Features

A corrosion-resistant stainless steel non-return valve with flanged connections, designed to prevent backflow in aggressive chemical and fluid systems.

✅Premium Stainless Steel Body: Casting conforms to ASTM A351 CF8/CF8M standards, providing exceptional resistance to rust, oxidation, and corrosive chemical media.

✅Low Flow Resistance: The full-port swing disc design allows the valve to open fully with minimal flow obstruction, ensuring high flow capacity and low pressure loss.

✅Automatic Backflow Prevention: Relying on gravity and medium back-pressure, the disc closes instantly when flow stops, protecting pumps and upstream equipment from water hammer and reversal damage.

✅Secure Flanged Ends: Equipped with standard flanges (ANSI/DIN/JIS) for rigid installation, ensuring a tight seal even under pipeline vibration.

✅Versatile Sealing Options: Available with metal-to-metal or soft seals (PTFE/Viton) to suit various temperature ranges and medium requirements.
