Stainless steel ball valve with key lock function and lockout.

Stainless steel ball valve with key lock function and lockout.

Ideal for lockout of semiconductor manufacturing equipment and facility piping!

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 reliable 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 grease or oil 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.

Butterfly valve

Butterfly valve

A butterfly valve with a simple structure, perfect for long-term use.

The valve rod adopts an eccentric structure that does not pass through the rubber valve seat, resulting in less localized friction and fatigue on the rubber valve seat. Additionally, the valve box seat area is coated with hard chrome, ensuring stable sealing performance. The structure is also designed to be simple, making it ideal for long-term use. 【Features】 - The eccentric structure that does not allow the valve rod to pass through the rubber valve seat minimizes localized friction and fatigue on the rubber valve seat, and the simple design ensures safe long-term use. - The valve box seat area is coated with hard chrome, and the structure includes an O-ring type rubber valve seat on the valve body side, allowing the rubber valve seat to be pressed against the valve box seat area by fluid pressure, which reduces wear and fatigue on the rubber valve seat and provides balanced sealing. Furthermore, this structure improves sealing performance as the pressure increases. - The O-ring type rubber valve seat results in less resistance around the entire seat area, reducing the operating torque during closure, allowing for smooth opening and closing. - It is compatible with both vertical and horizontal configurations. For more details, please contact us or download the catalog.

Flow control butterfly valve

Flow control butterfly valve

A butterfly valve with flow control that has performance equivalent to JWWA B 138 standard butterfly valves.

It has performance equivalent to the JWWA B 138 standard butterfly valve, and by attaching a flow control plate with comb-like notches and numerous holes on the downstream side of the valve body, it disperses the water flow into fine jet streams, suppressing the occurrence and growth of cavitation. With low vibration and low noise, it enables "throttling operation," which was considered difficult with conventional butterfly valves, allowing for extensive flow control. 【Features】 - The flow control plate with comb-like notches and numerous holes disperses the water flow into fine jet streams, compensating for the negative pressure on the downstream side of the valve body and suppressing the occurrence and growth of cavitation. - Since the flow control plate can suppress the occurrence and growth of cavitation, the cavitation characteristics are improved, making throttling operation possible, which was considered difficult with conventional butterfly valves. Additionally, the generated cavitation is finely dispersed, reducing the vibration and noise that occur during throttling operation and expanding the range of use. - The wetted surfaces on the inner side are coated with a powder coating known for its resistance to cavitation, enhancing durability and also effectively addressing red water issues. - It is compatible with both vertical and horizontal orientations. For more details, please contact us or download the catalog.

Dynamic Air D70P Type Air Valve with Water Hammer Prevention Design

Dynamic Air D70P Type Air Valve with Water Hammer Prevention Design

A nylon resin air valve that prevents sudden blockage and suppresses water hammer.

During water flow, a large amount of exhaust is performed, and after the water reaches the valve, the diaphragm-structured valve body closes gently, preventing sudden shut-off and suppressing water hammer. Features: - The diaphragm-structured valve operates gently and quietly, accommodating large exhaust and intake while preventing rapid pressure increases due to sudden shut-off. - The upper air valve performs pressure release exhaust. - Even when there is no water in the pipeline, the valve remains closed, preventing the intrusion of insects and foreign objects into the pipeline. - The rolling seal structure ensures long-term stable operation and water tightness. - By using a drain valve specification (with a ball valve), drainage can be performed from a 50mm drain outlet using only the operation of the ball valve. For more details, please contact us or download the catalog.
