Description
The main advantages of jet drives compared to pneumatic hydraulic and pneumatic piston drives:
the exception of the second agent working the damper fluid;
no moving friction seals;
ability to work on real transported gas, regardless of its pollution and humidity;
elimination of arbitrary rotation of the output shaft under the influence of external load on the part of
the valve;
smooth running over the entire range of working gas loads and pressures;
accelerated reverse of the drive output shaft from any end or intermediate position;
the possibility of creating high pulse time, provides a moving tube of the ball valve with its "welding".
Technical parameters:
Working agent compressed air class 5 according to GOST 17433-80 natural gas according to OST 51.40-
83
Electrical power consumption, W, not more than 35
Feed gas pressure, MPa (kgf/cm2) 1,0-16,0 (10 -160)
Control signal voltage, V 24; 110; 220
Ambient temperature, °C - 60 to + 50
The upper value of relative humidity
at a temperature of 35o C, % 95
Gas consumption during shutter rotation, N. m3, not more than 0,8
Overall dimensions, mm 980x660x655/td>
Weight, kg, not more than 240
Service life before decommissioning, 30 years
