Torque closes valve used multi-turn electric actuator/highly sealed in close position

Multi turn valve actuator is a micro valve actuator that elaborately designed and manufactured by the most advanced technology, it mainly assemble with gate valve. This gate valve disc is wrapped in rubber that could cause deformation and compensation action to attain good seal effect, avoid leaking, rusting. It is widely us in water supply, building, petroleum, chemistry, food, pharmaceuticals, light textile, electrical, shipping industry, metallurgy, energy systems.

Features

• Over torque protection type valve closing instead of turns setting type valve closing
• Rugged IP67 and type 4X aluminum alloy enclosure
• Corrosion resistance with thermally bonded polyester coating
• Torque can be set and adjusted by internal potentiometer on mini control board
• Turns can be set and adjusted through Hall element position
• 2 LED lights with different colors to confirm valve position
• Continuous mode and inching mode available
• CE marked/RoHS 3.0 complied

Description

DCL-MZZ multi-turn electric actuator uses over torque protection type to close valve to make sure valve is fully sealed. Since diaphragm valve and small globe valve linear move by rotate drive, and these valves commonly need to be sealed by an over normal torque which is like screwing cap to a bottle.

So for closing direction, an large over torque protection is set, to make sure valve is totally sealed. While, we can see that if the torque of the closing direction and the opening direction is the same, then valve can not be opened, which is also same as that when unscrewing the cap from a bottle, we need even larger torque than screw it. So the opening direction over torque protection is 1 second later than motor starts moving to avoid motor stuck on the fully close position.
