U Type Butterfly Valves Made in Tianjin China
U Type Butterfly Valves with a compact, short-body design that fits between flanges for medium- and low-pressure pipeline isolation, featuring wormgear or pin actuation for manual operation.
U Type Butterfly Valves Available From Stock Drawings
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 operators managing pipeline isolation in tight spaces
- Power plant maintenance teams needing reliable manual valves for auxiliary systems
- Petrochemical and chemical plant engineers specifying valves for low- to medium-pressure service
- Marine and shipyard builders installing valves in confined engine room or piping areas
- Pharmaceutical and metallurgical facility engineers requiring consistent valve performance
What It Fixes on the Line
- Existing flange spacing does not allow room for gate valves or long-body valves
- Manual operation on large-diameter valves requires excessive torque with standard handwheels
- Valves with loose disc connections fail under repeated cycling or pressure surges
- Different valve types across a system require multiple spare parts and maintenance procedures
- Buyers need a single source for both standard and large-diameter valves across multiple industrial applications

U Type Butterfly Valves FAQ
What is the difference between U Type and wafer butterfly valves?
U Type valves have a longer body with a central hub and are designed for flange-to-flange installation with a central mounting point. They are not wafer-style and require specific flange alignment.
Can the U Type Butterfly Valve be operated manually with a wormgear?
Yes. Models with wormgear actuation are available for manual operation, providing mechanical advantage for larger diameters.
What sizes and pressures are available in this series?
The U Type Butterfly Valve 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.
Is a PTFE seat available for aggressive media?
Yes. PTFE seat variants are offered for media that attack rubber. Provide the medium type and operating conditions for confirmation.
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 are issued on request.
Can I order mixed models in one shipment?
Yes. U Type Butterfly Valves, gate valves, check valves, and other families can be combined in a single container for project delivery.
