[Case Study] Fundamental Measures Against Water Hammer

Adopting a special butterfly valve as a fundamental measure against water hammer!

At a steel manufacturing company, a cylinder valve was installed for flow adjustment in the factory's piping system. However, it has been reported that fine-tuning the valve opening is difficult, leading to the occurrence of water hammer, which damages the piping. They consulted us to see if there is a valve that can reduce the hammer. Issues: 1. The current cylinder valve makes it difficult to finely adjust the valve opening. (It goes from fully open to fully closed suddenly.) 2. They want to reduce water hammer and extend the lifespan of the piping. *Water hammer refers to a phenomenon, also known as water shock, that occurs when the flow of water in a pressurized pipe is suddenly stopped, causing a shock and high pressure to develop within the pipe due to the inertia of the water. When the water or steam in the piping is instantaneously halted, the kinetic energy of the fluid has nowhere to go and is converted into pressure energy, resulting in a rapid increase in pressure within the piping (pressure fluctuation) and the generation of a "high-pressure wave" (shock wave). This pressure wave can propagate instantaneously over long distances through the piping and fluid (in water, at speeds exceeding 1,400 meters per second), causing unusual noises (such as knocking sounds) in locations far from the source of the problem and potentially damaging the piping or valve body.

Teflon lining valve butterfly valve PFA/PTFE

Can be cleared in any harsh environment! Produced in a class 1000 clean room.

High corrosion resistance and durability The high corrosion resistance unique to Teflon (PTFE/PFA) and its properties that prevent fluid adhesion make it ideal for fluids such as strong acids, gases, and food. Additionally, its unique internal structure prevents fluid retention, ensuring even greater durability and cleanliness. Adoption of a new valve body seal structure A backup rubber is attached to the valve body. The compression reaction force of the rubber presses the outer edge of the valve body against the body seal. Furthermore, to enhance airtightness, the center of the body seal is subtly raised inward. By fitting the valve body snugly, the sealing capability is completely ensured. High heat and pressure resistance to withstand harsh environments Even under conditions of 150°C and 1.0 MPa, the sealing capability and operability remain unchanged. With high heat resistance, pressure resistance, and durability, it can handle harsh environments. Triple seal structure to prevent liquid leakage The primary seal compresses the body seal onto the valve body. The secondary seal is provided by an O-ring. The tertiary seal is achieved through a tapered push on the valve rod. This triple seal structure completely shuts out leakage to the outside of the piping.
