Wafer Electric Butterfly Valve , DN50 DN65 DN80 Electrically Operated Butterfly Valve
OVERVIEW
The BFS series of butterfly valve has a 316 Stainless Steel body, PTFE coated 316 S.S disc and a PTFE coated EPDM seat making them suited
to a wide range of high end applications. These wafer butterfly valves will fit all standard flanges and are operated by a high quality IP67 electric actuator which includes visual indicator, manual override and extra limit switches (available in all voltages). The unique bonded catridge design gives them a longer life span, allow vacuum to be run through them and makes them replaceable if ever the need should arise. Common applications include food industry, chemicals, pharmaceuticals and other industrial applications. If sizes above 300mm are required please contact us.
The VA16 series is equipped with standard On-Off or modulating (4~20mA, 1~5V, or 0(2)~10V ) control quarter-turn electric actuator.
FEATURES
• Wide size range (DN 50…DN600)
• For On-Off or Modulating Control
• The handwheel assembly manual adjustment
• Irreversible worm gear.
• Visual mechanical position indicator for accurate visual reference of valve position.
• Anti-condensation heater and 2 aux. limit switches on standard model
• Enclosure IP67
