Specification Overview:
The MVSP-188 series includes models 4E1, 4E2, and 4E2 C.P.R, designed for air medium with port size Rc1/4. The series offers configurations with 5 ports and either 2 or 3 positions. Operating pressure ranges from 0.15 to 0.7 MPa for model 4E1 and 0.2 to 0.7 MPa for models 4E2 and 4E2 C.P.R, with a proof pressure of 1 MPa.

Performance and Features:
- Effective orifice sizes vary between body ported and manifold types, with response times under 23 ms for DC and 35 ms for AC in model 4E1, and under 33 ms for DC and 45 ms for AC in model 4E2.
- The ambient temperature range is -5 to +50°C, ensuring no freezing conditions.
- Voltage options include AC110V, 220V (50/60Hz), and DC24/12V, with power consumption at 1.12VA for AC and 0.95W for DC.
- Insulation is classified as F class, with weights ranging from 96g to 142g depending on the model.

Ordering Information:
- Manifold and body ported types are available, with specific order codes for different configurations, including solenoid types (single or double), port threads (Rc, G, NPT), and center types (closed, pressure, exhaust).
- Wire length options are available for horizontal connectors, ranging from 500mm to 3000mm.

Flow and Pressure Characteristics:
- Detailed flow rate and pressure graphs are provided, illustrating the relationship between primary and secondary pressures across different flow rates.

Mounting and Assembly:
- The document includes dimensions and assembly instructions for mounting brackets and spacer assemblies, compatible with MVSY models.
- Specific configurations for SUP and EXH ports are detailed, with options for individual or combined spacer assemblies.

Caution:
- It is advised not to apply force to the coil when tightening the tube fitting to avoid damage.
