View SpecificationBuyers This Category Suits
- Water and wastewater treatment plant operators needing reliable non-return protection
- Power plant engineers installing check valves in feedwater and condensate lines
- Petrochemical and chemical plant designers specifying backflow prevention in process headers
- Marine engineers fitting check valves in shipboard piping systems with limited space
- HVAC and heating system builders requiring compact, automatic non-return valves
What It Fixes on the Line
- Backflow in water and process lines causes contamination or system damage when pumps stop or pressure drops
- Existing check valves fail due to disc flutter or seat wear under variable flow conditions
- Space constraints between flanges prevent the use of traditional swing check valves with long pivoting arms
- Mixed valve brands across a system lead to inconsistent disc and seat materials, complicating maintenance
- Lack of standardisation in dual plate check valves results in long lead times for replacement parts
Why Engineers Specify This Family
Face-to-face length
Face-to-face length: the wafer body adds minimal length between flanges, ideal for tight installations
Automatic operation
Automatic operation: no operator, handle, lever or actuator required; valves open and close by flow reversal
Dual disc design
Dual disc design: two plates move independently to reduce slamming and flutter under varying flow rates
Material variety
Material variety: available in carbon steel, stainless steel, CF8, and al bronze discs to match media and pressure
Standardised body
Standardised body: the same body design supports multiple disc materials and sizes across the DN10 to DN2600 range
Single source
Single source: all components including discs, seats and bodies are manufactured in the same Tianjin facility under ISO 9001 and ISO 14001
Where These Valves Are Installed
- Preventing backflow in municipal water supply lines after pump shutdown
- Protecting feedwater pumps in power generation systems from reverse flow during turbine trips
- Stopping reverse flow in chemical process headers where contamination must be avoided
- Ensuring unidirectional flow in shipboard ballast and bilge systems
- Maintaining pressure integrity in district heating circuits during system cycling

Wafer Type Dual Plate Check Valves FAQ
Can a wafer type dual plate check valve be used in a dead-end pipe run?
No. A wafer body must clamp between two pipe flanges. For dead-end service, use a lug type or a pipe-end check valve with a threaded or welded end.
What materials are available for the discs and body?
Discs are available in carbon steel, stainless steel, CF8, and al bronze. Bodies are available in carbon steel and stainless steel. The exact material for a model is confirmed on request.
What sizes and pressures are available?
The nominal diameter range is DN10 to DN2600 mm, and the nominal pressure range is 0.05 to 4.0 MPa. The exact size and pressure rating per model code are confirmed on quotation.
Do you offer custom disc materials for aggressive media?
Yes. For corrosive or high-temperature media, specify the medium and operating conditions. We confirm suitable disc and seat materials based on the application.
What certifications does the factory hold?
Tianjin MIC Valve Co., Ltd. holds ISO 9001 quality management and ISO 14001 environmental management certification. Test records for your order are issued on request.
Can multiple valve types be shipped together in one container?
Yes. Butterfly valves, gate valves, check valves, joints, and strainers can be combined in a single container, which is standard for project orders.
Is the valve tested before shipment?
Yes. Each valve undergoes functional and pressure testing at the factory before packing. Test records are available on request.
