FORGED STEEL VALVES
GATE - GLOBE - CHECK
GATE VALVES are used for on-off operation on hydrocarbon , general process, and utilitie service for all temperature ranges.
GLOBE VALVES are used for flow regulation or as a block valve where high resistance to flow is not a disadvantage and a positive closing action is required.
CHECK VALVES are required to permit forward flow and prevent reverse flow. this is achieved through linear or rotary ( angular) motion of a closure member which is kept open by flowing fluid.
When the flow is reduced towards zero, or reversed, the closure member is moved against its seat by forces due to gravity, supplementary springs and back pressure.
