Who It Is For

Buyers This Category Suits

  • Water treatment plant operators needing automatic backflow protection in pump stations
  • Power plant engineers installing check valves in feedwater and condensate lines
  • Petrochemical and chemical plant designers specifying non-return valves for process piping
  • Marine engineers requiring corrosion-resistant check valves for bilge and ballast systems
  • HVAC and heating system builders installing check valves in low-pressure return lines
Problems Solved

What It Fixes on the Line

  • Backflow in pump discharge lines causes pump damage and system instability
  • Manual isolation valves are not practical for automatic backflow prevention
  • Valves with loose or unsealed discs fail to close under low pressure or during power loss
  • Inconsistent disc movement across different valve brands leads to uneven wear and premature failure
  • Lack of standardised sizing and pressure ratings across suppliers complicates procurement and spares management
Advantages

Why Engineers Specify This Family

Automatic operation

Automatic operation: closes without external input when flow reverses, ensuring system safety

Advantage

Dual plate design in wafer type models provides balanced closing force and reduced slamming

Advantage

Wide nominal diameter range from DN10 to DN2600 allows use across small and large systems

Advantage

Nominal pressure range from 0.05 to 4.0 MPa covers medium and low-pressure applications

Advantage

Manufactured under ISO 9001 and ISO 14001 systems, ensuring consistent quality and process control

Advantage

All models are designed and produced in-house, enabling full traceability and consistent material sourcing

Application Scenarios

Where These Valves Are Installed

  • Preventing backflow in municipal water pump discharge lines after pump shutdown
  • Protecting feedwater pumps in power plants from reverse flow during turbine trips
  • Stopping reverse flow in chemical process lines where contamination must be avoided
  • Ensuring one-way flow in heating system return lines to maintain thermal efficiency
  • Securing ballast and bilge systems on ships where accidental backflow could compromise safety

FAQ

Check Valves FAQ

What types of check valves are available?

We offer wafer type dual plate check valves, flanged type check valves, and foot valves. The exact model and configuration are confirmed on request.

Can I get a check valve with a specific pressure rating?

Yes. Our check valves are rated from 0.05 to 4.0 MPa. The exact pressure rating for a given model is confirmed on quotation.

What sizes are available?

The nominal diameter range is DN10 to DN2600. The exact size availability per model is confirmed on request.

Are the valves certified?

Yes. Tianjin MIC Valve Co., Ltd. holds ISO 9001 quality management and ISO 14001 environmental management system certification.

Can I order mixed models in one shipment?

Yes. Check valves, butterfly valves, gate valves, strainers, and joints can be combined in one container for project delivery.

Do you supply valves with actuated or manual operators?

No. Check valves are designed for automatic non-return operation. Actuators are not available as standard or optional.
