• Reliable and Robust • Variable flow proportional to the control signal • Long service life • High flow due to angled seat design • Anti-water hammer design (fluid entry under the disc) • Actuator rotatable through 360˚ • Fail-last position • Fluid isolation between electrical actuator and valve body • Vacuum service up to 7 x 10-3 Torr • RoHS 2 compliant • Ideal for “Lead Free” applications • 24 VDC feedback signal• Cost Savings • Actuator automatically initializes when power first applied for quick & easy start-up • Plug-in electrical connector saves installation time and cost• Fast Response Time • Less than 1.3 seconds to open and again to close, significantly quicker than electric quarter-turn ball valves • Shorter cycle provides more responsive control which yields increased throughput and higher quality end product• PLC Integration • Compatible with standard I/O 24VDC • Easily connects to fieldbus networks• Energy Savings • Consumes less than 2 W holding/setpoint position • Consumes only 12 W during opening/closing • Eliminates the need for an external air supply• 360° LED Position Indication • LEDs allow users to easily identify valve position and status
