Cast steel gate valve with bypass valve, cast steel flange hard seal

The opening/closing component of the Z41H national standard gate valve is a gate disc, whose movement direction is perpendicular to the fluid direction. The gate valve can only be fully opened or fully closed, and cannot be used for regulation or throttling.

Main Advantages of Gate Valves:

• Unobstructed flow channel with low fluid resistance.
• Small opening/closing torque.

Main Disadvantages of Gate Valves:

• Sealing surfaces are prone to abrasion.
• Long opening/closing time.
• Large size and weight.

Cast iron rising stem gate valves are suitable for a wide range of temperatures, pressures, and diameters, and are widely used in industries such as chemical engineering, petroleum, metallurgy, gas, electric power, drainage, light textiles, and construction.
