The new durable and economic FB series of gearboxes are capable of withstanding in excess of three times rated input torque and a lifespan of over 1000 cycles. Also incorporated is an external overload feature to prevent damage to the valve if subject to abuse. All FB gearboxes include electrical switches activated when the valve is moved from the open position.
