View SpecificationBuyers This Category Suits
- Water and wastewater treatment plant operators standardising on compact isolation valves
- Pump and skid system builders requiring short face-to-face length valves
- HVAC and fire protection contractors installing valves in tight mechanical spaces
- Industrial plant maintenance teams managing multiple valve types across one site
- EPC contractors sourcing medium- and low-pressure valves for water, heating and process scopes
What It Fixes on the Line
- Existing flange spacing is too short for gate valves or other long-body valves
- Valves with loose disc-to-stem connections fail under repeated cycling or pressure changes
- Mixed brands across a system lead to inconsistent spare parts and stocking challenges
- Small and mid-sized valves are often quoted as custom items with extended lead times
- Buyers need a single supplier capable of delivering a full range of valve types and sizes
Why Engineers Specify This Family
Advantage
Face-to-face length is minimised as the wafer body adds only a short section to the pipeline run
Advantage
Disc-to-stem connections are pinned or half-shaft designed to maintain alignment and torque transfer over cycles
Advantage
Resilient and PTFE seat options are available to suit clean water, raw water, and aggressive media
Advantage
The same body design supports manual levers, gearboxes, and pneumatic or electric actuators
Advantage
The product family covers DN10 to DN2600 across all types, enabling one-source procurement
Advantage
All valves are manufactured in the same Tianjin facility under ISO 9001 and ISO 14001 systems
Where These Valves Are Installed
- Isolating pump suction and discharge lines in municipal water and wastewater pumping stations
- Zone shut-off on fire protection and service water risers where flange spacing is limited
- Throttling control of cooling water return lines in power plant auxiliary systems
- Batch isolation on process water headers in chemical and pharmaceutical plants
- Balancing flow in district heating secondary circuits operating at low pressure
Industries and Guides for This Family
Water Supply and Drainage
Sectioning valves non-return protection and joints for distribution mains pumping stations and treatment works.
Power Generation
Cooling water circulating water and auxiliary system isolation for power station pipework.
Chemical Engineering
Corrosion resistant lined valves for aggressive media and process water headers.
Butterfly Valves FAQ
What is the difference between wafer and lug type butterfly valves?
A wafer body clamps between two flanges and requires a bolted connection across the pipe. A lug type has threaded lugs on each end, allowing one side to be removed while the other remains under pressure.
Which seat material is best for my application?
Resilient seats are suitable for clean and raw water. PTFE seats and coated discs are used for corrosive or aggressive media. Provide the medium, temperature, and concentration for confirmation.
What sizes and pressures are available in this family?
The series covers nominal diameters from DN10 to DN2600 mm and nominal pressures from 0.05 to 4.0 MPa. Exact size and pressure ratings per model are confirmed on request.
Can the valves be supplied with actuators fitted?
Yes. Levers, gearboxes, pneumatic, and electric actuators are fitted, adjusted, and tested at the factory before shipment.
What certifications does the factory hold?
Tianjin MIC Valve Co., Ltd. holds ISO 9001 quality management and ISO 14001 environmental management system certifications. Test records for your order are available on request.
Do you supply multiple valve types in one order?
Yes. Butterfly valves, gate valves, check valves, joints, and strainers can be combined in a single container shipment.
