GAS-OVER OIL ACTUATOR

Application
90°angle stroke , emergency shut-off ball valve of transmission pipeline of natural gas ,ESD shut-off valve.

Features

Patented parallel , double-guide scotch yoke box provides angel type valve with bigger open torque.

Parallel , double-guide rod could withstand horizontal load and give support to the piston rod.

The bearing with composite structure provides a reliable and stable operation , and extending the life of the actuator .

Pistons bearing reduces the friction between the piston and cylinder wall , the cylinder can achieve self-lubricating effect.

The guide rod is produced with high strength and anti-corrosion coating.And this could reduce friction to a minimum value.

Cylinder wall is designer with features of high strength and anti-corrosion and reliability.

Design of internal guide rod brings about more compact cylinder structure.

Design of fully enclosed and weather-proof carbon steel body brings about rugged and reliable structure:internal coating will provide anti-corrosion feature.

External limit bolts may be adjusted in the full stroke range of 90±°.

Based on low hysteresis and quick response , the actuator is also suitable to be used to operate control valve.

With various canted and symmetric type of scotch yoke , actuator could be used to operate different type of valve.

For offshore and high corrosion condition , special coating could be offered.

For sour gas condition , special designed actuator could be offered.
