Buy Gate Valve Z43DY PN16–PN25 Cast Steel Flanged Manual Operated

The Z43DY Gate Valve by VALVEHU is a robust industrial solution engineered for reliable shut-off in high-pressure fluid systems. Designed in compliance with GB/T9124.1-2019 and GB12221-2005 standards, this wedge gate valve offers dependable performance across oil, water, steam, and natural gas applications. Available in pressure classes PN16 and PN25, it accommodates nominal diameters ranging from DN40 to DN1000, making it suitable for various pipeline sizes and system demands.

This flanged end gate valve is constructed from high-quality cast steel, providing excellent mechanical strength and thermal durability. It features a rising stem mechanism and is manually operated via a heavy-duty handwheel, which ensures visible position indication and precise control over flow shut-off. The valve seat is designed to provide tight sealing with minimal leakage under both high and low-pressure conditions.

Its guided wedge design (for the DF model) enhances seat alignment, reduces torque requirements, and minimizes wear on sealing surfaces. It also ensures long-lasting reliability even in demanding thermal cycling environments. With an operating temperature range from -29°C to 121°C, this valve is suitable for diverse industrial processes.

Whether you’re managing a water supply system, refining operation, power generation facility, or chemical processing line, this gate valve offers the strength and dependability you require.
