Ball Valves
Product Description
Crescent Valves manufactures a comprehensive range of Trunnion Mounted Ball Valves in sizes from 2″ to 40″ (DN 50 to DN 1000) and pressure ratings from Class 150# to 2500#, designed to deliver reliable flow control and tight shut-off in a wide range of process applications.
These valves are available in various combinations of sizes, pressure classes, materials of construction, and end connections to meet the specific requirements of industries such as oil & gas, petrochemical, chemical, and power plants.
Crescent Trunnion Mounted Ball Valves are offered in both full-bore and reduced-bore designs, providing flexibility for different flow and process conditions. The trunnion-mounted design reduces operating torque, ensures enhanced durability, and maintains tight sealing under high-pressure and high-temperature conditions.
Crescent Trunnion Mounted Ball Valves are engineered to provide optimal performance, durability, and safety in demanding industrial processes

Product Description
Crescent Valves manufactures a comprehensive range of Floating Type Ball Valves in sizes up to 8″ (DN 200) and pressure ratings from Class 150# to 2500#, designed for reliable flow control and tight shut-off in various process industries.
These valves are available in multiple combinations of sizes, pressure classes, materials of construction, and end connections to meet the specific requirements of chemical, petrochemical, oil & gas, and power plant applications.
The floating-ball design allows the ball to move slightly towards the downstream seat under line pressure, ensuring bubble-tight sealing and consistent performance. Crescent Floating Ball Valves are offered in both full-bore and reduced-bore configurations, with a wide selection of materials and end connections to suit customer-specific process requirements.
Crescent Floating Ball Valves combine durability, ease of operation, and reliable sealing performance, making them ideal for a broad range of industrial processes
