• Gas driven system
• Storage tank for manual override
• Electrically or mechanically operated
• Large range of operating system is available
• GOV can be installed on DRS, DRV, HYV or any other make of actuators
• All pressure parts are as per PED and available with certification

The valve is cut off when pressure in the line increase above set pressure there by Limiting torque/ force which actuator/ cylinder

Monitor healthiness of up and down stream pressure. Cut off the valve when any of the pressure fails. Once fail the valve can be reset

Life of the Solenoid depends on ambient temperature, duty cycle, temperature rise and class of insulation used for the solenoid. Temperature rise depends on design, current density and insulation system of the coil. Rotex ensures that for all its design of the coil, temperature rise above ambient is less than 70 C

As per IS 4800 standard, insulation system is designed for minimum life of for 20000 Hours When used continuously. Using the half life decay principle, every 10 C reduction of the coil temperature, twice the life can be extra polated. Considering worst temperature rise of the coil at 1.2 times the rated voltage, continuously energized coil shall be less than 70 C. For a ambient temperature of 55 C, the maximum temperature of the coil will be 55 + 70 = 125 C
For a Solenoid having class F insulation minimum life expected shall be as under:
20000 Hours at 155 C
40000 Hours at 145 C
80000 Hours at 135 C
160000 Hours at 125 C

Which means, Life of a Continuously energized Solenoid having Class F Insulation, i.e. (ambient of 55 C) is Minimum of 160000 Hrs ie 18 Yrs.

In case if more life is expected then Solenoid with better insulation or lower temperature rise is to be used (e.g. Low Power Solenoid)

Rotex is leading manufacturer of Valve automation system with almost all sizes of ball valves,
butterfly valves and plug valves for the applications, Valve Automation for Emegency Shutdown / Blow Down applications

There are more than 50000 valve automation systems running in the field.
Huge installations are put up in Oil & Gas, Pharma, Power, Cement and other process industries

We offer High performance Heavy Duty Scotch yoke actuator DRS series with Torque limit up to 830 Nm to 600000 Nm. & Heavy Duty, High Performance, Rack and Pinion Construction series DRC delivering torques from 200 Nm to 20720 Nm.

Life more than 1 million cycles.,
SIL3 capable
End Stroke : +/- 10 Degree
Easy to convert from Double acting to Single acting.

The EHF series has a wide range of applications and is resistant to environmental influence, even in marine environments. The electro- hydraulic actuators are recommended within district heating plants, oil and gas depots where Explosion-proof equipment is required and where pressurized air is not available or unsuitable. Within the oil and power industry, safety is of the highest importance. In emergency situations the failsafe function i.e. close or open the valve automatically with the aid of a return spring in the actuator.

Advantages:

Reduced installation and maintenance costsMost reliable means of positioning a valve in a safe position on loss of power or signalThe actuator is constructed for direct mounting on valves according to ISO-standards.Designed for safety critical applicationsConfirms valve availability and minimises plant shutdownImproved process control and product qualityProvides local operator informationComplete sealing allows calibration and interrogation of the actuator in all environmentsEnvironmental protection maintained for internal components during installation and commissioningInterfaces with a variety of communication networksSuitable for harsh environments including immersion up to 7m
