Sanhua DPF3.0 Electronic Expansion Valve – DPF(TS1)3.0C-29

Sanhua DPF3.0 Electronic Expansion Valve – DPF(TS1)3.0C-29 is a compact electronic expansion valve for precise refrigerant-flow modulation in air-conditioning, refrigeration and reversible heat-pump systems. Sanhua lists this exact valve as DPF(TS1)3.0C-29. Under the catalogue rating condition (Tc 38°C, Te 5°C, SC 0°C and SH 0°C), its nominal R410A cooling capacity is 32.5 kW and its Kv is 0.39 m³/h.

Product overview

The DPF-TS/S family uses a direct-acting permanent-magnet stepper motor to position the valve electronically. The family provides 500 full-stroke steps and supports bidirectional refrigerant flow, making it suitable for systems where operating load and refrigerant direction can change. Electronic modulation allows the controller to adjust valve opening from live system inputs rather than relying on a mechanical thermostatic power element.

Why choose DPF3.0?

DPF3.0 sits at a specific point in the DPF capacity range: it combines a Kv of 0.39 m³/h with catalogue nominal capacities of 27.8 kW on R22, 21.7 kW on R134a, 28.6 kW on R407C, 19.4 kW on R404A/R507, 32.5 kW on R410A, 47.7 kW on R32 and 28.8 kW on R290. This makes model-level selection important; two DPF bodies that look similar should not be treated as interchangeable without checking capacity, pressure differential, coil/driver requirements and the complete valve code. For a smaller DPF capacity step, compare DPF2.4. For a larger DPF capacity step, compare DPF3.2.

Compatible coil for DPF3.0

The coil must be matched to the valve body and controller. For this DPF3.0 configuration, the catalogue identifies the PQ-M10 coil family. Do not select a coil only by appearance.

• Standard PQ-M10 / XHP-5: PQ-M10012-001059 (700 mm), PQ-M10012-001016 (1500 mm), PQ-M10012-001002 (2000 mm).
• Pre-wired epoxy-potted options: PQ-M10012-004002 (700 mm), PQ-M10012-004274 (1500 mm), PQ-M10012-004213 (2000 mm), PQ-M10012-004035 (5000 mm).

Applications

• Air-conditioning systems with electronically controlled refrigerant metering.
• Commercial refrigeration equipment.
• Reversible heat-pump systems requiring bidirectional flow.
• Systems requiring accurate superheat or refrigerant-flow control through a compatible electronic controller.
• Applications where load varies widely and active valve-position control is useful.

DPF electronic valve vs thermostatic expansion valve (TXV)

A thermostatic expansion valve such as the Danfoss T2/TE2, TR6 or TGE uses a mechanical thermostatic power element to regulate superheat. The Sanhua DPF instead uses a stepper motor and an electronic controller. A TXV can be simpler because it does not require an EEV driver and electronic sensing strategy; the DPF gives the control system direct command of valve position and is especially useful where load varies, tighter electronic control is required or refrigerant flow reverses. These technologies should not be treated as direct replacements without engineering selection.

DPF vs other electronic expansion valves

DPF should also not be selected merely by comparing physical size with another EEV. Different electronic valves can use different step counts, motor drive methods, pressure limits, flow coefficients and controller requirements. For comparison, SYREF also lists Danfoss ETS 12C electronic expansion valve and Danfoss ETS 100C electronic expansion valve. A Sporlan SEHI/SERI or another Sanhua EEV may serve a similar control function, but compatibility must be established from capacity, refrigerant, MOPD, connection size, controller output and motor specification—not from the generic term “electronic expansion valve.”

Selection and replacement notes

Before ordering DPF(TS1)3.0C-29, confirm the complete model code, refrigerant, required capacity, evaporating and condensing temperatures, subcooling, superheat, pressure drop, flow direction, connection dimensions, controller/driver output and the required PQ-M10 coil configuration. For replacement work, verify the existing controller’s motor-drive compatibility before assuming the valve is a drop-in substitute.

Installation notes

Sanhua specifies the coil in the upward position with the rotor central axis within ±15° of vertical. The inlet is preferably arranged sideways and the outlet downward. Follow the current manufacturer installation instructions and system cleanliness/brazing practices when installing the valve.
