When using metal valves in seawater, issues related to corrosion and durability inevitably arise, leading to a frequent use of resin valves, which are vulnerable to vibrations. In response, our company has developed metal valves for seawater that can be used for extended periods: "solenoid valves, flow control valves, and air release valves," achieving significant total cost reductions compared to resin. 【Countermeasure Introduction】 ■ Solenoid Valve: Diaphragm structure that blocks fluid entry to the movable iron core. ■ Flow Control Valve: Corrosion measures including a special coating on the spring. ■ Air Release Valve: Incorporates a ball in the valve body and our unique crystallization countermeasures. In addition to these three products, we also offer a variety of valves compatible with seawater and special fluids, including check valves! We are actively engaged in new product development and have established a system to assist you when you encounter difficulties. For more details, please refer to our catalog or feel free to contact us.

The Keihin "LP2 Series" is an inline, compact piston-structured air-operated valve. The ball section is inline, requiring minimal space for installation when screwing in, allowing for space-saving in machinery. It can also be mounted on the wall, contributing to flexible design. Additionally, its durability is extremely high; while a typical ball valve may leak after 10,000 to 30,000 cycles, this product lasts for 100,000 cycles, reducing the hassle of replacement. 【Features】 ■ Space-saving installation due to inline design ■ Easy piping, reducing contact with other equipment ■ Installation can be done vertically, horizontally, or diagonally ■ Piston structure significantly improves durability compared to ball structures ■ Made of stainless steel, compatible with a wide range of fluids ■ Standard equipped with a operation confirmation indicator. *For more details, please refer to the catalog or feel free to contact us.

This is a general-purpose pneumatic operated piston valve that can be used with water, oil, and steam. It automatically closes due to the force of a spring, making it suitable for emergency shut-off (shut-off valve). It is ideal for various light installations and machinery.

Are you having trouble finding a flange-connected valve, saying "there are only threaded products," or "I found a nipple flange on the internet, but the face-to-face distance is too long, and I can't secure enough piping space..."? Our company sells welded fittings that connect nipples and flanges with R × JIS 10K-FF connections as shown below. Please feel free to contact Keihin when you have any issues. ◆ Features - The face-to-face distance is short, at 39.5mm on one side (79mm for a set). *This dimension is for 25A. - We offer diameter sizes from JIS 10K-FF 15A to 25A. - We have two material options available: SS400 and SUS304.

At Keihin, we handle a variety of special valves that are not available from other manufacturers. Customization is possible to meet various conditions, such as accommodating high pressure, low temperature/high temperature, and changing materials according to the corrosiveness of the fluid. We can control fluids such as water, air, oil, and steam. Specifications that are difficult for other manufacturers can be consistently managed from design to production, responding to requests regarding fluid specifications such as fluid, pressure, and temperature, as well as material, connection, and size. 【Example of Products】*Customization is also available for catalog-listed items ■ Pneumatic Piston Valve 　⇒ Products compatible with 60 to 80 MPa ■ Solenoid Valve 　⇒ Products compatible with 20 MPa 　⇒ Products compatible with 250°C 　⇒ Products compatible with -196°C ■ Electric Valve 　⇒ Electric valve with a resin body material and spring return type (emergency shut-off valve) ■ Check Valve 　⇒ Products made of Hastelloy material ■ Others 　⇒ Various valves compatible with seawater 　⇒ OEM products for specific customers, etc.
