Technical Details and Operating Principle of Sanhua Components

Each Sanhua component used in the refrigeration cycle is designed to control, direct or shut off the refrigerant at a specific point. Sanhua ball valves are valves that provide two-way flow, contain a ball with a bore, and are moved to the fully open/fully closed position by turning a quarter turn by hand. With a low leakage rate, high pressure resistance and long-life PTFE (teflon) sealing elements, they play a critical role at service connections, isolation and maintenance points.

Sanhua solenoid valves (MDF series) control the flow by raising or lowering the piston with magnetic force when an electric current flows in the coil. Thanks to their pilot-operated diaphragm design, they provide high flow control with low power consumption. Check valves (YCVS series) allow one-way flow; by preventing gas from flowing back when the compressor stops, they preserve system efficiency and compressor life. Electronic expansion valves (EEV — DPF series) precisely adjust the superheat value with a stepper motor controlled needle valve design; compared to a classic thermostatic expansion valve (TXV), they provide 15-25% higher COP (coefficient of performance). Sanhua's DPF series EEVs offer linear control between 0-500 steps and work perfectly with inverter compressors in chillers and heat pumps.

Sanhua Models and Types

The Sanhua portfolio is divided into four main families to meet all flow control needs of refrigeration system engineering:

SBV(M) Series Ball Valves: With ODF (Outside Diameter Flare) connections from 1/4"–4 1/8", in versions with or without a service port. Example: Sanhua SBV(M)-A21YHSY-2-SA 2 5/8" ODF, 305 m³/h flow, two-way straight type.
MDF Series Solenoid Valves: With brazed or flare connections, with AC 220V or DC 24V coils. Example: Sanhua MDF-B03-25H004 1 3/8" brazed, 10 m³/h flow.
YCVS Series Check Valves: L type and straight type, 46 bar maximum working pressure. Example: Sanhua YCVS31-DDGSHC-2 with 42 mm connection, 29.1 m³/h flow.
DPF Series Electronic Expansion Valves: With S03 stepper motor, 5/8" brazed connection, superheat controlled. Example: Sanhua DPF(S03)4.0C-01 and DPF(S03)5.5C-01.
Four-Way Valves (4-Way Reversing Valves): Switch between cooling and heating mode in heat pumps.
Angled Filter Driers and Sight Glass Components: Complementary product family.

On Yedepa.com, both small-diameter (1 1/8") and large-diameter (2 5/8") models from these families are in stock. By choosing the diameter that matches the system's flow-pressure curve, professional users both minimize flow losses and extend equipment life.

Which Sanhua Model Should Be Chosen for Which Situation?

Sanhua components are selected according to the nominal capacity of the system, the refrigerant type, the working pressure and the line diameter. The table below can be used as a decision matrix:

Application	Recommended Sanhua Model	Connection Diameter
Small-capacity split AC service valve	SBV(M)-JA9YHSY-1-SA	1 1/8" ODF
Medium-capacity VRF/VRV indoor unit line	SBV(M)-JA11YHSY-1-SA	1 3/8"
Large chiller main line isolation	SBV(M)-A21YHSY-2-SA	2 5/8" ODF
Liquid line shut-off (solenoid)	MDF-A03-20H003 / MDF-B03-25H003	1 1/8"
High-flow liquid line shut-off	MDF-B03-25H004	1 3/8"
Preventing backflow at compressor discharge	YCVS26-99GSHC-1 / YCVS31-DDGSHC-2	1 1/8" – 42 mm
Inverter chiller EEV control	DPF(S03)4.0C-01 / DPF(S03)5.5C-01	5/8" brazed

Particular care should be taken in refrigerant conversions: when changing from R22 to R410A or R32, Sanhua components designed for a higher pressure class (at least 45 bar PS) should be preferred. For flammable refrigerants such as R290 (propane), it is mandatory to choose ATEX compliant series.

Sanhua Component Selection Criteria and Professional Tips

When choosing the right Sanhua component, the following criteria should be evaluated carefully:

Nominal Flow (m³/h): A valve with a capacity 15-20% above the system's design mass flow should be chosen.
Maximum Working Pressure (PS): At least 45 bar is required for R410A and R32, and 90+ bar for R744 (CO₂) systems.
Connection Type: Brazed, flare or ODF; should be determined according to the installation on site and ease of fitting.
Service Port (Schrader): In the SBV series, models with the "JA" code have a service port; this makes measurement and charging operations easier.
Coil Voltage: For solenoid valves, the 220V AC / 24V DC distinction; it must match the control voltage in the panel.
EEV Number of Steps: The step protocol compatible with the chiller controller (Carel, Danfoss EKE, Alco) should be checked.
Leak-Tightness Class: Compliance with ARI 730 and EN 12284 standards should be required.

A tip from field experience: on Sanhua ball valves, when closing, always set the handle parallel to the flow direction and in a position where it does not touch the body; otherwise vibration of the handle will damage the stem threads over time. When brazing, wrapping the valve body with a wet cloth or heat-absorbing gel protects the PTFE seal.

Maintenance and Usage Recommendations for Sanhua Components

The average life of Sanhua valves specified by the manufacturer is over 15 years under correct installation and regular maintenance. However, incorrect practices can halve this period. It is recommended to follow the maintenance protocol below:

Annual Leak Check: The ball valve stem seal and the lower sealing area of the solenoid coil should be scanned with an electronic leak detector.
Solenoid Coil Temperature: Coils that rise above 80°C should be replaced; overheating shortens insulation life.
EEV Stepper Motor Test: Once a year, a fully open-fully closed test should be performed by sending an "init" command from the controller.
Check Valve Disc Check: The rate of pressure drop in the high pressure line should be monitored while the compressor is not running; a drop of more than 1 bar in 5 minutes indicates disc wear.
Filter Drier Replacement: Sanhua valves alone cannot protect the system; the filter drier must be renewed after every major intervention.
Evacuation: After installing a new valve, a 2-hour vacuum down to at least 500 micron should be pulled.
