Professional Valve Manufacturer | Integrated Manufacturing
We select high-quality raw materials according to product specifications and international standards. All incoming materials are carefully inspected to ensure chemical composition, mechanical properties and traceability.
fire hydrant valve surfaces are professionally shot blasted to remove rust, scale and impurities. by epoxy powder coating, red fire‑retardant painting or hot‑dip galvanizing for long‑term anti‑corrosion performance.
What is the difference compare with signal butterfly valve?
This version has no signal feedback switch, cannot transmit electric signal to fire control cabinet.
Can this butterfly valve be used for flow adjustment?
Only for full‑open / full‑close isolation, throttling regulating service is prohibited.
What are the advantages of grooved connection?
No welding required, fast installation, convenient disassembly for maintenance.
