Stainless Steel Needle Valve By Structure

  • Straight bar stock needle valve

    Stainless steel straight needle valve construction uses a straight flow path through the valve body.

    The bar stock needle valve is suitable for a wide range of applications. It allows precise regulation of flow.

  • Straight forging needle valve
    Stainless Steel Straight Forging Needle Valve

    Forging integral needle valves have a good reputation for strength and durability. They are an ideal choice for high-pressure and high-temperature systems. When forging,  the metal’s grain pattern becomes more refined with increased impact and strength.

  • Stainless steel angle bar stock needle valve
    Stainless Steel Angle Bar Stock Needle Valve

    Stainless steel angle pattern needle valve bodies where the fluid takes a 90-degree turn.

    The bar stock is known as billet. The bar stock needle valve back seating provides added sealing protection.

  • Stainless steel forging angle needle valve
    Stainless Steel Angle Forging Needle Valve

    Stainless steel forging integral needle valves enhance the material’s resistance to shrinkage, cracks, and porosity, which are common happened in high-performance environments.  It has increased the strength and durability of the forged fluid systems.
