Linear Actuator consists of one pneumatic single acting cylinder designed to operate linear valves as globe or gate valves which require a fail-safe action to close by means of spring return. Linear Actuator is designed and manufactured so as to operate in the heaviest work condition in every environment according to ISO specification. Typical features are the particularly simple and reliable construction, the special care in components material selection in order to reduce corrosion phenomenon. Linear Actuator can be supplied with helicoidal springs. For long strokes and low thrusts (gate valve) helicoidal springs are preferred.
The Emergency Shutdown Valve (ESDV) controls process media flow and is responsible for isolating the supply of hazardous gasses and fluids within the pipeline in the event of an emergency. As a result, these valves provide more reliable performance than standard on-off valves.

The bending ring load cell is particulary suitable for implementation in container, conveyor and platform scales.
Due to its high resolution this load cell can also be adapted to batching applications or legal-for trade scales.
SIWAREX WL280 RN-S SA meets as standard feature the accuracy class C3 according to OIML R60.
The load cell material is stainless steal and fulfills the degree of protection IP66 and IP68, therefore it resists even unfavorable environmental influences.
WL280 RN load cells with a rated load up to 13t are additionally equipped with integral overload protection.
Due to its low installation dimensions the load cell can be applied to a wide range of applications.
The huge number of mounting accessories like self-aligning bearing, elastomer bearing, guide elements, etc. facilitates the various use and provide a secure installation as well as an optimal flow of forces.
The compact mounting kit SIWAREX WL270 KE CP-S SB makes it easy to mount the load cell and allows for safe and reliable operation.
The mounting kit and the load cell are made of stainless steel and both can be installed in aggressive environments. The mounting kit is delivered pre-assembled and it can be used as a mounting “dummy” for your application. As the load cell is at this point not included it is possible to undertake welding or other installation work without risk of damaging the load cell. Inserting the load cell is child’s play: First release the clamp allowing you to insert the load cell. After that, the clamp can be tightened – the load cell is now fixed. Last step is to lower the load carrier, which is done via hex-nuts in a very safe and controlled way.
The design is self-aligning and allows horizontal displacements up to 8 mm. Additional safety features include the integrated overload protection and lift lock. If the load cell is damaged in any way, it can be replaced by lifting the top plate of the mounting kit and exchanging the load cell.
