Dual Solenoid Valve Control - CSM5M-3A | Cla-Val

Cla-Val CSM5M-3A Dual Solenoid Valve Control

The Cla-Val CSM5M-3A is a dual-solenoid pilot control assembly designed for marine fire protection systems, including magazine sprinkling, hangar deck protection, water curtain applications, and elevator shaft foam flooding lines. The unit is specified at 3/8" size with union connections per MIL-F1183 standard.

Functional Role

The CSM5M-3A is not an inline main supply valve. It operates as a dual solenoid control within pilot or remote actuation circuits, where electrical signals modulate the state of pilot lines or remote control valves. System response depends on the hydraulic schematic, actuation logic, and the valve’s integration within the fire suppression circuit.

Technical Application Data

• Type: Dual Solenoid Valve Control
• Size: 3/8"
• Connection: Union MIL-F1183
• Applications: magazine, hangar deck, water curtain, elevator shaft foam flooding
• Media: seawater, AFFF (aqueous film-forming foam)
• Relevant Specification: MIL-V-17501, Type I, Class 1 and 2 – Sea Water Sprinkling Control Valves

Selection Considerations

For technical submittals, confirm the following:

• Coil voltage and type
• Fail-safe position per fire control logic
• Compatibility with control station interface
• Pilot line pressure rating
• Union connection per MIL-F1183
• Suitability for seawater or AFFF service
• Provision for test and isolation access

Maintenance

Inspection should include coil integrity, wiring, union seal tightness, pilot orifice cleanliness, electrical actuation response, and correct reset after testing. For seawater or AFFF service, periodic flushing and inspection for salt, foam residue, or pilot line blockage are required to maintain operational reliability.
