Check Valves - (1951 companies)Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. Fluid flow in the desired direction opens...Valve TypeSevere Service RatedBack Flow Preventer Assembly -
Flow Orifices and Flow Restrictors - (133 companies)Flow orifices and flow restrictors contain precision-machined holes and filters or screens to restrict flow and reduce pressure. They are available as stand-alone devices and in kits, assemblies, restrictors, and restrictor valves. Flow orifices... -
Control Valves - (1646 companies)...components alter the flow rate so it is no longer determined by the geometry of the valve body and disc. The flow rate is altered by resistances resulting from pipelines, orifices, or other equipment in series with the control valve. For a linear valve... -
Globe Valves - (794 companies)...23. Self-actuated valves use the system fluid to position the valve. These are commonly found in relief valves, safety valves, check valves, and steam traps. Because these actuators use the fluid in the system, no external power is required... -
Air Valves - (794 companies)...include stopping and starting flow, throttling (control) flow, and acting as a non-return check for flow (check). Stop/Start valves are used for systems that do not need the flow throttled. The valve opens to allow the flow and closes to stop flow... -
Hydraulic Valves - (684 companies)...of Hydraulic Valves. Hydraulic valves can be almost any valve, i.e., check valve, drain valve, control valve, and many more, as long as the valve restricts hydraulic fluid they can be classified as hydraulic valves. For a full description on types...
