The K301 valve, characterized by top-guide, has streamlined fluid passage and owns the features of simple structure, mass flow and reliable capability. Unique design of the cage enables the valve to be applicable to severe services, such as erosion and cavitation. Multi-spring pneumatic diaphragm actuator or electric motor supplies the power of the valves's action. Pipeless connection makes the valve more compact, more convenient to assemble and disassemble, and have higher reliability.
