The ATKZ series knife gate valve is dedicated to solving specific problems in recirculation and excretion. Its configuration can minimize the impact of the following problems.The seat is covered with a thick layer of special impact alloy layer on the inner diameter and surface to protect it.The gate is made of extremely hard corrosion-resistant alloy.Together they formed an effective, durable scissors, cutting wire, nails and other debris.
● The physical damage (brake and seat) of the sealing surface: the sealing effect of steel wire, nails and other debris has been reduced to an unacceptable extent.
● Blockage: steel wire, nails or other debris pile up at the bottom of the valve, causing the valve to be unable to completely shut off and leak.
● Poor sealing performance: caused by surface damage, friction and high cycle condition.
● Excellent performance and convenient installation
● Specially designed heavy open-cast stainless steel body can prevent the formation of small holes and prevent nails and wire from assembling here.
● Besides being an effective shear, the hard gate can resist surface damage and maintain sealing performance.
● Special wear - resistant seal and live - load sealing ring achieve high - cycle sealing performance.
● The valve is simple, efficient and economical.
