Threaded Lug Wafer Butterfly Valve (Centerline Type, Stainless Steel Plate)
Product Introduction
The Threaded Lug Wafer Butterfly Valve (Centerline Type) features a stainless steel plate stamped body and a centerline disc design, ensuring minimal flow resistance and reliable sealing performance. Designed for compact piping systems, its threaded lug structure allows direct bolting between pipeline flanges, enabling quick installation and space-saving benefits. Ideal for water treatment, HVAC, and food & beverage industries, especially in applications requiring frequent operation or confined spaces.
Product Advantages
- Easy Installation: Threaded lug design simplifies assembly, reducing time and labor costs.
- Low Flow Resistance: Centerline disc minimizes pressure drop, improving system efficiency.
- Low Maintenance: Gasket-free design, only requiring periodic stem lubrication.
- ISO9001 Certified: Strict quality control ensures consistent performance and reliability.
Product Features
Centerline Disc Design
- Symmetrical disc and stem alignment reduces flow resistance, improving efficiency (high Cv value).
- Suitable for low to medium pressure (PN10-PN16), ensuring smooth operation with low torque.
01
Threaded Lug Structure
- Internal threads on lugs engage directly with flange bolts, enhancing installation speed and eliminating nut loss risks.
- Even load distribution prevents valve body deformation from uneven tightening.
02
Stamped Stainless Steel Body
- Precision-stamped from 304/316 stainless steel plates, eliminating weld seams and corrosion risks.
- High strength, lightweight, and corrosion-resistant, compatible with water, air, oil, and more.
03
Soft Seat Seal
- Seats made of PTFE or EPDM ensure zero leakage, wear resistance, and long service life.
- Complies with food-grade standards (e.g., FDA), suitable for potable water and food processing.
