Butterfly valves may be used to regulate, or control flow in combustion systems. The models found on our site allow some flow even when 100% closed. Butterfly valves can be found on both gas and air lines in combustion systems. The “butterfly” part of the name actually refers to the rotating disc connected to a rod. The disc may rotate up to 90\u00b0, from fully closed to fully open and all points in between. <\/p>\n\n\n\n

The smooth shape of the butterfly disc produces low torque, and their design makes them easy to install, use, and maintain.<\/p>\n\n\n\n

A butterfly valve is sized based on the flow requirements of a system. Ensuring a proper pressure drop across the butterfly valve provides a suitable control range. You may achieve this drop by using a reduced port butterfly valve in some cases. The reduced port allows you to achieve the drop of a smaller valve without complicating the piping. <\/p>\n\n\n\n

Butterfly valves are also selected based on the fluid temperature. High temperature butterfly valves often have a long stem, to help remove the actuator from the worst of the heat. In extreme cases, heat shields may be employed to deflect the heat away from the actuator. <\/p>\n\n\n\n

Before selecting a butterfly valve, it is important to know the fluid type (air, gas, etc.), the fluid temperature, pressure (PSI), flow, control requirements, and desired pipe connection.<\/p>\n\n\n\n

Elektrogas Valves<\/h2>\n\n\n\n

VF<\/a>, VFT<\/a>, and VFH<\/a> butterfly valves from Elektrogas are made for regulation and control of both gas flow and air flow in combustion processes. These butterfly valves can be operated either manually or automatically.<\/p>\n\n\n\n

Elektrogas butterfly valves are made of aluminum (VF\/VFT) or cast-iron (VFH). They\u2019re suitable for use with air and non-aggressive gases (VF\/VFT), and heated air and flue gas (VFH). The VFH offers low leakage when the valve is closed, due to a disc stop.<\/p>\n\n\n\n

The VFH type is provided with a double-eccentricity disc and a spring to reduce the backlash. This results in a high precision adjustment and avoids valve floating.<\/p>\n\n\n\n
