Butterfly Valve Manufacturers - PTFE Lined Lugged and Tapped Butterfly Valve

Product Features:

Dual-Purpose Lugged & Tapped End Connections  

Lugged Design: Integrates threaded inserts for direct bolt-through piping attachment without full flanges – ideal for end-of-line service or frequent disassembly.  

Tapped Holes: Permits secure bolting between ANSI/DIN/JIS flanges, eliminating the need for through-bolts across the valve body.  

Zero-Pipeline-Distortion: Distributes stress evenly during installation, preventing misalignment in high-vibration systems.

Precision-Engineered for Reliability

Isolated 17-4PH Stainless Steel Shaft: Prevents media contact, eliminating galvanic corrosion.  

Fire-Safe Design (API 607): Optional metal secondary seal contains media during PTFE failure.  

Low-Torque Operation: PTFE-encapsulated disc reduces actuation force by 40% vs. metal-seated valves.
