Carbon Steel Spring Check Valve – Wafer‑Type

This spring‑assisted wafer‑type check valve built in carbon steel offers fast closure and minimal reverse flow risk in compact installations. The spring mechanism helps protect against back‑flow or water hammer, making it ideal for varied industrial systems.

Technical Data:

• Body material: Carbon steel (A216 WCB or equivalent)

• Disc: Carbon Steel

• Mechanism: Internal coil spring supporting the disc closure — offers quicker response than gravity only swing types.

• Seat/trim: Typically metal or soft‑seat variant depending on application; NBR/EPDM soft versions available for water service.

• Connection: Wafer body designed to sit between flanges PN6/10/16/25 & ANSI 150

• Pressure rating: PN25 2" to 8", PN16 10"

• Temperature range: –10 °C to +120 °C or more depending on seat/trim.

• Sizes: Suitable for small to medium bore ranges, e.g., DN50–DN200.

Key Features:

• The internal spring enables faster disc closing to reduce water‑hammer risk in pump shutdowns or variable flow situations.

• Wafer format offers compact fit and easier retrofits between existing flanges.

• Carbon steel body provides strength for moderate industrial service while keeping material cost controlled.

• Ideal for systems where disc closure speed and reverse flow prevention are priorities.

Typical Applications:

• Pump discharge lines in industrial plants where rapid closure is beneficial.

• Compressed air or gas lines with risk of reverse flow.

• Water circulation or cooling loops where dynamic flow conditions exist.

Summary:
This wafer‑type carbon steel spring check valve addresses the need for a fast‑acting, compact non‑return solution in industrial systems. It delivers structural strength, quick response and versatile installation format.
