Bray butterfly valve torque chart
WebThere are three torques to be considered when selecting the proper actuator for a butterfly valve. (1) Seating Torque - The torque required to displace a resilient seat and effect shutoff. (2) Bearing Torque - The torque required to overcome friction forces on the valve shaft bearing surfaces WebCare should be taken when installing a butterfly valve adjacent to lined pipe, as-cast fittings, or schedule 80 plastic pipe. In some cases the disc in the opened position will interfere with the adjacent component. Butterfly valves should be installed a minimum of six (6) pipe diameters from other line components. This is not always practical

Webvalve torque. The initial ball/seat torque of the valve is results of the seats preload (determineby the designer), and the seat material.
