  • Check Valves-Image
    Check Valves - (1944 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. Check valves are self-activating safety valves...

    Pressure Relief Valves - (1003 companies)
    With many of these designs, a helical or hydraulic pressure spring is used to maintain constant force acting on the backside of the valve disk or diaphragm, causing the valve to be normally closed. When the force exerted by the process stream (i.e. fluid...

    Hydraulic Valves - (684 companies)
    Hydraulic valves contain and transfer the flow and pressure of hydraulic fluid in hydraulic power systems. They range from simple shutoff valves to precision control valves. In their unpowered state, hydraulic valves can be normally open (open...
