Emergency shutdown valves

Reliable intelligent emergency shutdown (ESD) valves and actuators with Neles™ ValvGuard™ intelligent valve controllers improve your plant safety cost-efficiently. At Valmet, 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.

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.

Digital hydraulic concept reduces cost and increases reliability

By using digital hydraulics, fragile and expensive proportional valves are replaced with multiple inexpensive and robust on/off valves. The results include higher reliability, lower energy usage, more accuracy in machine movements, fewer shutdowns, less lost production and lower initial investment and spare parts carrying cost.

Ready for the challenge: Valves enhance fluidised-bed polymerization

The global olefins market is expected to grow by about 4% or more in the next several years. The packaging and automobile industries are ...

Flowrox valves control sludge flow in a wastewater plant without problems

Flowrox pinch valves PV 500 E01 are successfully controlling the sludge flow in a Polish wastewater plant. Twenty electrically actuated valves were delivered in 2011 to Poland through Danish engineering company Krüger A/S and local Valmet Flow Control channel partner.

Common hydraulic valves – cartridge counterbalance valves

Counterbalance valves prevent oil from leaving a cylinder that is holding a load. Without them, loads would move uncontrollably if oil pressure is lost.

Intelligent solenoid valves: slash time and costs with knowledge

When a refinery in South America was approaching its scheduled three-year maintenance shutdown, it decided to take advantage of the information provided from its intelligent solenoid valves. Earlier, the refinery had decided to install these valves on every emergency shutdown (ESD) valve to identify degradation by using partial stroke testing (PST) for these critical valves.

Delivering reliability down the line

Oil and natural gas pipelines crisscross North America; in the US alone, approximately 150 000 km of gathering and trunklines span the ...

Common fluids valves explained: Pressure reducing valve

Pressure reducing valves are used to create and hold a pressure setpoint in a downstream hydraulic branch. Valmet uses sandwich style valves because they are easy to fit in a stacked hydraulic valve block circuit.

Solenoid and air operated valves

Our solenoid valves and air operated valves are all based on modern designs and communication technologies. We offer a comprehensive range of spool type direction control valves for actuation in various pneumatic applications. The range includes all types of direction control valves required for process automation.
