Product Introduction：

Cast iron gate valves are shut-off valves that use a gate as the opening and closing element. 

The gate's movement direction is perpendicular to the fluid, resulting in low flow resistance and allowing bidirectional flow of the medium. 

They are relatively tall and have a long opening and closing time. 

They are divided into two types: wedge type (including single-gate, double-gate, and resilient-gate types) and parallel-gate type (including single-gate and double-gate types). 

Based on the stem structure, they are classified as rising stem gate valves (exposed stem thread for easy lubrication) and non-rising stem gate valves (internal thread, stem only rotates). 

Valve body materials include gray cast iron, carbon steel, and stainless steel. 

They use flange connections, with nominal diameters ranging from DN40 to DN1200, and are suitable for pipelines in industries such as water, steam, oil, petrochemicals, pharmaceuticals, and power generation.

Features:

1.Bronze trim hard sealing surface, working temperature up to 200℃.

2.Cast iron body, cost-effective for heating and general utility pipelines.

3.Rising stem (Z41T): visible valve position; 

   Non-rising stem (Z45T) for limited installation space.

4.Full bore structure, low flow resistance, bi-directional flow.

5.Optional electric actuator for automatic control.
