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.
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
■ Certified Safety Integrity Level (SIL) per IEC 61508 The ESDV has been evaluated by an independent third party, those that have not been evaluated are relying solely on manufacturers’ product claims
■ Capable of Both Local and Remote Partial Stroke Test Users can minimize system disturbances to prevent and diagnose potential operational problems
We are specialized in Control Valves, ESDV(SIL2&3), On-Off Valve, Pneumatic Actuator(SIL2), Direct Gas Actuator, Gas Over Oil Actuator, Hydraulic Actuator, Damper Actuator, Ball Valves (API 6D. API 608), Solenoid Valve and Accessories.
The Daeju of heavy duty scotch yoke actuators offer a broad range of torques to 250,000 Nm. All the Daeju of quarter-turn scotch-yoke actuators actuators are designed designed and manufactured manufactured for the transmission of high torque suited for ball or butterfly valves, plug etc for on-off or throttling service. The design, engineering and materials used in prod i uct on ensure optimum performances in the heaviest work condition in every environment according to the international standard Specifications. In the central housing a slotted link kinematics provides to transform the linear motion of the rod into the rotary motion of the valve shaft. Our standard offering is the symmetrical design yoke that delivers maximum torque at both ends of the 90° cycle. The square slide bearing with guide bar gives high cycle life and smooth stroke while minimizing wear points. As with all Daeju actuators, our heavy duty series comes with a complete complete line of accessories accessories, including jackscrew, hydraulic overrides, limit switches, solenoids and positioners.
