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.
Condensate pumps are used to collect and transport condensate back into a steam system for reheating and reuse, or to remove unwanted condensate from an HVAC or appliance collection pan.
Pressure switches are actuated by a change in the pressure of a liquid or gas. They activate electromechanical or solid-state switches upon reaching a specific pressure level.
