Flow Controller with Integrated Control Valve
  TPF25-2VGC-1000XS...TPF150-2VGC-3000XS
view larger size ·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 (by setting
    switches S2, S3 on the actuators).
·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:40%~100%), Kvs value remote adjuster type: TKVS-1.
