Features:
The output of torque is constant, which can ensure the same output torque and constant when the cylinder swings clockwise and counterclockwise.
Constant volume design structure, without loading any valve group and stem can realize constant speed control;
Extremely low starting pressure and special sealing structure can achieve high frequency;Highly responsive job requirements;
The very low internal calorific value is worth improving the working efficiency;
Protection class IP68, suitable for use in environments filled with soil, dust, moisture or offshore platforms;
Internal zero leakage, can accurately maintain any position;
It can provide a variety of installation connection forms, such as foot installation, flange installation, non-standard installation hole, etc.
The core parts are made of high-strength alloy steel, hardened and polished.
High transmission efficiency and high reliability;
The terminal can optionally install position feedback switch and other position detection elements;
Adopt world famous brand seals;
Spiral swing cylinder with low starting pressure and low friction can be provided.
Application:
Automatic control, water engineering, sewage treatment plant, chemical and pharmaceutical industry, air conditioning and ventilation, industrial ships, industrial solar energy, thermal power plant, solar thermal power plant, biogas power plant, exploration (water, coal, gas, oil, nuclear) offshore plant, oil refinery, oil pipeline, oil depot, etc.
