Pneumatic Linear Actuators

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.

Emergency Shut Down Valve

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.

Emergency Shutdown Valves Safety Features

■ Tight Shut Off With a double-seated design, ESDV’s are rated up to ANSI Class VI shutoff providing bubble tight shutoff.

■ Fire Safe In the event of an emergency, your assets may be exposed to fire, all ESDV’s are rated to API 607 Fire Safe.

■ Fast-Acting Quick response is critical to reducing escalation of hazards, ESDV’s can go from full-open to full close in less than a second.

■ Manual and Automatic Release Options Users have flexibility on resumption of system operation after shutdown.

■ Rugged Design Designed to withstand shocks and vibrations that could cause false trips, ensuring your systems is up and running when it needs to be

■ Customizable Configurations Several unique configurations can be engineered to meet your specific application’s needs

Mounting Unit SIWAREX WL270 CP-S SB

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.
