• valve

Equipped with a key lock function using a padlock (sold separately). This model is oil-free and complies with the RoHS directive (10 substances). It allows for secure locking in both fully open and fully closed states, preventing accidents caused by unintended contact with the handle or vibrations, and is effective in preventing equipment and piping failures as well as enhancing safety measures. Parts are degreased and cleaned using a hydrocarbon-based cleaning machine, and after drying, they are assembled without using any oils such as grease by hand, and shipped in individual packaging. Additionally, due to the full bore equivalent specification where the inner diameter of the connecting piping is almost the same as the valve bore diameter, fluid resistance is low when fully open, and pressure loss is minimized. Moreover, there are numerous achievements in custom-made (specification changes) products based on this model.

• Piping Materials

At Hamai, we are capable of manufacturing custom-made valves that cater to various industrial machinery, equipment, and piping, centered around ball valves. We can accommodate not only simple parts replacements but also modifications to the main body shape and combinations of different standards, as well as fully customized designs to meet unique specifications. Special specifications such as heat resistance, pressure resistance, corrosion resistance, chemical resistance, oil-free design, and low environmental impact are also available. ■ Examples of Requests - Change in handle shape (lever handle/knob handle). - Change in handle opening direction (clockwise/counterclockwise). - Change in O-ring material (NBR/FPM, etc.). - Incorporation of different standard screws (Rc screws/G screws/NPT screws, etc.). - Modification of shape to fit in narrow spaces. - Compatibility with special fluids. - Integration of multiple ball valves used together. - Special oil-free design. - Addition of a locking function to prevent accidental operation, etc.

• valve

A small pneumatic automatic valve made of stainless steel, equivalent to a large flow full bore. Due to its flange connection, it is possible to clean internal components such as balls by disassembling it. Additionally, the aluminum actuator equipped with a rack and pinion mechanism is high-torque, lightweight, and compact, capable of rotating in 90° increments. It is ideal for piping in narrow spaces and for installation in devices that require miniaturization. Furthermore, there are numerous achievements in custom-made (specification changes) products based on this model.

• Piping Materials
• valve

The piping component "ball valve" includes a lineup of "brass ball valves" such as the BBS series, which emphasizes versatility and cost-effectiveness, and "stainless steel ball valves" like the BSS series, tailored to the needs of the chemical and food industries. It also features "LP gas ball valves," which are ideal for LP gas and gas taps, and "pneumatic automatic ball valves" such as the LAS series, designed to enhance labor efficiency. 【Product Lineup】 ■ Brass Ball Valves ■ Stainless Steel Ball Valves ■ LP Gas Ball Valves ■ Custom Ball Valves ■ Pneumatic Automatic Ball Valves ■ Motorized Automatic Ball Valves, etc. *For more details, please request materials or view the PDF data available for download.
