QP745Y/X Hydraulic equalizing spread valve
Purposes and Features:
1. Suitable for the BF stove top pressure equalizing system, use as furnace top equalizing relief valve.
2. Soft and hard seals through hard alloy and silicon rubber;,valve plate has a self-centering function, reliable seal.
3. Valve is sealed upon the action of medium pressure and hydraulic cylinder in the process of closing.
4. Valve disc can far from the brushing of the medium when the valve is opened.
5. Main material: quality carbon steel.
Executive Standard:
1. Flange connection dimensions carry out the provisions of GB/T9119-2000.
2. Pressure test refers to the provisions of GB13927-2008.
Note: Use other standards according to customer's requirements, but please mark out while placing orders.
