Basic Types - by function

Valves can be categorized also based on their function

  • [Check valve] or non-return valve, allows the fluid to pass in one direction only.
  • [Flow control valve], to maintain and control a variable flow rate through the valve
  • [Poppet valve], commonly used in piston engines to regulate the fuel mixture intake and exhaust
  • [Pressure Reducing Valve], to regulate the pressure of the fluid.
  • [Thermal expansion valve], used in refrigeration and air conditioning systems.
  • [Safety valve] or [relief valve] : operates automatically at a set pressure to correct a potentially dangerous situation, typically over-pressure
  • [Sampling valve]
