Check Valves

Check Valves – Multi Valve Corp

Check Valves, also known as non‑return valves, are designed to allow fluid to flow in one direction while automatically preventing reverse flow. They are critical for protecting pumps, compressors, and pipelines from backflow damage. At Multi Valve Corp, our Check Valves are precision engineered to deliver dependable performance across industries such as oil & gas, petrochemical, power generation, and chemical processing.

Performance & Reliability

  • Optimized Flow Efficiency – streamlined passages minimize pressure loss.

  • Reliable Backflow Prevention – engineered sealing ensures safe operation.

  • Durable Construction – built to withstand high pressure and corrosive environments.

  • Self‑Actuating Design – responds automatically to flow conditions, no external power required.

  • Quality Assurance – tested to meet API, ASME, and ISO standards.

 

Swing Check Valves

Featuring a hinged internal disc, the Swing Check Valve provides a low‑resistance path for forward flow. The disc swings closed automatically when flow stops or reverses, offering a mechanical fail‑safe without external actuation.

Mini Specs

Size Range: 1/2″ – 36″

Pressure Classes: ASME 150# – 2500#

Piston Check Valves

Utilizing a spring‑loaded piston or disc, this valve reacts instantly to changes in flow velocity. It is ideal for high‑pressure systems or applications where flow direction changes rapidly.

Mini Specs

Size Range: 1/2″ – 16″

Pressure Classes: ASME 150# – 2500#

Material Engineering

Our Check Valves are manufactured from premium cast steel, forged steel, and stainless steel, ensuring resilience against corrosion, high pressure, and extreme temperatures. Each valve undergoes strict inspection and testing to guarantee long‑term reliability in demanding industrial environments.
