Structure

GW Sprinkler provides product sales and technical support from its over 7,000 square metres of modern, purpose-built manufacturing space in Glamsbjerg near Odense in Denmark, one of the most advanced production facilities of its kind in the world.

​

Products & Brands

GW Sprinkler develops, manufactures and markets a broad range of products for use in sprinkler, deluge, water spray and water mist systems. These range from automatic control valves, through water flow and pressure control devices, to water delivery spray nozzles and sprinkler heads. In addition, the company has forged close alliances with manufacturers of specialist components that complement its own. A continuous policy of research and development has enabled the company to maintain its position at the forefront of technology in line with the latest demands of the marketplace. Over the years it has developed numerous innovations and customer-inspired enhancements that have led to water-based fire protection systems becoming ever more effective and affordable.

​

For more than 20 years GW Sprinkler  was the manufacturer of high-end Angus Fire sprinkler products such as "Angus-S" automatic sprinkler heads, "Fyrhed" high velocity nozzles, "Thermospray" medium velocity nozzles and "MJC" (multiple jet control) valves. Since year 2013 the IP-rights for the Angus sprinkler and water spray product range were fully acquired by GW Sprinkler and these products are continuously being manufactured in Denmark - now exclusively under the GW Sprinkler brand name.

​

In year 2000 GW Sprinkler A/S acquired all IP rights, manufacturing and sales of the unique elastomeric sleeve Chubb 300 deluge valve after +15 years of manufacturing by Chubb in UK. This high-end valve series was developed in cooperation with leading off-shore end users to provide a state of the art, heavy duty, low maintenance and reliable deluge water control. The "Chubb valves" have since year 2000 been manufactured by GW Sprinkler - and branded as GW C300.   Quality Assurance

GW Sprinkler operates a Quality Management System certified by the Loss Prevention Certification Board to ISO 9001:2015. All components and finished products are rigorously tested and inspected to ensure consistent reliability and performance. This includes the use of an advanced testing facility that simulates anticipated field conditions. The company''s products meet or exceed industry standards around the world and are variously LPCB, FM and VdS Approved, UL Listed and CE Marked (see product data sheets for details).

ABOUT US

Automatic water control valves

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.

b2.png

Automatic Water Control Valve, with Pressure Control + Pneumatic Actuator

This valve is pneumatically actuated and provides pressure control. This valve is used where a constant downstream pressure and a controlled smooth opening and closing of the deluge water supply is called for. The valve's adjustable restrictors can be set to provide the opening- and closing speed desired, to prevent the damaging effects of reaction forces and water hammer. The valve is fitted with an external pneumatic actuator to facilitate activation from e.g. pilot line air pressure drop. The actuator if fitted with a latch that locks the actuator and deluge valve open when activated, thus requiring manual re-setting to close.

b3.png

Automatic Water Control Valve, Non Regulating with Strainer & Restrictors + Pneumatic Actuator (Latching)

This valve is used where a controlled and smooth opening and closing of the deluge water supply is called for. The valve's adjustable restrictors can be set to provide the opening- and closing speed desired, to prevent the damaging effects of reaction forces and water hammer. The valve is fitted with an external pneumatic actuator to facilitate activation from e.g. pilot line air pressure drop. The actuator is fitted with a latch that locks the actuator and deluge valve open when activated, thus requiring manual re-setting to close.

GW C300 Fluid Control Valve, Pressure Reducing

This valve is used where a constant downstream pressure is required, irrespective of the fire pump pressure. The deluge valve is fitted with a pressure control pilot that constantly monitors the downstream pressure and modulates the C-300 valve elastomeric orifice to open and close and maintain the pre-set downstream pressure.

b5.png

Automatic Water Control Valve, with Pressure Control + Pneumatic Actuator & Solenoid

This valve is both electrically & pneumatically actuated and provides pressure control. This valve is used where a constant downstream pressure and a controlled smooth opening and closing of the deluge water supply is called for. The valve's adjustable restrictors can be set to provide the opening- and closing speed desired, to prevent the damaging effects of reaction forces and water hammer. The valve is fitted with an external heavy duty solenoid and a pneumatic actuator valve to facilitate reliable electrical and/or pneumatic actuation. Both actuators are fitted with a latch that locks the deluge valve open when activated, thus requiring manual re-setting to close.

b7.png

Automatic Water Control Valve, Non regulating with Strainer & Restrictors + Integral Pneumatic Actuator (latching)

This valve is used where a controlled and smooth opening and closing of the deluge water supply is called for. The valve's adjustable restrictors can be set to provide the opening- and closing speed desired, to prevent the damaging effects of reaction forces and water hammer. The valve is fitted with a compact integral pneumatic actuator to facilitate activation from e.g. pilot line air pressure drop. The actuator if fitted with a latch that locks the actuator and deluge valve open when activated, thus requiring manual re-setting to close.
