    JTR-DT22

    Disc Type (32A-50A)

    Existing air conditioning methods had loss of steam and early deterioration of the disks and sheets as major shortcomings caused by frequent operation. But this product ensures optimum operation thanks to the thermal insulation. The disk and sheet have undergone thermal processing to the stainless steel beams made of Martensite for greater durability and smooth operation. All the sealing parts have Teflon gaskets applied to prevent leakage. Even with disassembly and re-assembly for repair and maintenance, there is no disfiguration and thus the product can be used for an extended period of time. The built-in strainer prevents breakdowns caused by impurities. The maximum back pressure is 80% of the primary pressure. When selecting the size of the trap, select 2-3 times that of the required capacity. (This is dependent on the type of equipment and operational conditions.)

    JSV-PF100

    Pilot Operated Type

    It is used in various pressurized containers and gauging devices of oil & gas plants and petrochemical plants, and in particular as a substitute where spring load types cannot be installed.

    This product has acquired a capacity and quality certification from ASME ("UV" Stamp). It can be used in places where the bellows type cannot be used due to the excessive pressure, or where a large capacity valve is needed but there is not enough space. If can be used where the process requires a detection of pressure in one place while another place requires the outlet of liquids. It is also appropriate for cases where remote control is needed. For leakage, the API STD 527 standard applies."> It is used in various pressurized containers and gauging devices of oil & gas plants and petrochemical plants, and in particular as a substitute where spring load types cannot be installed.

    JTR-DT41

    Disc Type (15A-25A)

    The main body and sheet are of one piece, making it highly durable in high temperature and high pressure, and thus appropriate for steam engines or nuclear power generators. The structure is simple and repair is easy. The disk has undergone thermal treatment for increased hardness and greater durability. The thermal insulating cap was designed to prevent any impact from the exterior air. The built-in strainer prevents breakdowns or errors caused by impurities. When selecting the size of the trap, select one that is 3 times that of the necessary capacity for the trap. (This is dependent on the type of equipment and operational conditions.)
