Design features

1. Gate valve 30nzh41nz belongs to cast shut-off valves with a wedge gate. The wedge gate blocks the flow of the medium perpendicularly to direction of the working medium's movement.
2. Manual operation is carried out through wheel. When the wheel is turned, the torque is transmitted to the stem, which raises or lowers the wedge, opening or closing the passage section.
3. Stem extends when the valve is opened, which requires additional height space during installation.
4. Gate valve has a flanged connection.

Gate valves 30nzh41nz are widely used in the following industries:

1. Oil and Gas Industry: For controlling the flow of oil, gas, and oil products.
2. Chemical Industry: For handling aggressive chemical substances.
