About the Company
*** Has cast iron body; stem and sealing seat are made of stainless steel.
*** Lowering the minimum torque force allows the opening and closing of the valve by single operator.
*** While the open-close torque of the valve with gearbox decreases, the number of turns needed to open-close the valve increase.
*** Attention should be paid on the connection dimensions and gear- box ratio when selecting an actuator for the valve.
*** The DN dimensions and gearbox types mentioned on the table are given according to the general applications.
*** It is advised to receive support from FAF Valve technical staff while selecting gearboxes.
*** Most of the valves require an operator torque that can only be achieve with a gearbox. There are part turn and quart turn manual actuators.
*** Manual actuation is usually drove by handwheels. Valves whose ac- cess location makes difficult to operate on them can be drove by chain wheels.
*** For security, the driver can be out of the gearbox spigot.
*** Only authorized operators who bring the handwheel or wrench nut with them can operate the valve.
