Features of Aska Special Valves

All Aska valves are designed by engineering staff with considerable experience. Aska has integrated the latest manufacturing system to achieve the world's highest quality level. Designed by CAD system, manufactured by CNC machining centers and controlled with Manufacture Planning system.
We have taken these steps to provide our customers the very best.

  1. THE ORIGINAL VALVE
    All of Aska valves are manufactured with customer's order. Valve design reflects customers specifications,so the valves are all unique. Selections for example,heating jacket,connections,operators,flushing valves etc.

    Valve seat and valve disc are all stellite welded face. High precision machining assures a tight seal even under vacuum.
  6. HEAT TREATMENT
    Welded valves are aged by heat treatment to avoid physical stress deformation.
  7. INSPECTION AND TEST
    In addition to maker's standard inspection, operation and leakage test at customer specified high temperature is available.
  8. DESIGN CODE
    JIS, JPI, ANSI and DIN standard can be applied. Other standard can be applied on request.
  9. MATERIALS
    Stainless steel is standard : CF8(SS304), CF8M(SS316) etc. Special materials like Hastelloy(R), Titanium, Carpenter(R), Monel(R), Nickel etc are applicable on request. Teflon(R) Coating, Lining available.
