[INQ. NO. 1809M01] By coating the disc with EPDM rubber ‘elastic body’ the restitutive power of this grooved end butterfly valve (BO-G310) between the valve’s body and rubber helps to maintain air tightness. A disc rotates 90 degrees to control the fluid in motion, maintaining high responsiveness under operations with low friction loss and low torque.
Fast operation is possible thanks to simplified opening/closing processes. This valve is applicable to control of low/high-pressure water. It is mostly used for firefighting pipelines and industrial water lines.
It is designed for use in fire protection systems where a visual indication is required as to whether the valve is open or closed. It has grooved inlet and outlet connections that are suitable for use with grooved end pipe couplings that are listed and approved for fire protection systems.
The supervisory switches transfer their electrical contacts when there is movement from the normally open or normally closed disc position during the first two turns of the hand wheel.

Regulator housing (insert molding) can make molded products by integrating plastics and other components (metal, cables, and PCBs, etc.) within a mold to make high value-added products that has properties of metal and plastic.
even when fully charged is applied. Design was intended for easy replacement of parts in case of problems. Advanced technologies of cylinder design and manufacturing are applied, the company can thus respond promptly to requirements of customers, regardless of pressures, sizes, volumes or vehicle models for LNG fuel cylinders. HanbeeCryo has developed cylinders for storing and transportation of liquefied gases (LO2, LN2, LAr, LCO2, LNG, etc.). Those are being produced through a strict inspection process prescribed by high pressure gas related regulations and laws. HanbeeCryo has been supplying the LGC with economical prices by diversifying the specifications of the desired products according to the needs of the consumers by capacity and pressure by the R&D and management of the advanced technique since its establishment.
When you need superior actuator innovation, look for the “Manufactured with high technology” seal of approval. Accept no substitutes!
U-Care Mat, having obtained KC Certification for the first time in the industry, is strong and durable (the triple structure of upper, middle and bottom plate), and the mat height for it is low and the edge slope is gentle. This product is manufactured with user safety as a top priority.
suction force even to the corner of the maximum size.
The cleaning equipment of refrigerant pipes developed by Bumsuk Engineering is a single piece of equipment combined with the functions of recovery and regeneration capable of recovering and regenerating the existing refrigerant and uses the recovered refrigerant as a cleaning agent.
real-time in the low-speed driving of 30km or slower per hour in addition to the high-speed driving and notifies the driver of the situation to prevent collision. Thus, INAVI X3 Cube supports the largest level of functions such as existing lane departure detection systems, front-car departure alerts, traffic light change alerts, rapid-curb deceleration alarm systems. etc.
