For example, the R Series and RXP Series electric actuators rotate from 0 to 90 in 2.5 seconds. The three basic control functions available through quarter turn automation are: Learn about the latest IPEX products, new applications and case studies. Should the motor be overheated, it then closes the circuit when the motor reaches a safe operating temperature. The actuators share the same design with the only exception being that one model has springs and the other model does not. The actuators have an extruded aluminum body with die-cast aluminum end caps. Sun Yeh OM series quarter turn electric valve actuators are designed to provide torque ranges from 35Nm to 4500Nm.

They are designed to automate the precise operation of valves that open and close through a rotary 90 motion (a quarter turn), such as ball valves, plug valves, choke valves, dump valves, and butterfly valves.
Diverter Ball Valves All of our switching valves for our mole sieve beds are orbit valves fitted with ATI actuators. To prevent heat damage from overwork or excessive current draw, electric actuator motors are usually equipped with a thermal overload sensor embedded in the motor windings. A self-locking design with a permanently lubricated drive eliminates the need for periodic lubrication and allows for maintenance-free operation over the life of the actuator.

All Rights Reserved. In compliance with ISO 5211, part-turn actuators transmit torque to the valve for a rotation of one revolution or less. LTQ actuators are available in a range of torques from 35 to 2,230 Nm (310 to 20,350 in-lb), operating voltages from 12 VAC/VDC to three-phase 575 VAC, and fail-safe (super-cap and battery backup) options that allow for a higher degree of customization to meet exacting customer needs. ATI linear actuators on 6-inch and 8-inch gate valves have worked flawlessly since put in Y-grade liquid service in 1994. Trunnion Ball Valves The piston and rod seals are made of teflon rings preloaded by an O-ring suitable for the most severe working conditions. Double Acting: 195 through 28,500 in.lbs return pneumatic actuator! Assured Automation. Internal features include a blow-out proof pinion, dual opposed rack pistons and adjustable travel stops. They are the preferred choice when cycle time is an issue, as a quick closing pneumatically actuated valve could cause a damaging pressure surge condition (water hammer). The actuator is required to drive the valve through its entire travel from the fully open position to the fully closed position or vice versa. The design also allows the same basic actuator to be used as a double acting or (with minor additions) a spring return unit.
With resolution figures better than 0.1% and the ability to eliminate position overshoot, the Rotork CVQ helps to maximise product quality and plant capacity. For example, power to open the valve, then power to close the valve. Chemical Processing Each hydraulic actuator is equipped with a manual hand pump and hydraulic oil reservoir. Konrad M. Fontenot, Engineering Section Group Lead, Exxonmobil Beaumont. Power See CVA Range Literature Page for Further Details. When the power is cut, the motor stops. The externally adjustable travel stops are on center with the piston rod, eliminating side loading to the scotch yoke. This type of actuator is quite tough and rugged, and has a high cycle life. Actuation Copyright ATI. Modifications can be made to the actuators to achieve closing speeds as fast as 0.1 seconds. See all of the accessories offered for our water meters. The cylinder walls are electroless nickel plated and precision honed to ensure long lasting, trouble free service.

The clutch-less design enables the actuators to be changed from electrical control to manual operation without a clutch or brake to achieve easier operation thus increasing mechanical reliability and decreasing the failure rate.
Our company has built a reputation as an industry leader in quarter-turn electric actuators by providing a wide range of standard features and benefits, including: Each actuator in our product line offers the highest standard of quality in terms of performance and build quality. All pistons are furnished with a teflon impregnated graphite guide ring (wear band) that eliminates any possible metal to metal contact. 854, Sec. Our diverse line of quarter-turn electric actuators can meet a variety of situations. The most distinctive design is clutch-less manual override (except BM-2 and OM-A). It offers end users high standards in performance, build quality and overall value. A rack and pinion actuator would need four separate pistons and a multiplicity of related air chambers, whereas this is easily accomplished with an electric unit. Optimally positioned, graphite infused, self-lubricating Teflon sliding bands on the piston ensure low friction operation with minimal risk of piston tilt, resulting in low wear.

Pneumatic and electric actuators can be easily fitted on our ball, multi-port, and butterfly valves.
The actuator is required to occasionally drive the valve to any position (fully open, intermediate and fully closed). Pharmaceutical For enhanced corrosion protection in aggressive environments, we also offer optional coatings such as anodic films, epoxy coatings, electroless nickel plating, and chromium conversion coatings for additional passivation and barrier protection. I want to thank ATI for the attention this order has clearly received & I plan to pursue similar solutions in the future with you guys. At ICI we pride ourselves on the quality of our products. As a default, AVCO sizes actuators on an 80 psi air supply, but torque values are provided for other air supply pressures as well. The users determine a proper model per load requirements. Straight forward and easy to understand training materials covering the most important concepts in valve automation. 1, Shatian Rd., Dadu Dist., Taichung City 432, Taiwan. In addition, electric actuators are the preferred (if not the only) choice when a quarterturn valve like a multi-port is used.
They generally have a compact, simple construction, and certain models can be quite light in weight. The only way to change the output speed is to install a cycle length control module. (* indicates required).

The ATI Quarter-Turn Hydraulic valve actuator is ideal for operating valves where utilizing hi-pressure natural gas as a power media presents a safety concern, for instance in a closed environment. The CVQ delivers a range of sizes suitable for almost all quarter-turn control valve applications requiring highly accurate positioning. Also referred to as fail safe open, the default position is open and the actuator requires power to close the valve. Compressed air systems are readily available in any plant, and the cost of the actuator itself is generally lower than that of an electric unit with a comparable torque output. More than 270 Rotork process control actuators have been ordered for an LNG project in Australia.

Easy to Use Most electric actuators have a cam/limit switch arrangement which allows the unit to be set up for a variety of rotations. Weatherproof enclosure to NEMA-4/4X standard. The Quarter-Turn Hydraulic Actuator is designed to operate with pressures up to 1500 psi, providing torque outputs over 1 million inch-pounds. When pipeline pressure is not available, the manual hand pump can be used to safely and reliably open and close the valve at its maximum torque requirement. Read posts about valve applications, case studies, problem/solutions, industry news, and more. Class B: Inching/positioning or positioning duty. Typical quarter turn automation seldom requires positioning (something achieved more easily with an electric actuator), therefore the cycle life of a pneumatic unit will be substantially greater, and will be intrinsically safer than an electric actuator in volatile environments. A multitude of voltages both for AC and DC current are also typically available.
