DAV-P-KA – Dorot Air Valve - KINETIC-AUTOMATIC Function (Combination Valve)

DAV-P-KA – Dorot Air Valve - KINETIC-AUTOMATIC Function (Combination Valve)


This DAV-P-KA has been designed for efficient discharge and intake of air in water transport systems, filtering systems, containers, and other places where confined air could impair the system’s operation.

The valve is appropriate for:

  • Expelling the air at high flow velocity during the initial filling of the systems
  • Introducing large quantities of air when the pipe drains, maintaining atmospheric pressures in the pipe and preventing collapse and cavitation damage to the conduits
  • Relieving the entrained air from the water, while the network is pressurize

Features & Advantages

  • Leak-proof sealing at all conditions, including low system pressure.
  • The aerodynamic design of the float provides air flow at a very high velocity. The float does not close before the water has reached the valve.
  • Threaded outlet elbow allows various possibilities of drain connection.
  • The valve design contains a very limited number of parts, allowing an easy dismantling for maintenance.

Technical Specifications

  • Operating pressure of 0.1 bar / 1.5 psi to 16 bar / 230 psi
  • Maximal water temp. for continuous operation: 60°C / 140°F
  • Maximal water temp. for intermittent operation: 80°C / 175°F
  • 1/2”, 3/4”, 1”, 2” BSP or NPT threaded base - as per the customer’s choice
  • Structure materials: Cover: GRP (UV resistant), Base: GRP or Brass
  • Internal parts: corrosion resistant plastic materials and synthetic rubber
  • At pipe pressure of 0.5 bar / 7 psi:
  • The 2”/50mm valve allows the discharge of    260 m3/h / 153 CFM of air
  • The 1”/25mm valve allows the discharge of    60 m3/h / 35 CFM of air
