Key Specifications / Features
Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Although they are available in a wide range of sizes and costs, check valves generally are simple, or inexpensive. Check valves work automatically and most are not controlled by a person or any external control.
Check valves are often used in steam lines, condensate lines, water lines, HVAC systems, and chemical feed pumps, to name just a few common applications. These valves are critical components in many situations, as reverse flow can be very damaging to some equipment. Therefore, it’s essential that the symptoms of check valve failure be detected as early as possible to prevent facility downtime and costly repairs.
A swing check valve is mounted with a disc that swings on a hinge or shaft. The disc swings off the seat to allow forward flow and when the flow is stopped, the disc swings back onto the seat to block reverse flow. The weight of the disc and the return flow has an impact on the shut-off characteristics of the valve.
Relia supplies a complete range of swing check valves with both internal and external hinge pin types. External control devices such as damping, locking, and manual override are part of Relia’s expertise. Size: NPS 1/2″~64″ (DN50~DN1600).
WCB (UNS Code J03002) is covered by ASTM A216 standard, which specification covers carbon steel castings for valves, and other pressure-containing parts for high temperature service and the quality required for assembly with other castings or wrought steel parts by fusion welding. WCB is for non corrosive service application from -29℃ to 425℃.
