Water Drain Valve - 100M-1KR | Cla-Val

Cla-Val 100M-1KR Valve for Hydraulic Control of Sprinkler / AFFF Systems

The product page lists this valve as a water drain valve, but the Cla-Val technical datasheet specifies the 100M-1KR as a Remote Control Valve, diaphragm-actuated, designed for hydraulic actuation circuits in shipboard Dry Type Magazine Sprinkler Systems. The datasheet indicates a nominal size of 3/8”.

System Operation

The 100M-1KR is a normally open auxiliary control valve that closes upon application of remote control pressure. It is used in interconnected actuation piping to switch between open-valve loop and closed-loop operation of the magazine sprinkler valve. The datasheet references compatibility with the 81PM-1 hydraulically-actuated check valve.

Technical Selection Data

• Type: Cla-Val 100M-1KR
• Operation: hydraulically actuated remote control valve
• Normal Position: normally open
• Actuation: closes on control pressure
• Size: 3/8”
• Connection: union, per quick reference catalog
• Connection Specification: MIL-F1183
• Applications: AFFF, seawater sprinkler controls, magazine sprinkler systems

Applications

This valve is used in marine fire suppression systems where hydraulic logic control is required, not simple manual isolation:

• AFFF foam systems
• dry type magazine sprinkler systems
• sea water sprinkling control circuits
• local, adjacent, or remote control stations
• actuation circuits with PRPV or three-way manual valves

Pre-Procurement Checklist

Verify exact function on P&ID, normal position, control signal pressure, MIL-F1183 union connection, compatibility with existing 81PM-1/check valves, and military or marine specification requirements.

Maintenance

Inspection should cover seat leakage, diaphragm response, control line cleanliness, union connection condition, and potential fouling in seawater or AFFF circuits.

FAQ

Is this a simple drain valve?
The datasheet describes it as a remote control valve for sprinkler actuation circuits, not a manual drain valve.

Does it have an electric actuator?
No. Actuation is hydraulic via control pressure.
