  • In the food and beverage industry as well as in biotechnology, pharmacy and other areas where perfect cleanliness and sterile valves are required, Flowserve has the solution. Our products meet the USDA and 3A requirements and can be supplied for Clean In Place (CIP) and Steam In Place (SIP).
    Sanitary & Aseptic
  • By using an extended bonnet, the packing, gaskets and seals of ColdFlow valves are protected from cryogenic temperatures, thus ensuring their sealing properties. Optional special gaskets and packing can be used to operate at temperatures as low as -69 °C. Depending on the application, Flowserve cryogenic valves are available with a top entry design for the easy maintenance of valves located in a cold box or with a simple extended bonnet attached to the valve body.

  • The DrainFlow Series 051000 valve is typically used for on-off bottom drain tank applications, where flushing or fluid transfer is necessary. The valve mounts flush to the tank with a plug extending into the tank and with the seat ring flush with the inner wall of the tank. The valve’s compact, lightweight design is ideal for in-line maintenance under the tank. It can be specified with either a 45° or 60° outlet angle. Other options include bellows seal, normalising fins, a special pocketfree body, steam jacketing or a plug that retracts into the body (as opposed to the standard design with an extending plug). The tank flush valve can also be supplied as a control valve.

  • The Valtek GS is a fully integrated valve-actuator-instrumentation package for a continuous process, non-critical flow loop controlled throughout the plant. Engineered from the ground up, the Valtek GS has achieved optimum performance at minimum total cost. It does this by pursuing the simple design philosophy of building an instrumented control valve package that is “everything it needs to be” by providing the breadth and depth of engineered control under the Valtek trusted name.

  • The HPFlow is designed for high pressure applications up to 60,000 psi for very special needs. With the unique split body design it is possible to clamp the seat in between the body parts to handle these extreme pressure ratings. In combination with high pressure there is very often the need to handle also high diferential pressure. In this case the HPFlow series offers an axial multi-stage trim design.
    HP to 60K PSI
  • Many years of experience in the manufacture of lined ball and plug valves and the sophisticated experience of manufacturing excellent reproducible trims for linear valves are combined in this new product. High quality lining materials such as PFA (standard), PVDF, PP, ETFE and FEP as well as PFA antistatic, cover most mediums and applications. The revolutionary PTFE bellows design allows a standard pressure rating of CL150. The increased flow capacity means that the most economical valve can be chosen for the application.
    Fluoropolymer Lined
  • The Valtek Mark 100 control valve is designed to meet the needs of large applications. It offers the highest flow capacity, as well as fast, easy maintenance in both gas and liquid control. The Mark 100 also has longer stroke lengths, providing finer control and resulting in superior process control in smaller valve sizes.
    High Capacity CL150-600
  • The Valtek® Compressor Anti-Surge Valve from Flowserve represents a revolutionary solution to anti-surge control by combining precise control and exceptional responsiveness in a simple, reliable package. It protects compressors from catastrophic surge damage by providing exceptional response for driving the valve open when needed and in a steady-state position when in recycle. Key components: • Mark 100SC™ angle body valve • Logix 3800JF™ positioner • MegaStream™ noise control • Stealth™ noise control • Linear piston actuators • Actuator cushions • SpiralTrack™ feedback
    Compressor Anti-Surge
  • The Mark 200 is one of the most dynamic Flowserve control valve offerings designed to meet the needs of high-pressure large capacity applications. It offers the highest flow capacity, as well as fast, easy maintenance in both gas and liquid control. The Mark 200 also has longer stroke lengths, providing finer control and resulting in superior process control in smaller valve sizes.
    High Capacity CL900-1500
  • The Valtek Mark Eight control valve features a unique Y-style globe body that provides higher flow capacities and less process turbulence than conventional globe valves.
    Y-Pattern
  • The Valtek Mark One globe control valve offers superior performance in liquid and gaseous services, while also permitting easy, fast, and inexpensive maintenance. In standard plug and seat single-stage configuration, the base design provides various design advantages over conventional cage-guided designs. With the ability to be fitted with severe service trims for cavitation, noise, and erosion applications, the Mark One is the most versatile control valve platform.
    Engineered Globe
  • A three-way version of the widely used Valtek Mark One valve, the Valtek Mark One 3-Way valve is used for combining or diverting service. Like the Mark One, it offers superior performance in liquid and gaseous services in simple, rugged design.
    Multi-Port
  • The Mark One-X offers a cost-effective means of installing a small valve in a much larger line without line reducers or expanders. It is identical to a standard Mark One except for its body, which has expanded outlets.
    Expanded Outlets
  • The Flowserve Valtek Mark Six is a globe-style, single-seat, top-entry automatic control valve with a fabricated extension for cold box cryogenic applications to -425°F/‑218°C. Mark Six bodies are constructed of bronze or austenitic stainless steel for high impact strength at low temperature and minimum heat transfer. Mark Six is designed for high flow capacity with a minimum of mass to reduce boil-off on valve cool-down.
    Cryogenic
  • Built from the same basis of design principles as the Mark One but fabricated from bar stock, the Mark Two is an extremely versatile control valve. Due to its constructions, it is available in many different configurations with shorter lead times than conventionally cast valve bodies, even in high-pressure classes or special alloys.
    Barstock Body
  • Kammer SmallFlow micro flow and low flow valves are designed for applications in a Cv range from 0.000063 to 4.7. The have high rangeability and reproduceable trim characteristics. Standard designs as well as special applications or materials available.
    Micro Cv
  • The Kammer TotalFlow (Series 035000 & 335000) is a general service valve portfolio designed to include special configurations. Designed mainly in special materials such as Hastelloy, Alloy 20 or other rare materials, the TotalFlow becomes the solution for your application in any pressure class up to CL2500. For pressure classes up to CL600 it is also available in stainless steel or carbon steel. The series is available as ANSI or DIN and in globe, angle or 3-way valve design. It is a perfect extension to Flowserve‘s FlowTop General Service valve series.
