The Extended Stem Cast Steel Gate Valve is a specialized type of gate valve designed for applications where the valve needs to be installed in hard-to-reach or insulated locations. It features an extended stem that allows the valve to be operated from a distance, making it ideal for use in buried pipelines, high-temperature environments, or systems with thick insulation.

Key Features:
-
Material:
-
Body Material: Made from high-quality cast steel (e.g., WCB, WCC, LCB, or other grades), providing excellent strength, durability, and resistance to high pressure and temperature.
-
Seat and Disc: Typically made from stainless steel or other corrosion-resistant materials, ensuring tight sealing and long service life.
-
-
Extended Stem:
-
The valve features an extended stem that raises the handwheel or actuator above the pipeline, allowing for easy operation even when the valve is buried, insulated, or located in hard-to-reach areas.
-
The stem extension length can be customized based on application requirements.
-
-
Gate Valve Design:
-
The valve uses a wedge or parallel gate mechanism to control flow, providing a tight seal and minimal pressure drop when fully open.
-
Suitable for both isolation and throttling applications.
-
-
Operation:
-
Can be operated manually (via handwheel or gear operator) or automatically (via electric, pneumatic, or hydraulic actuators).
-
The extended stem ensures smooth operation even in challenging environments.
-
-
