Frequently Asked Question

Do you have any question?

Motorized valve is a power supply to drive the motor rotation, thus opening or closing the valve of a device, and withstand voltage shocks. The rotating range of the electric valve is adjustable. The rotating range can be adjusted by inputting the specified current and voltage signals.

  • Motorized valve is one of the automated valves to help automation easier.
  • The motorized valve uses electric energy as power to switch on the electric actuator to drive the valve to realize the on-off and regulating action of the valve. So as to achieve the purpose of switching or adjusting the pipeline medium.
  • According to the difference of the valve body, it can be divided into: motorized ball valve, motorized butterfly valve, motorized gate valve and motorized globe valve
  • COVNA provides 2 electric actuators for you to choose: Quarter-turn(Part-turn) electric actuator and Multi-turn electric actuator
  • Control Methods: AC/DC power supply, signal control and manual override
  • Voltage: DC-12V, 24V; AC-24V, 110V, 220V, 380V
  • Signal control: 4-20mA, 1-5V, 0-10VDC
  • Seal material: NBR, EPDM, VITON, PTFE and Metal
  • Valve material: Stainless steel 304/316/316L, plastic and cast iron

Motorized valve mechanisms are prevented from advancing too far by using a set of electrical limits which cut the motor supply when a valve is either fully opened or closed. When the valve needs to be adjusted again, the motor's direction is simply reversed to turn the valve in the opposite direction.

COVNA is a motorized valve manufacturer over 22 years in China. We offer motorized ball valve, motorized butterfly valve and motorized gate valve and motorized globe valve for your project. If you have any need about motorized valve, please feel free to contact us.

This little known plugin reveals the answer. Rotary or quarter turn motorized valves are the valve type with the quickest actuation times and typically use a cam or central spindle advance mechanism. These valves are among the most common motorized valve types and include ball and butterfly valve varieties.

motorized-valve | Where the butterfly valve is applicable

{keyword},Butterfly valves are suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipeline is relatively large, it is about three times that of the gate valve.

motorized-valve | How to choose electric butterfly valve

{keyword}.The disc of the butterfly valve is that the disc has a shaft rotating on the position of the valve seat. The angle of the rotation determines the opening and closing degree of the valve.

motorized-valve | Gate valve movement

{keyword},Most gate valves are forcibly sealed, that is, when the valve is closed, the gate must be forced against the valve seat by external force to ensure the tightness of the sealing surface.
