Setting range 0 2 1 0 bar. This ensures automatic flow limitation independent of pressure variations in the system. Red bronze cusn5znpb rg5 valve cone dp material. 003h6283 1 acc.

The timer in the safety circuit is activated when the effective lubricating oil pressure the oil differential pressure the difference between the oil pump pressure and suction pressure is lower than the set value. Av p a due to a normally closed valve and af p a due to a stretching spring. 1 at temperatures above 150 c only with seal pots see accessories the controller is a self acting differential pressure controller primarily for use in district heating systems. Dezincing free brass.

Differential pressure controllers in the primary system are mainly used to keep a constant and lower differential pressure across a motorized control valve or a total system substation. As a rule of thumb the differential pressure controller should be used whenever the ratio between maximum and minimum available differential pressure from the network is larger than 2. Controllers are normally closed. Differential pressure controllers automatically ensure dynamic hydronic balancing in the district energy network water flows through a supply network according to the principle of least resistance.

The timer is deactivated when the oil differential pressure is more than the set value plus the contact differential. 1 a differential pressure controller maintains fixed differential pressure over the flow restrictor flow control. Differential pressure controllers in the primary system are mainly used to keep a constant and lower differential pressure across a motorised control valve or a total system substation. Primarily used to limit a pressure a or differential pressure pa over a system substation pump.

Thread 1 avp dn 15 controller. Pressure nominal bar 16 bar. As a rule of thumb the differential pressure controller should be used whenever the ratio between maximum and minimum available differential pressure from the network is larger than 2. Differential pressure controller pn 25 avp return and flow mounting adjustable setting data sheet ordering example 1.

The controller closes on rising differential pressure.
