Explanation of Q-type explosion-proof electric head

Q series valve  electric actuator  is used for small and medium-bore butterfly valves, ball valves and other valves for 90° rotation and other similar equipment. As a stable and reliable quarter-turn Actuator, it can be applied to the needs of different control systems and different working environments. The integrated design of the transmission mechanism makes the product have a smaller volume and a concise appearance. Safe and reliable manual design, fully automatic automatic switching without changing handles. The good degree of protection can meet the needs of a variety of designs: flameproof type, integral switching type, integral adjustment type.

Technical wood parameters

Optional power supply: AC220-660V, 50, 60Hz (to be said when ordering)

2. Ambient temperature: -20°C~+60°C,

3. Relative humidity: not more than 95% (at 25°C.)

4. Working environment: ordinary type is used in places without flammable, explosive and strong corrosion media: the use environment of the explosion-limited type is an explosive gas mixture of A, WB class T1 and T4 groups

5. Protection level: | P657 (special order P6.)

6. The motor is a working system; Rated run time 10 minutes. Class F insulation

7. Anti-corrosion coating: high-temperature baking paint

Installation and removal
The valve  electric actuator  is allowed to be installed at any position, but it must be noted that the motor is in a horizontal position as much as possible, and the electrical box cover is horizontally and vertically upward, which is conducive to lubrication, commissioning, maintenance and manual operation.
