Specifications

Dynaclean

Dynaclean has a function to protect the hydraulic fluid in the oil tank from contamination and oxidation.

When the fluid surface lowers in the closed fluid tank, the bladder in the Dynaclean shrinks and sends the air in it to the closed fluid tank.Then the air pressure in the fluid tank can be stabilized.

When the fluid surface rises in the closed fluid tank, the bladder in the Dynaclean inflates and absorbs the air in it from the closed fluid tank.
Then the air pressure in the fluid tank can be stabilized.

This product not only complies with the “High Pressure Gas Safety Law,” but also, you can use this spring-type safety valve for nitrogen gas and compressed air with accumulators beyond our brand. Moreover, this versatility enhances its utility in various applications.

This device is not only capable of swiftly responding to changes in the liquid level within a sealed tank but also plays a crucial role in maintaining constant internal pressure. Additionally, the act of sealing the tank serves an important function; it markedly reduces the risk of contamination and oxidative deterioration of the working fluid. Consequently, this approach enhances the longevity and reliability of the system’s operation, ensuring its effectiveness over time.

By incorporating a “pressure intensifier” into the hydraulic unit and subsequently connecting a nitrogen cylinder to the gas side of the pressure intensifier. One can efficiently generate high-pressure gas.

This sequence of actions facilitates the process of elevating gas pressure to the desired levels. Thus enabling the system to achieve its intended high-pressure functionality.

This product uses a piston to separate liquid and gas.
Can handle high flow rates.

The G series is an inline-type accumulator.
The pressure receiving area is large compared to the gas volume, so it can be installed in the middle of piping and is ideal for absorbing pulsation.

In addition, this is an easy-to-maintain upper part accumulator that allows bladder replacement and disassembly inspection while piping is in place.

The S series (Solefty) is an inline-type accumulator.
It has a mechanism with a large flow rate and low-pressure loss and can be used vertically or horizontally.

Remove the poppet from the oil supply and drain valve and provide a small passage hole instead to protect the bottom of the bladder.

Suitable for pulsation absorption and shock buffering in low-pressure lines.

Ideal for pulsation absorption and shock buffering.

This is a product with a mechanism that allows the entire amount of fluid to go in and out of the accumulator, increasing the effects of pulsation absorption and shock buffering.
