What is it: It is a type of valve that provides on-off and throttling control of flow in a compact structure in large pipe diameters.
How it works: The disc (flap) rotating in the center regulates the flow rate by positioning it on the flow section; it is suitable for automation with an actuator.
Where Used: HVAC, fire lines, water-waste water, sea water, general industrial processes.
What are the dimensions: DN50–DN1000; generally PN10–PN16; disc/seal material EPDM, NBR, PTFE etc. depending on the fluid.
