Model codes as they appear on our production drawings. Sizes and pressure ratings for each code are confirmed on quotation.
Buyers This Category Suits
- Water and wastewater treatment plant engineers specifying isolation valves for pump discharge and mainline control
- Power plant maintenance teams replacing valves in auxiliary systems with limited face-to-face space
- Chemical and pharmaceutical plants needing reliable shut-off with minimal leakage in process lines
- Marine engineers installing valves in shipboard piping where vibration and space constraints are critical
- Project procurement managers sourcing a single supplier for multiple valve types across a plant scope
What It Fixes on the Line
- Existing flanged connections require a valve with precise flange alignment and bolt hole matching
- Gate valves are too heavy and long for tight spaces between flanges in retrofit or compact systems
- Standard butterfly valves lack the sealing integrity needed for pressure retention in water and chemical service
- Valves with poor eccentricity design suffer from high torque and premature seat wear under repeated operation
- Multiple suppliers for different valve types increase inventory complexity and reduce procurement efficiency
Why Engineers Specify This Family
Advantage
Double eccentric design reduces seat contact stress and wear, extending service life under frequent operation
Advantage
Flanged ends match standard pipe flanges, ensuring secure, leak-free connections without additional fittings
Advantage
Resilient seat provides tight shutoff and low operating torque, suitable for water and general industrial media
Advantage
Available with wormgear or electric actuators for remote or automated control, tested before shipment
Advantage
Nominal diameter range from DN10 to DN2600 covers small branch lines to large mainline applications
Advantage
Manufactured in a single facility under ISO 9001 and ISO 14001 systems, ensuring consistent quality across models
Where These Valves Are Installed
- Isolating feedwater lines in boiler auxiliary systems within power generation plants
- Controlling flow in chemical process headers where tight shutoff and low torque are required
- Managing water supply in district heating networks with moderate pressure and frequent cycling
- Securing discharge lines on sewage pumping stations with flanged pipe connections
- Integrating valves into marine piping systems where vibration resistance and compact design are essential
Eccentric Flanged Butterfly Valves FAQ
What is the difference between eccentric and concentric butterfly valves?
Double eccentric valves have an offset disc and shaft, reducing seat wear and enabling tighter shutoff under pressure. Concentric valves have no offset and are suited for lower pressure and less demanding service.
Can the valve be supplied with an actuator?
Yes. Wormgear and electric actuators are available and fitted, adjusted, and tested at the factory before shipment.
What sizes and pressures are available?
The series covers nominal diameters from DN10 to DN2600 mm and nominal pressures from 0.05 to 4.0 MPa. Exact size and pressure per model are confirmed on request.
What material is used for the seat?
The standard seat is resilient rubber. For aggressive media, PTFE or coated disc options may be available. Send the medium details and we confirm suitability.
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 I order mixed valve types in one shipment?
Yes. Butterfly valves, gate valves, check valves, joints, and strainers from the same range can be combined in one container for project delivery.
