SMO 254 Valves belong to the ASTM a182 specification which covers the high temperature high pressure components. These valves can perform in applications such as heat exchangers, boilers, super heater element pipelines and in other high temperature pressure applications as well. The 254 smo valves are made up of an austenitic stainless steel grade that is also known as the 6 moly grade. The material is strong, corrosion resistant and temperature resistant. There are different types of valves made in this material grade and are used for different functions. The 254 smo ball valve is one of the most commonly used type of valve in this grade.
SMO 254 Ball Valve
ASTM A351 gr.ck3mcun Check Valve
UNS J93254 Gate Valve
It is used in domestic, commercial and industrial applications to regulate the flow of liquids by means of a ball moving in and out of the valve body. The 254 smo gate valve is a different type that uses a gate to regulate the flow.
The gate is connected to a threaded stem. The threaded stem is connected to a handwheel. The handwheel is rotated and the stem rises or lowers with the threads pulling and pushing the gate in and out of the seating. As the gate is fully in the seating the valve is closed and when the gate is fully out of the seating, the valve is open. These valves avoid the water hammer effect. The 254 smo steel check valves are used to control the unidirectional flow of material. They do not allow for a backflow.
