Especially, vacuum valve is applicable in providing isolation for the turbine condensation system and negative pressure system of power plant, chemical factory, and paper mill, etc.
    1. Flanged Gate Valve Flanged gate valve is used with water, steam, oil, and other medium. It is manufactured basing on the connection standards of JB/T 79-94. The valve is manually operated, featuring stable performance and high safety. The nominal pressure of our flanged valve ranges from 1.6MPa to 2.5MPa.
    1. Bellows Seal Globe Valve Bellows seal globe valve is suitable for isolation and flow control duty in industrial, chemical, medical, and power applications. The nominal pressure ranges within PN1.6~4.0MPa, and the allowable working temperature is -29~350℃.
    1. Soft Seal Globe Valve Soft seal globe valve is used as a regulator for medium including water, steam, oil, and non-corrosive gas. It is applied in environment between 400℃ and 550℃, with the nominal pressure to be smaller than 4.0MPa.
    1. Power Station Globe Valve Power station globe valve is applied in regulating flow in a pipeline, with the medium to be water, oil, high-temperature steam, and other non-corrosive gas. It is widely seen in power plant, chemical plant, oil plant, etc.
    1. Flanged Globe Valve Flanged globe valve is mainly designed for regulating water, steam, and oil for industrial applications. It is manually or electrically operated.
    1. Y-Pattern Globe Valve Y-pattern globe valve is designed for shutting off or regulating pipelines in chemical factory, power plant, and fertilizer plant, etc. It is suited for nominal pressure of 1.6~4.0MPa and working temperature of -29~350℃.
    1. Disc Type Check Valve The ZHYH46 and ZHYH46EJ series disc type check valve manufactured by KIST is applicable in the water supply pipelines of water, sewage, and seawater to prevent backflow and water hammer effect.
    1. Exhaust Check Valve Exhaust check valve allows air or other gas to flow only in one direction, and helps to eliminate backflow. It is applied in the water supply preheating system of power station or other industrial pipeline systems.
    1. Ball Check Valve Ball check valve is applied in gas supply, plumbing, water distribution, sewage treatment, power stations, and especially in submersible sewage pump. The allowable working temperature of the valve is 0~80℃.
    1. Rubber Flapper Check Valve Rubber flapper check valve is designed to offer a strong and quick seal for water supply and drainage system to prevent backflow and water hammer effects. For water tank or swimming pool, the swing check valve can be mounted at the bypass pipes to prevent the water from flowing back to the supply system.
    1. Micro Ball Check Valve Micro ball check valve is mainly applicable in plumbing, water supply, sewage treatment, gas supply, and power station to prevent backflow effects. It adopts a rubber-covered ball as the disc, which will rolls up and down inner the valve driven by the medium.
    1. V-Port Ball Valve V-port ball valve generally has a V shaped ball or seat, which allows the orifice to be opened and closed in a more controlled manner, and thereby adjusting the flow velocity as required. It commits no block or separation between the seat and the ball.
    1. Floating Ball Valve Floating ball valve is used in pipelines to cut and distribute flows. The most distinguished feature of the valve is that it has no support for the ball, which appears a floating state between the 2 seats.
    1. Pigging Valve The pigging valve produced in KIST shows powerful capacity in cleaning pipe, isolating and transferring medium, and detecting pipeline system. It works to receive and launch pigs in water, oil, and natural gas pipelines.
