Product Details

A ‌Swing Check Valve‌ is a type of ‌check valve‌ designed to allow fluid flow in one direction while automatically preventing backflow (reverse flow). It operates using a hinged disc (or "flapper") that swings open or closed in response to fluid dynamics.

Technical Standard:
1.Design Standard: DIN 3202
2.Face to face: DIN 3202.
3.Flange Standard: EN1092-1.
4.Test Standard: GB/T 13927/API 598.

Product Advantages&Our Service:
1.‌Disc:‌ A disc or door-shaped element that seals against the valve seat.
2.‌Hinge Pin:‌ A pivot point allowing the disc to swing freely.
3.‌Valve Body:‌ Typically flanged (bolted).
4.‌Seat:‌ Precision-machined surface where the disc seals to block reverse flow.
5.Low Pressure Drop:‌ Disc retracts completely into the valve body, creating an unobstructed flow path → ideal for high-flow/low-head-loss applications.
6.‌Suitable for Large Pipe Sizes:‌ Preferred for pipelines ≥2 inches (DN50) due to simple scaling.
7.‌Handles Slurries/Viscous Fluids:‌ Less prone to clogging vs. dual plate valves; tolerates suspended solids better.
8.‌Simple & Robust:‌ Fewer moving parts → low maintenance and high reliability.
9.Adopt epoxy painting,stronger adhesion and good weather resistance.
10.Pressure Testing Report,3.1 Certificate of Material can be provided.
