Rising axis sliding gate valve

The rising axis sliding gate valve is a shut-off valve with a metal seat of the type of axis with an external thread, which is suitable for both fully open and closed positions, and can be opened and closed manually through a special key or wrench if installed in a chamber, or by an axis if installed underground, or automatically by installing a special actuator. Uses of the rising axis sliding gate valve In cold and hot water installations, urban and rural water supply and sewage, agricultural irrigation projects, water transmission lines in various industries, oil, oil and gas transmission lines, bitumen and non-corrosive fluids, and other similar industrial uses, installations, power plants, etc., up to 180 degrees Celsius with a body and cap made of GGG40 ductile iron with special packing for operation up to 250 degrees Celsius. Technical features and advantages of Arashir Khorasan rising axis sliding gate valve This type of gate valve is based on Japanese NBC technology and is made for the first time in Iran and has the following special advantages: Due to the location of the tongue transfer nut outside the gate valve, this valve does not wear out due to sedimentation and corrosion of the nut. Its axis type is rising, which determines the open or closed state of the gate valve, which is important in controlling the production process. – Protection against corrosion due to the electrostatic powder coating of the internal and external blinds – Long service life due to the use of stainless steel on the shaft and sealing surfaces as well as the tongue made of ductile iron GGG40 – Ability to install an electric actuator Rising axis slide gate valve Rising axis slide gate valve Specifications of the rising axis slide gate valve – Made according to DIN 33523 standard and national standard 3363 – Body and cap made of gray cast iron 25 according to DIN EN 1561 standard and national standard (406) or ductile iron 40 GGG (according to DIN EN 1563 standard and national standard (1795) – Tongue made of ductile iron GGG40, stainless steel bearing Tongue for use for fluids with high viscosity such as (bitumen) as well as high working pressure and temperature integrally made of ductile iron GGG40 and upon request for use in special cases made of Stainless steel is also made. – The material of the shaft is stainless steel 1.4021 (X20r13) with excellent wear resistance and has exceptional strength and is machined by CNC machines with extremely high precision and the shaft nut is made of brass machined by CNC lathe The material of the body ring and also the tongue ring for the type with a ring tongue is stainless steel 1/4104 (X14CrMoS17) – The distance between the flange and the valve flange is according to the standard DIN EN 3202 -11-558 – F4&F5 (DIN EN On request, it is also produced with the dimensions of the Russian GIS standard. – The dimensions of the flange are according to the standard DIN EN 1092-2) 2501) – The color coating of all cast iron parts is by blue epoxy powder paint baked by electrostatic method with a thickness of 150 microns or on request 250 (microns) : Packing The packing used is made of Teflon or Asbestos-free graphite is resistant to high temperatures.
