GF-PICV-02

The GF-PICV-02 is a two-way pressure-independent control valve, DN15 to DN25, Kvs 1.0 to 3.0, with a thermoelectric or motorized actuator fitted on the body. It goes on fan coil, chilled beam and AHU branches, and on district cooling substations, one per terminal. A terminal balanced at handover drifts off its design flow by the afternoon, and the actuator keeps opening to make up the difference. The flow holds at the setting, and riser pressure stops deciding it.

The diaphragm reads the differential across the orifice and balances it against a spring. When riser pressure climbs, the regulator closes and the differential stays put, so the flow follows the plug position alone.

Maximum flow is set on the scale with a wrench, in five positions. Position 5 is full open and 1 the minimum; the table gives 490, 1000 or 1800 L/h by size at position 5.

Thermoelectric actuator at 77 to 90 N, 45 or 70 seconds. Motorized at 100 to 150 N, 45 or 120 seconds, Modbus RS485 on request. Both run on 230 V or AC 24 V, IP65.

Standard body material: brass CW617N (CuZn40Pb2; EN 12164 / EN 12165).

Other grades: HPb59-1 (GB/T 5231) and CW602N dezincification-resistant brass. Both are available on request and must be stated on the order. We do not substitute a different grade without your written approval.

Minimum order quantity: applies to all three grades.

Lead content: all three are leaded brass. CW617N carries 1.6–2.5% lead, and HPb59-1 carries 0.8–1.9%. For potable water, confirm the lead-leaching limits of the destination market before ordering.

Material certificate: EN 10204 3.1 on request. The grade stated on the certificate governs.
