DELUGE / GW C300 ELASTOMERIC SLEEVE VALVES
The GW C300 Series of deluge valves are specially developed and designed to provide reliable performance even in the most demanding environments such as those encountered on offshore platforms and in the petrochemical industry. The C300 modular construction allows for a large variety of builds/trimmings, from simple on/off valves to advanced actuated pressure regulating versions. The range of GW C300 deluge valves is characterized by:
- Low Friction Loss
- Low Cavitation
- Low Maintenance
- Highly Corrosion Resistant Materials - Nickel Aluminium Bronze / SuperDuplex Cr25 / Titanium
- No moving mechanical parts in contact with water
- Soft start & stop / adjustable opening & closing speed
- Horizontal and Vertical installation
- Wafer design for ANSI 150 or 300# flanges
- Sizes 3" to 12" / Flow 100 to 45.000 lpm
- FM Approval / NORSOK M650
- NFPA 15
The deluge valves in this category all have a means of actuation to control the on/off (open/close) function. Actuation is provided as pneumatic or electrical - or both. These actuated deluge valves come both with and without pressure regulation.
2022 NEW: GW C-300 pressure regulating deluge valves are now FM approved in sizes 3" to 10" with differential pressure as low as 1 bar across the valve.
The deluge valves in this category all have a manually adjustable pilot fitted for easy and accurate setting of the regulated downstream pressure. The max. rated inlet pressure is 20 bar - and the regulated outlet pressure can be set in the range 3 to 15 bar.
GW-S detector heads are used in fixed fire protection deluge systems. The detector head is typically fitted in the pilot line of the deluge valve detection system. When exposed to heat from a fire, the heat-sensitive glass bulb shatters and the detector head goes open. The activated detector releases compressed air from the pilot line, causing a pressure drop which will trip the deluge valve to go open and discharge water through all open spray nozzles to extinguish/control the fire.
