Emergency shutdown valves
Improving availability with field proven reliability and advanced diagnostics
Reliable intelligent emergency shutdown (ESD) valves and actuators with Neles™ ValvGuard™ intelligent valve controllers improve your plant safety cost efficiently. In Neles we have combined our know-how of valves, actuators, safety standards (IEC61508/61511), applications, system operability and partial stroke test devices with intelligent prediction tools. Diagnostic information is presented understandably to enable planned maintenance of potentially failing valve assemblies before they have a chance to impact the process or safety.
Benefits
Single-source supplier for demanding ESD valve assemblies
Field-proven, certified technology gives accurate reliability figures for the final element in your safety loop
Partial stroke testing provides increased availability and safety protection
Emergency shutdown valve offering
Butterfly valves
Neles™ butterfly valves are designed to truly optimize the efficiency of process operations by offering best-in-class valve capacity. They provide long-lasting tightness and industry-leading valve reliability, certified to SIL 3. Our product range includes both metal and soft-seated and rubber-lined butterfly valves.
Ball valves
Neles ball valves are designed to meet the requirements of the process industries with improved process safety and efficiency. Our proven technology in design, materials and coatings enhance process reliability in the most demanding shut-off and control applications. For control applications our ball valves provide famous Q-trim™ technology for noise attenuation and cavitation prevention. A wide range of product certifications include fugitive emission, fire-safe and SIL 3.
Pneumatic actuators
Neles™ double acting and spring return quarter-turn actuators are designed for use both in modulating control and on-off service. These actuators offer an extremely long cycle life and are well suited for almost any type of rotary valve.
Intelligent safety solenoids
Neles ValvGuard is a top class intelligent safety solenoid with partial stroke testing features for emergency shutdown and venting valves. Based on the automatic PST and other diagnostics data, VG9000 increases safety and plant safety targets can be reached more economically than with other solutions.

How to choose control valves
Control valve requirements often differ depending on the process area, application and end user specifications. Process conditions and the range of parameters also vary widely, including pressure, temperature, controllability, cavitation risk, environmental impact, noise and more. Plus, priorities may differ. An end user may want to know more about a valve’s performance, controllability and total life-cycle cost, whereas an EPC contractor may be more concerned about the CAPEX-related costs and delivery times. How do you know where to start – and where to turn for help with quality information you can rely on?
