Medium and low pressure quick coupling, dual port open type, TL type.

Medium and low pressure quick coupling, dual open type, TL type.

This is a two-way open (through) type quick coupling that does not have a valve mechanism in either the socket or the plug. 【Features】 ■ Since it is a through type, it has the largest flow rate and almost no flow resistance. ■ Due to the low pressure loss, it is suitable for piping connections of high-viscosity fluids, steam, and powders. ■ Depending on the connection target, there are options for male thread (M) connection, female thread (F) connection, and hose (H) connection, allowing for free combinations. ■ Both the socket and the plug have a structure without a valve, so the fluid flows out to the outside. ■ Once set, the fluid is completely sealed by an O-ring. ■ There is no pressure loss, and the fluid flows smoothly through the coupling. 【For details on the TL type coupling, please refer to the download.】

High-pressure, stainless steel double-acting quick coupling, SH type.

High-pressure stainless steel double-acting quick coupling, SH type.

This is a quick coupling with automatic valves on both the socket and plug, designed for dual-path opening and closing. 【Features】 ■ As a dual-path opening and closing type, it ensures that both the socket and plug achieve a complete seal the moment they are separated. ■ The main body is made of corrosion-resistant stainless steel SUS304, making it ideal for use in harsh environments such as steelmaking and onboard ships. ■ Equipped with a standard locking mechanism to prevent accidental disconnection due to vibrations or impacts. ■ The valves of the socket and plug instantly adhere to the valve seat surface, closing the passage. ■ The valves of the socket and plug push against each other to open the passage, allowing fluid to flow. ■ To prevent leakage, a backup ring is used, and it is completely sealed with an O-ring. * Please use a dust cap when separating and leaving it unattended. 【For more details on the SH type coupling, please refer to the download.】

Medium and low pressure, dual path open-close quick coupling S.P. type

Medium and low pressure, dual-path open/close quick coupling S.P. type

This is a dual-path open/close quick coupling equipped with automatic valves on both the socket and plug. 【Features】 ■ Since it is a dual-path open/close type, both the socket and plug achieve a complete seal the moment they are separated. ■ The passage opens simultaneously with the connection, and closes simultaneously with the separation, resulting in minimal fluid loss and air contamination. ■ There is a wide variety of materials available for the main body, and valves, packing, and O-rings should be used according to the type of fluid. ■ The valves of the socket and plug adhere instantly to the valve seat, stopping the flow of fluid. Therefore, there is no fluid leakage. ■ The valves of the socket and plug push against each other to open the passage, allowing fluid to flow. ■ The O-ring inside the socket provides a complete seal, preventing any external leakage.
