Hp Heater Emergency Drain Control Valve Capacity: 10-50 Kg/hr

We are engaged in manufacturing and exporting excellent quality HP Heater Emergency Drain Control Valve to our valuable clients. The 60W00 Series HP heater emergency drain control valve is a high flow and large size special control valve used in HP heater emergency drain systems that require good sealing performance. It adopts the pilot type structure. When emergent opening of the valve is needed, the actuator drives the stem to first open the small plug (pilot-operated plug) and realizes fast pressure relief in the valve cavity. The small plug continues to move and drives the large plug to open. The trim surface is subjected to hardening treatment, reaching a hardness of about HRC70. It is featured by good erosion resistance and long service life. The valve is used for HP heater draining in thermal power plants and can also serve as a deaerator level control valve. The HP heater drain control valve can be pneumatically or electrically controlled.
