FRL - Filters, Regulators and Lubricators

1. With the operator mechanism turned counter-clockwise, each time the pressure falls below 0,3 bar, [4.35 psi] the condensate will be released; when resetting the pressure, the drain will close again.
   
2. The release can also be carried out manually; when the bowl is pressurized, the operator mechanism is pushed upwards.
   

To stop the discharge of condensate, the operator mechanism is turned clockwise to completely close the drain.

The auutomatic drain model discharges the condensate each time the maximum permissable level in the bowl is reached.
This version should be used where there is likely to be a large amount of condensate or where the system is always pressurized and the semi-automatic drain would not be used.

Normally open at 0 psi (closes at 3 psi), then opens by liquid level to drain so long as within operating pressure range (22 psi - 220 psi)

The depressurization drain allows the rapid removal of condensate at each air consumption of the system.
A pressure drop of 0.1 bar (2 psi) is sufficient to obtain the release of a small quantity of air or condensate present at the bottom of the reservoir, after which the drain is closed.

Normally closed at 0 psi, opens at pressure drop > 2 psi, (Δp=0.1 bar), so long as within operating pressure limits of 4.5 - 145 psi.

The depressurization drain allows the rapid removal of condensate at each air consumption of the system.
A pressure drop of 1 bar (14.5 psi) is sufficient to obtain the release of a small quantity of air or condensate present at the bottom of the reservoir, after which the drain is closed.
This version has a filtering element which protects the outlet holes from any impurity.
Normally open at 0 psi, closes at 4.5 psi, then opens with pressure drop > 14.5 psi, (Δp=1 bar)

This version permits connection of external items to the bowl via a through hole of Ø 3mm and a threaded port 1/8".

Application example:
Mounted mini valve series A (or ball valve) for remotely operated drain.
