    High-pressure difference trap valve
    Overview:
    ◆ This series of valve is used for regular and continuous sewage system of boiler in thermal power plant; water delivery system and drainage system of power station.
    ◆ The main seal is made of the same material to ensure the same thermal expansion coefficient to ensure sealing and anti-seize. The main seal is hardened, high hardness, wear-resistant, erosion-resistant, and long life.
    ◆ The back pressure of the throttling device can be adjusted by adjusting the number of throttling cylinders and the diameter of the orifice in the throttling cylinder.
    ◆ The high temperature resistant spring provides continuous sealing thrust between the valve disc and the valve seat, and is assisted to maintain the seal by the pressure of the pipeline.
    ◆ Pneumatic + manual driving device is safe and reliable. Once the automatic control fails, the valve can be operated by manual driving.
