Check Valves

Product Description

Crescent Valves manufactures a comprehensive range of Swing Type Check Valves in sizes from 2″ to 40″ (DN 50 to DN 1000) and pressure ratings from 150# to 2500#, designed to ensure unidirectional flow and prevent backflow in various process applications.

These valves are available in multiple combinations of size, pressure class, materials of construction, and end connections to suit diverse industrial requirements.

Crescent Swing Check Valves feature a one-piece disc construction, securely fastened to the hinge by a lock nut and pin, allowing the disc to rotate freely to minimize localized wear. The hinge pin is designed for excellent wear resistance, ensuring long-term reliability.

The valves are offered in Standard Bolted Bonnet as well as Pressure Seal designs to accommodate high-pressure and high-temperature applications, providing tight sealing and robust performance.

Crescent Swing Check Valves deliver durable, reliable, and low-maintenance performance, ensuring efficient backflow prevention in critical industrial systems.

Product Description

Crescent Valves manufactures a comprehensive range of Dual Plate Check Valves in sizes from 2″ to 24″ (DN 50 to DN 600) and pressure ratings from 150# to 1500#, designed to ensure unidirectional flow and prevent backflow in various process applications.

These valves are available in multiple combinations of size, pressure class, materials of construction, and end connections to meet the requirements of diverse industrial environments.

Crescent Dual Plate Check Valves feature two spring-loaded plates mounted on a central hinge, providing quick closure to prevent reverse flow. This design ensures minimal pressure drop, reduces water hammer, and delivers reliable operation in demanding conditions.

Constructed from a wide range of durable materials, these valves are suitable for high-cycle, high-pressure, and corrosive service applications. Their compact design allows for easy installation and maintenance, making them ideal for oil and gas, chemical, power, and petrochemical industries.

Product Description

Crescent Valves manufactures a comprehensive range of Spring-Loaded Piston Check Valves in sizes from 1/2″ to 2″ (DN 15 to DN 50) and pressure ratings from 150# to 2500#, designed to ensure unidirectional flow and prevent backflow in high-pressure and high-temperature applications.

These valves are engineered for rapid response and reliable shut-off, making them ideal for steam, oil, gas, chemical, and petrochemical industries. They are available in various combinations of size, pressure class, materials of construction, and end connections to meet a wide range of plant and process requirements.

Crescent Spring-Loaded Piston Check Valves feature a spring-loaded disc, which ensures automatic closure when flow reverses, providing tight sealing, reduced water hammer, and smooth operation. This design ensures minimal pressure drop and long-term reliability even in high-pressure, high-temperature, or corrosive environments.
