Robo Drain No-Loss Drain Valves

Robo Drain No-Loss Drain Valves

$0.00
Pneumatically Controlled, Non clogging ball valve, 0 - 750 psi

The ROBO DRAIN is the ultimate demand operated drain. The unit is fully automatic, no electricity is required. Its low profile gives you the advantage of installing it in areas where the vessel to be drained is only a few inches from the ground. The ROBO DRAIN's design also eliminates the need for the installation of a vent line for most applications.

Benefits:

  • • Zero air loss during the condensate discharge
  • • No electricity required to operate the drain
  • • Operates on demand
  • • Ideal for oil/water separators
  • • Simple to install

Features:

  • • See through vessel
  • • Fully pneumatic
  • • Medium pressure up to 250 psi
  • • Low profile for optimal placement
  • • Non-clogging ball valve
  • • No strainers to clean

Design

The ROBO DRAIN is the ultimate demand operated drain. The unit is fully automatic, no electricity is required. Its low profile gives you the advantage of installing it in areas where the vessel to be drained is only a few inches from the ground.

The ROBO DRAINs design also eliminates the need for the installation of a vent line for most applications. A unique air valve design uses a magnetic force to ensure both a positive opening and closing that will prevent any air loss. The magnetic force is cleverly positioned away from the condensation level to prevent any attraction of metal particulate.

An innovative ball valve support and positioning system prevents the side-loading problem which otherwise would cause premature sealing failure around the valve stem. Rifle drilled discharge porting ensures that scale and rust will exit through a full ported 1/2" ball valve. The ROBO DRAIN will not clog ---- no strainer required.

How it Works

How the Robo Drain Drain Valve Works

  1. Condensation enters through one of two ports
  2. The see-through vessel allows visual inspection of the condensate as it fills the reservoir.
  3. A stainless steel float rises with the condensate and positions a magnetic force over the valve housing.
  4. When the liquid level reaches the desired level, the magnet in the valve housing snaps upward and opening the pilot compressed air valve.
  5. This compressed air is used to actuate the air cylinder causing it to extend and open the ball valve.
  6. Condensation, scale and rust particles rapidly exit the unit. Before any compressed air is lost, the float removes the magnetic force from the valve closing the pilot compressed air valve.
  7. A powerful spring returns the air cylinder to its normal position closing ball valve.
