Rising Stem Gate Valves

The Hanno Valve high-quality Rising Stem Gate Valve is suitable for a variety of demanding environments. It is specifically designed for systems requiring frequent operation or where an intuitive understanding of the valve’s status is vital—such as fire protection, water supply, and drainage systems.

The distinguishing feature of the Hanno Valve Rising Stem Gate Valve is its external stem. This design ensures that the threads are not in contact with the fluid, preventing corrosion and allowing for easy lubrication and observation.

KEY ADVANTAGES OF HANNO VALVE SOLUTIONS

Visual Operational Status: Because the stem rises and lowers, operators can determine the valve's position at a glance, which is a safety requirement in many fire-safety protocols.

Ease of Automation: The exposed stem design makes it highly convenient to add additional driving mechanisms, such as electric actuators or pneumatic devices, for remote control integration.

Enhanced Lever Force: Hanno Valve engineering ensures these valves provide greater leverage, making them significantly easier to open and close compared to standard designs.

Superior Sealing: Most of our gate valves utilize forced sealing, where external mechanical force ensures the gate plate is pressed firmly against the seat for a leak-proof finish.

TECHNICAL CHARACTERISTICS & DESIGN

Mechanical Operation

The valve stem moves linearly alongside the gate plate. Using high-precision trapezoidal threads, the nut at the top of the Hanno Valve assembly converts rotational torque into powerful linear thrust.

Gate Plate Engineering

The gate moves perpendicular to the fluid direction. Note that these valves are designed to be fully opened or fully closed; they are not intended for throttling or flow adjustment.

Wedge Gate Design: The sealing surfaces form a wedge shape. The wedge angle is typically $5^{\circ}$ but can be adjusted to $2^{\circ}52'$ depending on the medium temperature.

Rigid vs. Elastic Gates:

Rigid Gate: A solid, one-piece construction for standard reliability.

Elastic Gate: Capable of slight deformation to compensate for sealing surface deviations and temperature fluctuations.

PRODUCT CLASSIFICATION

As a premier provider, Hanno Valve offers various configurations of Rising Stem Gate Valves to meet specific project needs:
