ARI-CONA 665 (AWH)

Liquid drainer PN16 / PN40

Description

eClass-No.:	37019090
Application:	For automatic condensate-discharge during start-up and operation
Medium:	Steam, condensate, etc.

Scope of applications
Automatic liquid drainers with thermal control are used to drain off condensate during system start-up and shut-down.

The information complies to the Pressure Equipment Directive 2014/68/EU.
It is the responsibility of the machine planner to ensure compliance.
The special markings on the valve must be taken into account.

Operating principles

(refer to Fig. 3)
The automatic liquid drainer drains condensate from steam facilities during the start-up of a process.
When the set closing pressure is reached the valve shuts automatically.
When the system shuts down or closing pressure is not reached, the valve opens and automatically takes over residual drainage.
When the system is unpressurised the liquid drainer is held in the open position by the builtin spring (Pos. 24.5). It shuts as soon as the operating pressure has risen to the set closing pressure (due to the pressure differential effective at the valve area versus spring resistance).
If the operating pressure drops below the closing pressure it opens due to spring resistance.
The liquid drainer is supplied as standard with a factory-set closing pressure of  1,5 bar
