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.
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).
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.
Over the years Flowserve has accumulated vast experience in developing special features on control valves and dedicated products for specific applications. Flowserve’s engineering departments around the world operate as part of a network so the customer can be confident that the solution we provide is the best design with regard to his specific demands. Flowserve’s experience means that we are recognized as one of the leading companies to provide technical solutions for process control for critical applications.
The FlowTop control valve is a high-performance, general application valve coupled with the high-thrust FlowAct pneumatic diaphragm actuator. The modular design allows you to use the same body with different types of bonnets, trims and actuators. This leads to the reduction of spare parts and offers an interchangeable valve for a broad range of industries and applications.
The Valtek FlowTop GS control valve (types V746 and V748) improves the reliability and uptime of production processes while minimizing operating and maintenance costs. Designed for general service applications, the FlowTop GS globe valve is a competitively priced, fully integrated valve-actuator-instrumentation package for continuous process flow loop control throughout the plant.
High pressure applications up to 60,000 psi or PN 4000 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.
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.
The Valtek Mark One globe control valve offers superior performance in liquid and gaseous services, while also permitting easy, fast and inexpensive maintenance. The spring-cylinder actuated Mark One valve provides stiffness and maintains high positioning accuracy, repeatability, controlled high speed, and faithful response.
The Valtek Multi-Z axial flow control valve eliminates cavitation often associated with high-pressure drops. It is ideal for applications in the power generation, oil and gas, and chemical industries where there are extreme pressure differentials (including those with entrained solids) and in services where high rangeability is required.
Valves with pressure classes above PN40 or ANSI Class 300 are considered by Flowserve as "high pressure" designs. Based on decades of proven experience and expertise, Flowserve can supply the best high-pressure control valves on the market with pressure classes up to PN4000 / ANSI Class 4500 and above.
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.
