Products JOKWANG I.L.I manufactures some of the world's highest quality products based on advanced technologies.
Safety Valve The safety relief valve automatically releases fluid from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. ¡ØASME Certified.
Safety Valve Our products acquired certification for capacity and quality from the ASME ("UV" & "V" stamp), the Occupational Safety & Health Agency and The Korea Gas Safety Corporation.
Pressure-Reducing Valve The pressure reduces valve reduces the input pressure of a fluid to a desired value at its output, by controlling opening according to fluid energy.
Pressure-Reducing Valve Our product is operated by the pilot and does not require auxiliary power such as from compressed air or electricity, which is easy to install and to manage.
Steam Trap A steam trap is a automatic valve used to discharge steam condensates effectively and to prevent leakage of steam.
Strainer The strainer uses to remove scale and impurities from various pipelines. Also it protects piping system by preventing errors or breakdowns in machinery caused by impurities.
Glove Valve The glove valve consists of an angled disk and a valve sheet. It throttles the flow by moving a plug connected with disk vertically.
Thermostatic Valve The temperature control valve uses to control temperature of hot water tanks, heat exchangers, oil preheaters, drying devices. It is operated by the pilot and does not require auxiliary power.
Air Vent The air vent removes air or non-condensable gases that remains within pipe or steam systems.
Air Trap The air Trap removes steam condensates in the air or gas piping systems. It prevents corrosion on the machinery and line and disruption in the transport of air or gas.
Site Glass The sightglass 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.
Site Check The sightcheck allows the status of liquid flow and any leakages to be verified with the naked eye. You can check whether the steam trap is working properly and take necessary measures by looking at the overall status of the system.
Changeover Valve The COV uses the valve block (device) to control the flow of fluid to either of the two safety valves by moving the valve block (SPINDLE) horizontally connected to the disk (DISC) in one of the two SEATs depending on the situation.
Changeover Valve It enables continuous operation of the pressure system, and two safety valves are connected to the pressure system via the COV. This arrangement enables uninterrupted operation of the system as one safety valve is running and the other acts as the standby safety valve.
