A solid wedge is the commonest & commonly employed disk kind due to read more its simplicity and strength. A valve with such a disk could possibly be set up in almost any placement, and it truly is ideal for Practically all fluids. It can be utilized in turbulent flow also. Having said that, it does not compensate for changes in seat alignment as a consequence of pipe masses or thermal growth. So, such a disk layout is most prone to leakage. It can be subjected to thermal locking if used in more info superior-temperature support.
Stem: A rod that is definitely related by a disc from a single end and one other aspect connected to the hand wheel.
