Control valve (constant flow valve for seawater)

Control valve (constant flow valve for seawater)

Seawater-compatible constant flow valve

Our company offers a rare seawater-compatible constant flow valve in Japan. It can be used for various applications such as seawater desalination and ballast water control. Regardless of pressure fluctuations, it can maintain a constant flow rate on the secondary side, and since it is self-sufficient, there is no need to set up a power supply or system. The maintenance cycle is also long, so if you are considering long-term cost reduction, please feel free to consult us. In addition, our company not only handles catalog products but also offers customization, new product development, and OEM products according to customer requests. *Please feel free to consult us if you have any issues related to valves.

Constant Flow Valve "FVG Series"

Constant Flow Valve "FVG Series"

No need for power supply, air pressure, or regulators! Maintains a constant flow rate even when fluid pressure fluctuates.

The "FVG Series" is a self-operated constant flow valve that operates based on the pressure difference between primary and secondary pressures. No external inputs such as power supply or air pressure are required at all. It easily controls a constant flow even with pressure changes. Additionally, we offer other products such as the variable flow type constant flow valve "NFVT Series" for small flow rates and the all-metal flow meter equipped constant flow valve "MP-NFVT Series." 【Features】 ■ No need for power supply, air pressure, or pressure gauges ■ Free to change the set flow rate ■ Can be manufactured for gases ■ Accurate precision (within ±2% F.S.) ■ Quick response speed *For more details, please refer to the PDF document or feel free to contact us.
