Product overview:
Wedge gate valve is suitable for cutting off or connecting pipeline media in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries with nominal pressure PN1.6~16MPa and working temperature -29~350℃. Bellows gate valve has reasonable structure, reliable sealing, excellent performance, and beautiful appearance; the sealing surface is welded with Co-based hard alloy, which is wear-resistant, corrosion-resistant, and has good anti-friction performance and long service life; the bellows gate valve stem is tempered and surface nitrided, which has good anti-corrosion and anti-friction performance; double sealing, more reliable performance; the valve stem lifting position indication is more intuitive.
