How does an SV / SVS series butterfly valve work ?
A butterfly valve is used within a processing line and can be in two states.聽 The open state allows flow and the closed state shuts-off flow in the line.聽 The valve opens and closes by turning a disc 90掳 which can be performed manually or remotely using a pneumatic actuator.聽 The pneumatic actuator opens the disc by way of compressed air and closes the disc by spring force.聽聽
