It is operated by the pilot and does not require auxiliary power such as from compressed air or electricity. Compared to the direct impingement type, it has a larger capacity. The range of pressure adjustment is wide and adjustments can be made easily. With the built-in "pressure relief valve filter" with a practical design patent No.13137, errors caused by the scale or impurities inside the pipes are prevented. Compatible with disks/ sheets. Leakage: Less than 0.05% of the standard flow

This is an air vent for steam. As a valve that removes the air that remains within the steam system or the non-condensable gas, it prevents the heat conduction from becoming uneven due to disruption in the air flow, as well as slowing down the corrosion of the pipes. The valve closes with a temperature change in the steam. Once air or non-condensable gas flows in, the temperature falls, triggering the valve to open to let the air or non-condensable gas out. The degree to which the metal bends and the force applied varies according to the pressure in the steam line used. This helps with the sealing effect and an extended useful life of the product.

This device allows the status of fluid flow to be verified with the naked eye from both sides to accurately see whether the steam trap works properly. Special reinforced glass is applied for greater resistance to pressure. For the flapper type and ball type products, you can verify the status of even the subtlest flow.

Jokwang I.L.I has designed this technology, combined it with our more than 50 years of valve experience and developed a product to accurately determine the operational condition of any type, make and model of various valves without a labor requirement.

This item is used to remove the scale and impurities from various pipelines. It is also attached to the front of various relief valves, control valves and steam trap devices to prevent errors or breakdowns in machinery caused by impurities. The screen has been designed with sufficient filtering surface, taking into account the undermined flow caused by the blockages triggered from impurities.

It is a large capacity pilot type temperature control valve that has a larger capacity compared to the direct impingement type and can be used in places where there is a big difference in pressure before and after the valve. It is fit for temperature control of large storage tanks, and is also used in hot water tanks or thermal exchangers. The range of temperature adjustment is categorized by 20℃ and there is very little variance in temperature. Installation is also very simple as it does not require an auxiliary power source such as electricity. The connecting pipe is covered with a flexible tube to protect from damage.

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.)

This is a direct impingement type pressure relief valve. The small size makes it easy to handle, and the simple structure increases durability. It is particularly excellent when used for the water supply pressure control on each floor, from the water tank in high-rise buildings. Adjustment pressure is easy and safe. Interior inspection can be done with a simple disassembly of the upper part, making it easy to maintain.
