The unique double-flange design simplifies installation, eliminates gasket misalignment, and distributes pipeline stress evenly. Tested to 1.5x PN pressure with zero leakage, our valves outperform conventional models with 40% lower operating torque.

1.Zero-Leakage Seal: Full-rubber resilient seat (EPDM/NBR/Viton(FKM)/PTFE(Teflon)) ensures bubble-tight shutoff even at low pressures.
2.Corrosion Defense: Ductile iron body with epoxy coating (350μm) + 316 SS disc resists pitting, scaling, and electrolytic corrosion.
3.Bi-Directional Flow: Symmetric disc design handles reverse flow without performance loss.
4.Fire-Safe Option: provide metal seat + graphite seals.
5.Certified Reliability: CE PED 2014/68/EU | UKCA | WRAS | ACS | ISO 9001:2015

Selecting the right butterfly valve for your system is a crucial decision that can affect the performance and longevity of your piping network.
The Bare Shaft Double Flanged Butterfly Valve provides a fundamental and versatile flow control solution designed for seamless integration with any actuation system. Featuring an unfinished shaft extension and robust double-flanged construction, this valve serves as the ideal core component for customized automation across water, HVAC, and industrial processing applications.
The Wafer Type Soft Rubber Lined Butterfly Valve provides an economical and efficient solution for water treatment, irrigation systems, and general industrial services where reliable bubble-tight sealing and minimal maintenance are essential. This valve features a resilient rubber-lined design that ensures excellent sealing performance while maintaining a compact and lightweight profile for easy installation between pipeline flanges.
The PTFE Seat & PFA Coated CF8 Disc Butterfly Valve represents a premium solution for handling the most aggressive chemical media and ultra-pure processes. This valve combines a PTFE seat with a PFA-coated CF8 (SS304) stainless steel disc, creating an unparalleled barrier against corrosion, contamination, and chemical attack in critical industrial applications.
Choosing the right lug butterfly valve is key for safe, leak-free operation. Gaskets play a vital role in maintaining tight seals under varying pressures and temperatures.
