The Valtek NT 3000 Series Electro-Pneumatic Transducer is an active I/P Transducer that is used with a milliamp electricl control signal. It is interchangeable with the XL Series or Beta Series Pneumatic Positioners and can be mounted on either Valtek Linear or Valtek Rotary Actuators without modification.
CavControl valve trim lowers cavitation damage by controlling the location and concentration of cavitation vapor bubble implosions in an area away from metal parts. CavControl trim utilizes a number of small, diametrically opposed flow holes through the walls of a special seat retainer.
CavStream valve trim lowers cavitation damage by controlling the location and concentration of cavitation vapor bubble implosion in an area away from metal parts. CavStream trim utilizes a number of small, diametrically opposed flow holes through the walls of a special plug.
DiamondBack trim prevents cavitation from forming and minimizes hydrodynamic noise even in the most challenging liquid applications. Staged pressure drops eliminate cavitation by maintaining pressure above the vapor pressure, never allowing cavitation to form. DiamondBack combines new advances in pressure drop management with previously proven technologies to create the most effective device capable of eliminating cavitation in the most demanding services.
SideWinder trim prevents cavitation from forming and minimizes hydrodynamic noise in high pressure drop, low flow applications. Staged pressure drops eliminate cavitation by maintaining pressure above the vapor pressure, so that cavitation never forms. Using the proven DiamondBack advanced pressure drop mechanisms in an axial flow configuration producing precise control in low flow conditions.
The StarPac 3 offers repeatability, accuracy and quick system response time with a small footprint and simple installation. It can stand alone or be integrated into a system, and is available for a variety of applications including oil and gas, chemical, paper, mining, industrial gases and power generation. Unique to the market, StarPac intelligent control systems give users an integrated view of the process at a single point and can improve plant operation at a lower installed cost than conventional control systems. The StarPac 3 builds on previous designs.
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.
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 Mark 100 is a large control valve designed to meet the needs of large applications. The Flowserve Mark 100 globe control 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.
