50 to DN 1500) and Pressure Rating from 150# to 300#, engineered to deliver reliable flow control and shut-off performance in a wide range of industrial applications.

These valves are available in various combinations of size, pressure class, materials of construction, seating options, and end connections to meet the specific requirements of different process plants and operating conditions.

Crescent Butterfly Valves are offered in Centric (Concentric), Double Offset, and Triple Offset configurations to suit varied service conditions:

• Centric (Concentric) Design: Features a resilient soft seat and is ideal for general-purpose applications, providing bubble-tight sealing and easy operation in low-pressure systems.
• Double Offset Design: Incorporates a slightly eccentric shaft and disc arrangement, minimizing friction between the disc and seat, enhancing durability, and allowing operation in higher pressure and temperature services.
• Triple Offset Design: Employs a metal-to-metal sealing system with triple eccentricity for critical and severe service conditions, ensuring zero leakage, extended service life, and suitability for high-temperature, high-pressure, and corrosive applications.

The valves are available with Soft Seats (EPDM, NBR, PTFE, DEVLON) and Metal Seated options, including Extended Stem designs for insulated or underground piping systems.
