DN32~DN250

◆ TPF…Series flow controller with integrated control valves are primarily applied in center air conditioning auto-control and heating systems.
◆ Adopt straight stroke proportional type actuators, flow output characteristic: equal-percentage flow/equal-linear flow.
◆ Dynamic equilibrium introduces design project of bellows balance.
◆ Actuator input signal: 0~10VDC, 2~10VDC, 0~20mA, 4~20mA(by setting switched S2, S3 on the actuators.
◆ Actuator output signal: 0~10VDC, 2~10VDC, 0~20mA, 4~20mA(by setting switched S2, S3 on the actuators.
◆ High valve shutoff differential pressure, small leakage rate. Matched with "Kvs remote adjuster", can realize djustment of Kvs value of valve(set range:30%~100%), Kvs value remote adjuster type: TKVS-1.
