Extended rod steel low pressure gate valve
Designed with an extended stem structure, this steel low-pressure gate valve allows convenient operation in underground, insulated, or elevated pipeline systems. Manufactured from high-quality carbon steel or stainless steel, it offers excellent sealing performance, corrosion resistance, low flow resistance, and long-term reliability for industrial fluid control applications.
Extended rod steel low pressure gate valve
The Extended Rod Steel Low Pressure Gate Valve is specifically designed for installations where the operating point is difficult to access, such as buried pipelines, underground chambers, insulated pipelines, and elevated systems. The extended stem enables operators to control the valve from ground level or designated access points.
The valve adopts a wedge gate design that ensures full-bore flow with minimal pressure loss. Its robust steel construction provides excellent mechanical strength, corrosion resistance, and long service life under low-pressure working conditions.
Our extended rod gate valves can be supplied with complete international certifications:
