Gate valve

  • Knife gate valve
    TANA knife gate valves are available in various designs, one-piece body and two-piece bodies, rising stem and non-rising stem, uni-direction and bi-direction structures, resilient and metal seat rings, bonnetless and bolted bonnet designs. For optional designs, deflection cone could divert the flow of abrasive slurries and protect valve seat from abrasion, V port disc and through conduit design are used for throttling service, per customers' requirements.
  • Pressure seal gate valve
    The design and manufacture of high-pressure valve is in accordance with API600, the High Pressure Seal Gate Valves has a beautiful shape, compact structure, reliable sealing. Valve for the Class 900lb-Class2500lb various tubes on the road. High-pressure self-sealing valve has the following advantages:
    1) Self-sealing high-pressure valve allows the structure of the valve body, valve cover tight junction structure, the provincial Public Works save cost, safe and reliable. 2) valve pressure in the valve cover seal, the use of the modular structure to achieve linear sealed its seals at the same time the use of austenitic stainless steel, anti-cavitation, extended life, thereby ensuring that the valve seal under high-pressure differential did not leak.
  • Metal seat wedge bypass gate valve
    TANA Bypass gate valves have the back seating design.For stainless steel gate valve, the back seat is machined directly in the bonnet or is machined after welding .When the gate valve is at fully open position, the sealing of the back seat can be very reliable .However, as per the requirement of API600, it is not advisable to add or change packing by the mean of back seating when the valve is pressure containing.
  • Cast steel gate valve
    TANA cast steel gate valves are designed and manufactured to provide maximum service life and dependability. All gate valves are full ported and meet the design requirements of American Petroleum Institute standard API600&API 6D,British standard BS1414 & BS EN 1984 and generally, conform to American Society of Mechanical Engineers standard ASME B16.34. Valves are available in a complete range of body/ bonnet materials and trims.Material:WCB,LCB,WC6,WC9,CF8,CF8M,CF3,CF3M,CF8C,also special material like S31803,S32750,CN7M.
  • DIN standard Gate Valve
    DIN standard gate valve has bellow features: Outside Screw and Yoke,Bolted Bonnet ,Flexible Wedge, Full Guided,Rising Stem and Non-Rising Handwheel, Welded Seat Ring,The material has GS-C25,CF8,CF8M. Application:Industry, powerstations, flue gas purification plant, processing technology, gas supply, vapour facilities, recycling facilities, vacuum facilities, hot water, thermal oil applications, general plant manufacturing, etc. Medium:Steam, gases, hot water, thermal oil, ammonia etc.
  • Slab gate valve
    Slab Gate Valves(Parallel type gate valves, Through Conduit Gate Valves)are widely used in oil, natural gas long-distance pipelines and gas fields as open/close control valves. Valves used in forging or casting body, the gate designed with diversion holes, non-diversion holes; single plate and double plate structure; Seat used bi-direction seal seat which mainly based on the metal seat sealing and assisted with soft seat sealing as a second type of seal. The series of parallel type gate valve has rational design, compact structure, sulfur resistance, corrosion resistance, wear-resistant, reliable sealing, and light torque of switches, easy-to-use.
  • Cast iron gate valve
    Cast iron gate valve provides full flow with minimal pressure drop. The cast iron gate valve has flat face end connection for easy installation and accessibility. Outside screw and yoke (OS&Y) and Non-rising stem gate valves structure,Outside screw and yoke (OS&Y) gate valves are recommended when positive shutoff and a quick visual indicator of open/closed position is required. Non-rising resilient seated gate valves solve the problem in general gate valves such as leakage, rusting etc.and saves installation space.Bolted bonnet, Solid wedge, Iron body bronze mounted (IBBM), flanged flat face end connections. Conforms to MSS SP-70 DIN3352,BS5163,KS B 2350.
  • Forged steel gate valves
    TANA forged steel gate valves have set their own standards in many industries, much like our super-specialty valves.
    Available in sizes, from 1/4” to 2” for pressure 800lb ~2500lb with forged carbon steel (ASTM A105N); forged alloy steel (ASTM A 182 Gr. FS/F11/F22); forged stainless steel (ASTM A 182 Gr. F304/F304L); forged stainless steel (ASTM A 182 Gr. F316/F316L). 
    Rotary table surface grinding and imported lapping machines ensure a fine surface finish of 100% leak-tightness. The trim materials is hardened and tempered for higher durability and performance. Further stellited trim can also be provided. The valves offered can meet both API and BS Standards requirements.
