Control.

  • 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 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
  • 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.
    General Service
  • The unique Survivor control valve design solves the harshest erosion, corrosion and flashing applications. With a variety of ceramic trims available, no other valve will last longer, even in applications with demanding flashing and erosive particulate. The unique design of the Survivor directs flashing energy away from critical equipment. Unique packing configurations solve difficult sealing problems associated with solids entraining the process fluids.
    Multi-Phase Expanded Angle Letdown
  • TigerTooth control valve trim creates multi-staged pressure drops that are effective in reducing noise and vibration in gas services and in eliminating cavitation in liquid services. TigerTooth effectively reduces noise and vibration in gas services by up to 35 dBa through staging, attenuation and velocity control. TigerTooth uses multi-stage pressure drops to eliminate cavitation in liquid services.
    Multi-Stage Stack Noise Reduction Trim
  • Stealth control valve trim reduces control valve noise and vibration in the most demanding gas applications. Stealth combines new advances in noise control with previously proven technologies to create the most effective device capable of eliminating noise in the most demanding services. In addition to reducing the pressure gradually, Stealth takes advantage of frequency shifting by providing small outlet holes which raise the frequency and lower the noise.
    Multi-Stage Stack Noise Reduction Trim
  • MegaStream control valve trim reduces control valve noise and vibration in a wide range of gas applications. MegaStream works to reduce noise by up to 30 dBa through staging, frequency shifting, attenuation and velocity control. With decades of proven experience, the MegaStream control valve is the one of the most common solutions to control valve noise.
    Multi-Stage Cage Noise Reduction Trim
  • The NAF Torex, High-Performance butterfly valve is available with either metal-to-metal or soft seats. Due to its unique design and triple offset, it closes extremely tight. It can be used both as a control valve and as a shut-off valve.This valve can be supplied in either wafer or lugged versions. The valves are also available in other materials e.g. Carbon steel, and Titanium, other stainless steel materials and in Fire-safe design.
    Triple Offset
  • The Valdisk TX3 is a high performance triple offset butterfly control valve capable of closing with zero leakage. The precision seat and seal are machined at an offset angle creating even seat loading around the entire seat ring and eliminating rubbing between the seat and seal during opening and throttling. This design provides repeatable long-lasting zero leakage shut-off.
    Triple Offset
  • The Valtek Valdisk BX is a double offset butterfly control valve designed to meet the most routine and the most rigid service requirements. Adopted from Flowserve's Durco BX product, the Valdisk BX offers a proven design and variety of configurations for seating, packing and materials.
    Double Offset
  • The Valtek Valdisk valve is a high-performance butterfly control valve. Its double-offset shaft provides eccentric-cammed disc rotation to lift it out of the seat, thus immediately eliminating seat friction, to improve throttling control and reduce seat wear. A one-piece splined shaft connected to a clamped actuator lever provides excellent throttling control. Its soft seating arrangement is designed for bubble-tight shutoff while maintaining low breakout torque.
    Double Offset High Cv
  • The MaxFlo 4 is a high-performance eccentric rotary plug control valve. The flow path is unobstructed by the shaft, allowing higher capacity for a given valve size. This noncrossover shaft design also eliminates shaft damage from erosive process fluids. The shaft is designed per ASME B16.34 Section 6.5 to prevent the stem from being removed while the valve is under pressure for increased safety.
    Eccentric Plug
  • The NAF Trunnball DL is a full-bore trunnion-mounted ball valve, developed by Flowserve engineers with more than 80 years of experience manufacturing ball valves. The ball is supported by two large, low friction trunnion bearings for consistent low torque even at high differential pressures. Due to its bi-directional tightness, low friction and high controllability, it is an excellent choice for isolation, on/off and modulating control applications.
    Full Port 2-Piece
  • The NAF Duball DL Ceramic is a ball valve that is internally lined with ceramic for erosive and abrasive media. It is primarily intended for control but has a sealing class as for a shut-off valve. The valve represents a concrete result of our product philosophy which is focused on functionality, high quality and low life cycle costs, and is based on concentrating our range to a limited number of valve types, but all of them suitable for a wide variety of applications.
    Ceramic Lined
  • The NAF Duball DL Pocket Valve is the pulp and paper industry’s choice for a reliable and robust valve solution that allows for safe removal of sand or debris in separator and junk trap applications during normal process operation. Building on years of experience in providing flow control solutions in harsh environments, the Duball DL Pocket Valve is specifically designed to ensure continuous process uptime and throughput by allowing process pressure to be maintained while unwanted process particles are eliminated.
    Full Port Pocket
  • The Duball DL is a high-performance, metal-seated, full-bore ball valve, equally suitable for isolation, on-off and modulating control applications. The excellent characteristics of NAF Duball DL are particularly beneficial under the most challenging operating conditions in the process industry, where difficult media and demanding pressure conditions make severe demands on the design, materials and performance.
    Metal Seated Split-Body Full Port
  • Valbart designed the Trunnion Mounted Control Ball Valve (TMCBV) to operate at high pressures while minimizing the torque needed to operate the valve. The spring-loaded, process energized seats offer tight (Class IV and Class V) shutoff at any pressure. In most cases, the TMCBV's capacity is greater than that of a comparable globe valve. This allows the customer to use a smaller, lighter valve and experience cascading savings. This valve also requires a smaller, less expensive actuator and less expensive pipe supports.
    Trunnion Mounted Ball Control
  • NAF Setball ProCap Segmented Ball Valves are unique high-tech capping valves designed for automated filling of wood chips for batch digester applications in the pulp industry.
    Capping Valve
  • The NAF Setball for Middle Consistency (MC) pulp is a ball sector valve with metal-to-metal seating and combines the best control characteristics of the ball valve and the butterfly valve. It can be used both as control valve and as shut-off valve and is available in flanged version. This valve type is developed for MC-pulp 8-19%. It has an enlarged outlet with one size bigger flange on the outlet to get an excellent flow characteristic for the MC-pulp out of the valve. It is available as standard in 1.4408/CF8M, CG8M and SMO254.
