High Temperature Technology

High temperature & high pressure power valves are the key piece of equipment used in the power generation industry. As process temperatures increase in the new design generation systems, high alloy valves are required I the main steam, auxiliary steam and water supply systems.


In accordance with the industry standards for power valves like ASME B16.34, Chinese standard, JB/T3595 and Japanese standard E101, Sanseco has successfully developed a full series of power valves including gate, globe and check valves. Sanseco Group has developed over 300 patterns, available sizes range from DN15 to DN600 (1/2"~24"), pressure rating from PN200 to PN320 (1500~3500LB), primary materials WC6, WC9, C12A, F11, F22, F91. These valves are designed to serve the super critical applications.


Sanseco’s high temperature & high pressure power valves are designed and manufactured so as to get reliable shutoff and easy operation under a high temperature environment. Optional internal body cavity relief (pressure equalization) provision prevents over-pressure conditions. The specified bolt torque is maintained during the valve assembly by specialized torque limiting equipment to prevent valves from leaking between the valve body and bonnet and get the reliable long-term operation once the valves are put into service.
