HOFFER-HFEV TYPE CONTROL VALVE

HFEV type control valve is suitable for various types of liquid, gas flow control equipment. HFEV control valves are available for a wide range of pipe sizes from 1/2" to 40" (can be expanded to 80"). At present, the control valve is widely used in: manufacturing, mining, petroleum and petrochemical, medicine, electronics, ships, water treatment, data room, building and other production and life fields. HFEV type control valve provides convenience for remote industrial automatic control.

 

2. Technical features:

♦ Wide diameter: 1/2 "-40" (15-1000mm), (can be expanded to 80")

♦ Beautiful appearance, compact structure, convenient installation.

♦90 degrees rotation fast opening and closing, good adjustment performance.

♦ The opening and closing torque is small, the rotating shaft is basically equal to the medium, and the direction of torque is opposite, so the opening and closing is more labor-saving.

♦ Good low pressure sealing performance.

♦ Low fluid resistance.

♦ Powerful function, a variety of control signals and feedback signals for choice.

♦ Worm gear output shaft integrated design, high transmission accuracy.

♦ Safe and reliable, can pass AC1500V voltage test, choose F class insulated motor.

♦ Start and close 20,000 times.
