Drive Mode Of Valve Actuator
- Jun 13, 2017 -

Characteristics of Valve Actuator

Strong applicability, not affected by ambient temperature

Wide range of output torque

Easy to control, can freely use DC, AC, shortwave, pulse and other signals, Valve Control Actuators so it is suitable for amplification, memory, logical judgments and calculations, etc.

can achieve Super miniaturization

Mechanical self-locking

Easy installation

Easy Maintenance

Choice of Valve Drive mode

The choice of Valve drive mode is based on:

The form, specification and structure of the valve.

Valve opening and closing torque (pipeline pressure, valve maximum pressure difference), thrust.

Maximum ambient temperature and fluid problems.

Usage and usage times.

Opening and closing speed and time.

Stem diameter, pitch, rotation direction.

Connection mode.

Power source parameters: electric power supply voltage, phase number, frequency, pneumatic pressure of gas source, hydraulic pressure.

Special considerations: Low temperature, anti-corrosion, explosion-proof, waterproof, Valve Control Actuators fire protection, radiation protection.

Classification of drive modes for valve drives

According to the movement mode of driving mechanism, the valve drive device is divided into two kinds of straight stroke and angular stroke.

According to the drive structure, the valve drive device is divided into:

Valve transmission mode
