Imported high pressure and emergency drain regulating valve
The American YLOK imported high pressure emergency drain control valve is a special control valve specially used for large flow, large diameter and good sealing performance such as high pressure emergency drainage system. The pilot structure is adopted. When the valve needs to be opened in an emergency, the actuator drives the valve stem to first open the small spool (pilot spool), so that the pressure in the valve cavity is quickly relieved, and the small spool continues to run to drive the large spool to open. The surface of the valve trim is hardened, with a hardness of about HRC70, erosion resistance and long service life; the valve is used for high-pressure drainage in thermal power plants, and can also be used as a deaerator water level control valve. The high pressure trap valve can be pneumatically or electrically controlled.
