Valworx 562703C electric actuated soft seated butterfly valve for on-off control of water and other media compatible with the materials of construction. Lug style valve sandwich mounts between standard ANSI / ASME Class 125 / 150 flanges. Standard unit is power-to-open and power to close, stays in last known position with loss of power. On receipt of a continuous voltage signal, the motor runs and via a flat gear system rotates the disc. The motor is automatically stopped by internal cams striking micro switches at both open and closed positions. On receipt of a reversing continuous signal, the motor turns in the opposite direction reversing the valve position.
Butterfly Valve Standard FeaturesRugged epoxy coated (3-layer) ductile iron body with stainless steel disc for maximum corrosion resistance Unique wave line seat and special disc shape reduces the torque required to turn the valve and extends the seal life Lower torque also reduces the size of the actuator, lowering the cost of the valve assembly Two piece shaft design enhances the flow capacity of the valve Valves direct mount to actuator with standard ISO5211 international standards
Electric Actuator Standard FeaturesHighly visible LED light gives continuous actuator status indication Multi-voltage capable with auto-voltage sensing Electronic torque limiter - protects against valve jams without causing damage to the actuator Standard anti-condensation heater Manual override with visual dome style valve position indicator All electrical connections via external DIN plugs (included) - no need to remove cover for wiring or service Two auxiliary dry contact limit switches for confirming open/closed valve position Rugged IP67 dust and watertight enclosure, CE marked
