    JSV-BF21/22/31

    Balanced Bellows Type

    This product has been designed according to the KS B 6216 specifications for safety valves used for steam and gas. A balance structured bellows is inserted to ensure there is no effect from the pressure, and the structure ensures the liquid let out does not leak out of the main body. The material of the bellows is SUS316, making it strongly resistant to corrosion. The spring has been manufactured within the range of the maximum effective stress of the material. It has received certification from the Occupational Safety and Health Agency and Korea Gas Safety Corporation. For leakages, the standard of API STD 527 applies.

    JTR-FT12

    Ball Float Type (15A-50A)

    The ball trap for steam is a mechanical type using buoyancy. It is used in various steam facilities, including thermal exchangers, unit heaters, driers or at chemical plants. With its high precision technology, it offers great energy efficiency. The key part is made of stainless steel beams that have been processed for greater durability. The built-in air vent capsule prevents disorders caused by air. As it is a continuous outlet type, it can be used for numerous purposes and can let out a large quantity of steam condensate. There are three types of sheets designed to fit the various differential pressures, so select the one that best fits your differential pressure. When selecting the size of the trap, select one that is 2-3 times that of the necessary capacity for the trap. (This is dependent on the type of equipment and operational conditions.)

    JTR-BT21

    Bucket Type (15A-25A)

    The bucket faces downwards and the separation of gas and water helps prevent disorders caused by air while conserving energy by preventing the leakage of steam. Key parts are made of stainless steel and the disk has undergone thermal treatment for greater durability. There are four types of sheets designed to fit the various differential pressures, so select the one that best fits your differential pressure. When selecting the size of the trap, select one that is 2-3 times that of the necessary capacity for the trap. (This is dependent on the type of equipment and operational conditions.)
