Shut-off valves / Angle shut-off valves Advantages - Recommended 1) Recommended for use as a throttle 2) True bubble-free shut-off if equipped with a resilient seat. 3) Suitable for frequent operation Shortcomings 1) Significant pressure drop in the process 2) Cost is higher than other types of valve High disc and seat structure 1) Elastic (soft) seat disc is the preferred structure. But for high-temperature piping systems, high-precision throttling, or fluid media with abrasive and other applications, the alloy metal is a better choice. PTFE is the best resilient valve material for most pipe systems, but rubber is more flexible in cold water environments. 2) Plug-in disc / seat: Metallic alloys with high hardness are commonly used. They are particularly suitable for applications where precise throttling is required and the fluid medium temperature exceeds the Teflon temperature limit (260oC) or the fluid includes abrasive. Cast iron stop valves are usually semi-insert bronze disc / seat structure. 3) Automatic steam cut-off check valves and angle cut-off valves are suitable for medium-pressure steam piping systems where the sliding action of the semi-plug-in disc allows the valve to function as a shut-off valve, throttle valve and check valve.
