J762Y Hydraulic 4 way globe valve manufacturer, factory and supplier. J762Y Hydraulic 4 way globe valve automatic protection device equipped with the high pressure heater to ensure that when the high pressure pipe system leaks, or the trap adjusting door is stuck and other abnormal conditions, the valve will automatically close the water supply to the high pressure pipe system and open the bypass water supply. Since the high pressure heater is designed to cut off the water supply, a set of water side protection valve is designed.
J762Y Hydraulic 4 way globe valve Main model specifications:Model: J762Y, J962Y, J761Y, J961Y; Nominal diameter: DN 175,225,275,300 mm;Nominal pressure: PN 20.0, 25.0, 30.0mpa. J762Y Hydraulic 4 way globe valve is installed at the entrance of the high pressure heater. When the high pressure heater fails and the water level exceeds the allowable water level, the water supply is switched to bypass in an emergency to ensure the safe disconnection of the high pressure heater, thus protecting the high pressure heater.
J762Y Hydraulic 4 way globe valve feature:
1. Full hydraulic control system: fast action, and the fastest switching time can reach 2S.
2. Electric inlet valve and electric outlet valve can also be selected: the operation time is slightly longer, but two pneumatic quick opening valves can be omitted to simplify the system design.
3. Hydraulic cylinder with damping cone, protect the system pipeline and valve seat from impact.
4. The valve body form is Z type or Angle type, and the bypass direction can be adjusted in the range of 180 degrees.
5. Body is cast or solid forging, material: WCB, A105 or WB36(15NiCuMoNb5). The WB36 valve body is more suitable for supercritical and higher pressure units.
