The use of ethylene and propylene glycol in a mixture ratio of 25 - 50% by volume [%] is permitted.

Ammonia contained in hemp damages brass valve housings.

EPDM seals are swollen by mineral oils or lubricants containing mineral oil and thus lead to failure of the EPDM seals.

For frost and corrosion protection agents based on ethylene and propylene glycol can be found in the manufacturer’s documentation.

Pursuant to Article 33 of the REACH Regulation (EC No. 1907/2006), we are obliged to point out that the material lead is listed on the SVHC list and that all brass components manufactured in our products exceed 0.1% (w / w) lead (CAS: 7439-92-1 / EINECS: 231-100-4).

Since lead is a component part of an alloy, actual exposure is not possible and therefore no additional information on safe use is necessary.

Field of application

The Pressure Independent Balancing Control Valve (PIBCV) is used in all heating and cooling systems with circulation pumps.

The valve automatically maintains flow to the required part of the system at the set rate by measuring and immediately adjusting to any variation in pressure.

No additional measurements are necessary and the correct flow rate is achieved at all operating conditions.

The diaphragm responds to the pressure upstream and downstream of the regulating valve (via an internal impulse line).

The valve settings directly affect the volumetric flow through the valve.

It is thus possible to set the maximum flow rate based on the flow chart when the valve is fitted.

This allows for the balancing of heating circuits, cooling water systems, ceiling cooling and heating panels, air heaters, etc., without any need to first assess the pressure variations in the system.
