The 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.
