Achieving Optimal Flow Control: How SteadyLine Actuators Combat Water Hammer

Achieving Optimal Flow Control: How SteadyLine Actuators Combat Water Hammer

Water hammer poses significant risks in industrial flow control systems, causing potential damage to pipes, valves, and other components due to the sudden surge in pressure. This phenomenon occurs when valves open or close too quickly, creating a shock wave that travels through the fluid. The Kinetrol SteadyLine addresses this issue effectively by incorporating built-in dampening and adjustable opening and closing speeds.

By controlling the speed at which valves operate, the SteadyLine actuator reduces the abrupt changes in fluid velocity, thereby minimizing the pressure surges associated with water hammer. This capability ensures a smoother and more controlled flow, protecting the system from the harmful effects of sudden pressure spikes. Additionally, the built-in dampening feature further absorbs any residual shocks, providing an extra layer of protection and enhancing the longevity of the entire flow control system.

Implementing an actuator like the SteadyLine in industrial and commercial settings offers numerous advantages. It mitigates the risks associated with water hammer and contributes to the system's overall reliability and efficiency. Operators can fine-tune the actuator's performance to match the specific requirements of their application, ensuring optimal flow control and preventing damage that could lead to costly repairs or downtime. By integrating such advanced features, the SteadyLine actuator significantly enhances industrial flow control systems' safety, durability, and performance.

When reducing harmful shock or excessive motion or ensuring accurate and repeatable valve opening and closing times, Kinetrol Steadyline enhances valve stability, accuracy, and speed control.

Kinetrol Steadyline series precision valve actuators feature built-in damping devices that provide smooth resistance to actuator/valve shaft rotation, increasing with angular velocity. This product smooths out the actuator's standard travel, dampens pipeline flow-induced valve disc oscillations, and allows users to specify a minimum travel time during power failures.

The Steadyline Series: Kinetrol's Answer to Ultra-Reliable Valve Actuation with Enhanced Valve Damping Features

The Steadyline Series: Kinetrol's Answer to Ultra-Reliable Valve Actuation with Enhanced Valve Damping Features

Rapid opening or closing valves in industrial process piping systems can lead to several problems. Here's a rundown of potential issues:
  1. Water Hammer: This is one of the most commonly known problems resulting from the rapid closing or opening of valves. Also known as hydraulic shock, water hammer occurs when a fluid's flow rate changes, causing a sudden increase in pressure producing shock waves that travel through the fluid in the pipes. The resulting forces can damage pipes, valves, and other equipment.
  2. Cavitation: This occurs when the pressure of a liquid drops below its vapor pressure, leading to the formation of vapor bubbles. When these bubbles move to an area of higher pressure, they collapse, causing localized shock waves, eroding the valves and pipes' material, and leading to premature equipment failure.
  3. Surge Pressures: Similar to water hammer but typically in systems with gases, rapid valve closure or opening can result in a pressure surge, damaging the system.
  4. Pump Issues: Rapidly closing a valve downstream of a pump can result in a sudden increase in pressure, which might cause the pump to work against a "dead head" condition, leading to overheating and potential damage to the pump.
  5. Instrumentation Errors: Rapid changes in flow rates can cause instrumentation reading errors, as many flow meters and sensors require steady-state conditions for accurate measurements.
  6. Process Upsets: Rapid valve actions can lead to unexpected changes in process conditions, potentially affecting product quality or even causing unsafe conditions.
  7. Noise: Fluids' sudden acceleration or deceleration can create noise due to vibrations. Over time, this can also contribute to material fatigue.
  8. Seal and Gasket Failure: The sudden change in pressure and flow can exert excessive stress on seals and gaskets, leading to premature failure.
  9. Mechanical Stress: The physical stress from rapid valve actions can weaken pipe supports, joints, and valve mechanisms.
A dashpot is a mechanical device that resists motion, often viscous friction, to dampen dynamic systems. Essentially, a dashpot is a damper that uses hydraulic or viscous friction to absorb energy, similar to how shock absorbers work in cars to smooth the ride. A dashpot rotary damping unit refers explicitly to a device that provides rotational damping.

Kinetrol's Steadyline pneumatic actuator assemblies are precision valve actuators, integrating their dashpot rotary damping units to provide smooth resistance to actuator/valve shaft rotation and individual customer requirements.

Kinetrol Steadyline assemblies smooth out the actuator's standard travel, dampen any flow-induced valve disc oscillations, and allow the user to specify a minimum travel time upon power failure.

A New Standard of Valve Stability, Accuracy, and Speed Control

Kinetrol Steadyline

The Kinetrol Steadyline series are precision valve actuators with built-in damping devices that give smooth rotational resistance to the actuator/valve shaft. Water hammer occurs when a pipe's fluid flow changes rapidly. The effect may be high pipe pressures, mechanical stress on pipe structures, and potential flow reversal. If not controlled, it can cause pipe bursting, pipe breaking, and joint leakage. The Kinetrol Steadyline actuators smooth the actuator's standard travel. It dampens any pipeline flow-induced oscillations of the valve disks and enables the user to set a minimum amount of travel time on power failure. As a result, the Kinetrol Steadyline provides better performance, reduced downtime, and lower operating costs.

Kinetrol Steadyline Actuators Mitigate Water Hammer Damage from Pump Station


Water hammer occurs when a pipe's fluid flow changes rapidly. The effect may be high pipe pressures, mechanical stress on pipe structures, and potential flow reversal. If not controlled, it can cause pipe bursting, pipe breaking and joint leakage. Vane actuators open and close valves and can be tightly controlled with regards to opening and closing speeds. The Kinetrol Steadyline series are precision valve actuators with built-in damping devices providing a smooth resistance to shaft rotation which increases with angular velocity. The Kinetrol Steadyline product smooths out the normal travel, dampens any valve-flow induced disc oscillations, and provides a minimum user-specified amount of travel time on power failure.

A water treatment facility pump station was having recurring problems with a large hydraulic actuator that was very cumbersome and expensive to maintain. The well engineered solution was a Kinetrol Size 14 Steadyline double acting actuator with digital speed controllers installed on 12” Pratt butterfly valves. The result: better performance, reduced downtime, lower cost of operation.
