Frese

Chilled water designers specify Frese valves to hold the flow through each coil steady while pressures in the network change. The Danish maker, founded in 1944 and based in Slagelse, works in dynamic balancing and control valves. Seven Star LLC lists the Frese OPTIMA Compact pressure independent control valve, DN 10 to DN 50, and supplies Frese valves to HVAC contractors in Oman on inquiry.

Chilled water designers specify Frese valves to hold the flow through each coil steady while pressures in the network change. The Danish maker, founded in 1944 and based in Slagelse, works in dynamic balancing and control valves. Seven Star LLC lists the Frese OPTIMA Compact pressure independent control valve, DN 10 to DN 50, and supplies Frese valves to HVAC contractors in Oman on inquiry.

Frese OPTIMA Compact and where Frese valves are used

The OPTIMA Compact combines flow limitation, differential pressure control and modulating control in one body, which is what the term pressure independent control valve describes. The manufacturer serves three markets: HVAC in buildings and industry, district energy from production to consumer, and marine and offshore, where corrosion-resistant materials are used. Recent documents from the manufacturer may carry the Vexve name alongside Frese.

Ordering Frese valves: what we need

Send the article number, or the size, the connection type, the design flow rate and the flow range version. For the actuator we need the control signal, the supply voltage and whether a fail-safe function is required. GCC project teams can send the valve schedule and we match each line to the manufacturer data.

Frequently Asked Questions

How is a Frese OPTIMA Compact valve identified?
The valve body and the packaging label carry the article number, the DN size and the flow range. Sizes share bodies with different flow inserts, so the size alone does not define the valve. Send the article number or the design flow per valve from the schedule.
What does pressure independent mean for a control valve?
The valve contains a differential pressure regulator that keeps the pressure drop across the control section constant. The flow then depends only on the control position and the preset maximum, not on pressure changes elsewhere in the system. This removes the need for a separate balancing valve on the same terminal unit.
What actuator data is needed with a Frese PICV?
State the control signal from the controller, such as on/off, 3-point or 0 to 10 V, the supply voltage, and the closing behavior needed on power loss. The actuator has to match both the valve size and the control system, so send the controller output details with the valve list.
Is Seven Star LLC a distributor of Frese?
No. Seven Star LLC is an independent industrial supplier based in Muscat. We source Frese valves and actuators through commercial channels, check the model or order code against the manufacturer's documentation, and provide the manufacturer's datasheet and the certificates the manufacturer issues with the order, on request.
