Underground Non-Rising Stem Wedge Gate Valve (Iron) DN450–DN800

Description

The Underground Non-Rising Stem Wedge Gate Valve (Iron) DN450–DN800 is a large-diameter non-rising stem gate valve engineered for trunk water mains. Its heavy-duty iron body, wedge gate and gear-assisted operation allow reliable isolation of large pipelines with manageable operating torque, while the buried-service design permits operation from the surface.

Technical Specifications:

• Pressure Class: PN10 / PN16
• Size Range: DN450 – DN800
