product usages

J61Y welding straight-through pound class high temperature and pressure power station globe valves is suitable for the pipelines of ANSI Class1500 ~ 3500Lb, working temperature -29 ~ 570 °C oil, chemical, fire station and other working conditions, used as cutting off or connecting media. Applicable medium: water, steam and so on. operation modes are: manual, gear transmission, electric and so on.

Product structural features

1. Product design and manufacture according to ANSI B16.34, E101 standards, can be equipped with imported equipment.
2. Middle cavity uses pressure self-tight sealing structure, the higher the pressure in cavity, the better the performance is. Disc and seat sealing surface uses Stellite cobalt-based hard alloy welding. The depth of the bonnet stuffing box is reasonable, packing plus inhibitor, sealing is reliable, open and close is stable.
3. The valve has upper sealing structure to ensure that there is no leakage through the stem when the valve is running.
4. The open and closure of the valve is controlled by the electrical device, electric devices are equipped with a special motor, reducer, torque control mechanism, on-site operating mechanism, hand, electric switching mechanism. In addition to local operations, it can also carry out long-distance operation.
