Limitorque's LPS heavy-duty pneumatic scotch yoke actuator is the innovative, reliable choice for on/off, inching and modulating automation applications on quarter-turn medium-to-large sized valves in general and protective services for the oil & gas market. LPS actuators provide up to 550 kNm (405 659 ft-lb) of heavy-duty torque. Enhanced performance is achieved by using a superior Scotch yoke support design that significantly reduces transverse loads. LPS actuators feature modular construction to minimize repair time and initial cost while maximizing process availability. -
The Limitorque LPC series is a compact pneumatic scotch yoke actuator for on/off, inching and light modulating applications on quarter-turn small-to-medium sized valves in general and protective services for the oil & gas market. Equipment performance and safety standards continue to evolve and increase across the infrastructure industries. These stringent demands are particularly dynamic in oil and gas, where perpetually increasing emphases on personnel safety and equipment uptime is the norm. To more aggressively meet these demands, Flowserve Limitorque is offering the LPC Pneumatic Compact Scotch yoke actuator, specifically designed to meet or exceed the latest and most rigorous of these requirements. -
Ever since its introduction back in the 1980s, NAF Turnex has proven its unique features and maintenance-free operation. The robust linkage system with bushing provides an optimum torque curve for quarter turn valves and eliminates play. This makes it ideal for rotary control applications. NAF Turnex is an integrated part in the NAF control valve package with a unique direct mounting concept. The actuator is also used for on/off service and has adjustable end-stops in both directions. Ever since we developed this state-of-the-art actuator the spare parts have been the same. This, combined with a unique system of sleeves, for different stem diameters, minimizes the number of spare parts. -
The DFS series scotch and Yoke Pneumatic Actuators are heavy-duty actuators for operating large diameter ball valves, butterfly valves, plug valves and other 90˚ rotating mechanism. Available with two yoke deigns namely symmetrical design and canted yoke design. Cylinder blocks are plated with hard chromium to increase the service life of the actuators. The piston rod and guide block connection superior surface finish and the self-lubricating bearings maximize the input energy transfer directly to the valve stem and ensure reliable operation over the service life of the actuator. Can be supplied with the complete line of controls and monitoring accessories, including hand wheel, hydraulic manual override, limit switches, solenoid valves, positioners and other control accessories. -
The Limitorque LRP provides durable functionality and prolonged service life through unique features such as piston support rods within the actuator, ensuring that side loads generated by the pistons are transmitted through bearings in the end cap and not the body. This eliminates the need for the body to be used as a loadbearing surface and promotes longer service life. The support rod design of the Limitorque LRP actuator distinguishes it from the standard rack and pinion design and offers reliable operation, performance stability and longer service life. -

The Logix 520MD Series digital positioner combines superior positioning and tuning functions with convenient setup and powerful diagnostic tools. The Logix 520MD positioner uses a multi-variable gain tuning algorithm which allows the positioner to make large step changes with minimal overshoot while achieving the resolution to respond to very small step changes. The Auto-tune procedure cycles the actuator to produce a measured response and selects gain values that provide appropriate actuator performance. The Auto-tune function includes a gain modifier selector that can be used to increase or decrease the calculated gain in order to achieve optimal performance. Easy DIP switch configuration for tuning mode and other common settings. For custom settings, tuning sets can be modified with a handheld or with ValveSight software, to accommodate a wide range of actuator sizes and types. -

The unique ring disc design ensures that the disc remains light and responsive even in large sizes, which is essential for rapid non-slam closure. Mounted on a multiple spring and radial guide assembly, the disc moves freely without the frictional forces. Combining two ring-shaped annular flow paths with the excellent pressure recovery properties provided by the diffuser, the minimal pressure drop across the Type N valves gives lifetime energy savings when compared to more conventional check valve designs. Pressure recovery is further enhanced within the NG series due to a wider split-body design to facilitate greater flow efficiency and throughput performance. -
Noreva's NZ is specially designed for gas applications having a centrally guided, single spring with very low fully open velocity. The design is focused on laying the centre of gravity of the only moving part, the disc, over the centre of the surface it is sliding on. Due to this design change, the NZ is able to use softer springs, which function at very low flow rates, mainly because the tilting effect of the moving component is eliminated all together. It provides the same internal flow profiles and consequentally, the same pressure loss. -

The Valtek Mark Four Tek-Check, non-slamming piston check valve, provides rugged performance and reliable service in corrosive and non-corrosive, gas and liquid applications. The smooth, nearly-constant area internal passages allow for high capacity flow with minimum turbulence. When the flow ceases or is reversed, the piston closes slowly, preventing pressure surges. The non-slam design is also effective in dampening pulsating flow.
