Catalogue excerpts

Electric EBRO Wafer Butterfly Valve Type: J3-6100-EB Available with actuator function: POWER OPEN - POWER CLOSE FAILSAFE MODULATING Actuator direct mounted Main J3/ J3C Smart electric actuator features: LED light for continual visual actuator status feedback. Actuator housing Fully weatherproof smart industrial actuator, CE marked. Multi-voltage capable actuator , EU manufactured by J+J. Actuator temp limits All external electrical connections, no need to remove cover . Assembly temp limits Thermostatic anti-condensation heater. Valve body Cast Iron, epoxy coated Electronic torque limiter. Valve disc Stainless steel Valve liner EPDM (NBR, Viton, Silicon, GMX option) Valve Pressure rating Valve temp limits Size range Selectable manual override facility. End of travel switches for remote open/ closed indication. Applications: Water, and most non-corrosive media, subject to compatibility with wetted parts in contact with media. Electrical actuators sized on a maximum differential pressure of 10 bar wet service, operated at least once per day. If the intended duty differs from these parameters or is dry (air or gas), call to check JJ actuator sizing as a larger output valve actuator may be required. Maximum working temperature of a direct mounted assembly is +70C. For higher working temperatures , consider models that have a mounting kit between the valve and actuator which uses air cooling to dissipate the rising heat from the valve away from the actuator. Should the J3 smart actuator see more than +70C it will malfunction. Wafer pattern butterfly valve installation information: How this electric 1/4 turn valve works (on-off): Electrically operated valves are driven by a motor and gearbox. On receipt of a continuous voltage signal the motor runs and, via a gearbox in the J+J smart electric actuator, rotates the valve stem. The motor stops at the desired position (usually 0° or 90°) by internal cams striking micro-switches. The smart valve actuator remains in this position, with the voltage still applied continuously, until switched and a continuous voltage reversing signal is applied, which runs the motor in the opposite direction, reversing the rotation until separate set of internal cams strike separate set of micro-switches. Wafer pattern butterfly valves sandwich between two mating flanges, secured by through bolts that pass all the way from one flange to the other, and a corresponding nut. See diagram to the right. The correct alignment of wafer pattern valve so that the butterfly valve’s resilient liner seals against the raised faces of the flanges is aided by through-bolt lugs cast into the wafer valve’s body, although as these lugs are oval in shape to allow alignment with several different flange standards (ANSI, BS, DIN), care must be taken to ensure correct alignment when tightening the through bolts. Wafer butterfly valves are not suitable for end of line service. Uncontrolled copy, not subject to automatic updates.
