Product Features:

This is a conventional rising stem valve with a downstream sealing structure and a disc spring at the valve seat, providing good performance at low pressure. It features a single seat, with the valve seat seal consisting of an outer diameter non-rubber seal with an actuating spring + a rectangular face seal, and a disc spring for low-pressure assistance. The valve stem seal is designed with a spring-actuated pressure non-rubber seal. The valve has a pressurized cavity and can be repaired online without special tools. Metal seals are used between the valve plate, valve seat, valve body, and valve cover. It is available in manual and actuated versions, with actuators including hydraulic cylinders, gearboxes, or electric actuators.
