Quadra-Powr X Spring Diaphragm Rotary Actuator
Brand: MetsoExclusively developed for quarter-turn valve service, Quadra-PowrX Spring-Diaphragm Actuators provide safe and reliable operation even when minimal supply pressures are available. Yet they are capable of operating at pressures as high as psi: 100 (kPa: 700, bar: 7).
These units can be operated by air, gas, water, oil, or other supply media compatible with the ductile iron/carbon steel casing of the actuator and the Buna-N diaphragm reinforced with polyamide fabric.
Quadra-PowrX torque outputs range from 15 to 796 Nm (11 to 587 feet-pounds), depending on actuator selection and available supply pressure.
