Importants info about Valve systems Slide-flap valves:
Valves: Ball Valves: In the middle there is a hole. Valves, control valves: Shut-off control valves regulate the flow or shut off completely. With positive pressure opens a valve. Self-closing valves: prevent backflow, flow only in one direction. Pressure Reducing Valves: High pressure is reduced to working pressure (gas bottle). Angle valves: There is a diversion by 90.Poppet valve: a spherical body, horizontal partition, liquid flow is 2x diverted ? high pressure loss. Angle Seat Valve: located directly in the pipeline. Self-closing valves: Check valves: mechanical closes when liquid comes from the wrong side. Check Valve: Spring loaded, opens the return spring at high pressure, the liquid comes. from the other side valve is closed.
