In pneumatic automation, the solenoid valve is the critical link between electrical control signals and pneumatic actuation. It receives commands from a PLC or controller and directs compressed air to cylinders, actuators, and other pneumatic devices. The reliability, response speed, and flow capacity of the solenoid valve directly determine the performance of the entire system.
The WAALPC MVSC Series is a comprehensive family of solenoid valves designed for industrial pneumatic control. With body widths ranging from 180 to 600, valve configurations covering 3/2-way, 5/2-way, and 5/3-way, single and double coil options, and multiple center position functions, the MVSC Series provides a flexible, high-performance solution for virtually any pneumatic directional control requirement.
This guide covers the MVSC Series in detail — ordering code, technical specifications, working principles, flow characteristics, key features, application scenarios, installation, and selection criteria.
The MVSC Series is a family of electromagnetic directional control valves designed for compressed air systems. These valves control the direction of airflow to pneumatic actuators, enabling functions such as extending/retracting cylinders, switching vacuum lines, and controlling grippers.

The MVSC-220 series flow diagram shows the relationship between secondary pressure (MPa) and flow rate (Nl/min) . The curves demonstrate:
At lower flow rates, secondary pressure remains close to the primary pressure
As flow rate increases, secondary pressure drops proportionally
The valve maintains stable regulation across a wide flow range
Different primary pressure lines (0.1–0.8 MPa) are clearly differentiated
This data allows engineers to verify that the valve's flow capacity meets system requirements before installation.
A 3/2-way valve has 3 ports and 2 positions:
Port | Function |
|---|---|
1 (P) | Pressure inlet |
2 (A) | Working port (to actuator) |
3 (R) | Exhaust port |
Operation:
De-energized (NC): P blocked; A connected to R (actuator exhausts)
Energized: P connected to A; R blocked (actuator pressurizes)
A 5/2-way valve has 5 ports and 2 positions:
Port | Function |
|---|---|
1 (P) | Pressure inlet |
2 (A) | Working port 1 |
3 (R) | Exhaust port 1 |
4 (B) | Working port 2 |
5 (R2) | Exhaust port 2 |
Operation:
De-energized: P→A, B→R2 (cylinder extends or retracts depending on connection)
Energized: P→B, A→R (cylinder moves opposite direction)
Spring return: Returns to default position when power is removed
Same port configuration as 4E1, but with two solenoids:
Coil 1 energized: P→A, B→R2
Coil 2 energized: P→B, A→R
Memory function: Valve retains last position when power is removed
A 5/3-way valve has 5 ports and 3 positions. The center position can be configured in three ways:
Center Type | Code | Function | Application |
|---|---|---|---|
Closed Center | C | All ports blocked | Holding actuator mid-stroke |
Pressure Center | P | All ports pressurized | Holding with pressure on both sides |
Exhaust Center | R | All ports exhausted | Releasing actuator, free movement |
Operation:
Coil 1 energized: P→A, B→R
Both coils de-energized (center): Depends on C/P/R configuration
Coil 2 energized: P→B, A→R
The MVSC Series is available in six body widths (180, 220, 260, 300, 460, 600), allowing precise matching of flow capacity to application requirements. This eliminates the need to over-specify or under-specify, optimizing both performance and cost.

Verify the model: Confirm valve type, voltage, port size, and function match your requirements
Check the air supply: Ensure air is filtered (40μm or better) and within pressure range
Inspect the valve: Check for shipping damage
Verify electrical supply: Confirm voltage is within ±10% of coil rating
Mount the valve: Install using the body mounting holes or on a manifold
Connect piping: Follow port markings (P = inlet, A/B = working ports, R/R2 = exhaust)
Apply thread sealant: Use PTFE tape on male threads only, leaving the first thread bare
Tighten connections: Do not overtighten
Match voltage: Confirm coil voltage matches supply
Connect wiring: Follow the wiring diagram for the connector type
Check grounding: Ensure proper grounding for safety
Verify protection: Use appropriate fusing or circuit protection
Do | Do Not |
|---|---|
Use filtered air (40μm or better) | Use unfiltered or contaminated air |
Match voltage to coil specification | Apply incorrect voltage |
Provide clearance for maintenance | Install in confined spaces without access |
Use proper thread sealant | Allow sealant debris to enter the valve |
Depressurize before maintenance | Disassemble under pressure |
Frequency | Task |
|---|---|
Daily | Visual inspection for air leaks; check electrical connections |
Monthly | Verify valve operation; check for unusual noise or heat |
Quarterly | Inspect for signs of wear or contamination |
Annually | Replace seals if showing signs of aging |
Symptom | Possible Cause | Solution |
|---|---|---|
Valve does not shift | No power; incorrect voltage; coil burned out | Check power supply; verify voltage; replace coil |
Air leakage | Damaged seals; loose connections | Replace seals; tighten connections |
Slow response | Low voltage; contaminated air; low pilot pressure | Check power supply; clean/replace filter |
Coil overheats | Incorrect voltage; continuous duty exceeded | Verify voltage; check duty cycle |
Valve chatters | Low voltage; insufficient current | Check power supply |
Internal leakage | Worn spool or seals | Replace valve or service kit |
Manual override not working | Mechanical obstruction | Clean or replace override mechanism |
Air quality: Clean, dry, filtered air extends seal and spool life
Operating frequency: Higher cycling rates accelerate wear
Ambient conditions: Temperature extremes and contaminants reduce life
Power supply: Stable voltage prevents coil damage
Factor | Consideration |
|---|---|
Valve type | 3/2 (3E1), 5/2 single (4E1), 5/2 double (4E2), or 5/3 (4E2 C.P.R) |
Center position | C (closed), P (pressure), or R (exhaust) for 5/3 models |
Body width | 180, 220, 260, 300, 460, or 600 — match to flow requirement |
Port size | G1/8 or G1/4 |
Voltage | AC110V, AC220V, AC24V, DC24V, or DC12V |
Function | NC (normally closed) or NO (normally open) |
