The international shipbuilding branch requires high-precision advanced components with absolutely reliable function.

Special ambient conditions such as corrosion, vibrations or extreme temperatures place high demands on the ship components. Our valves are designed in such a way that they guarantee perfect functioning in spite of these conditions.

Among other things, the GSR valves are used in the maritime sector in bilge water separators, as start-up valves in diesel engines, for water treatment, in fire-extinguishing systems and in many other applications which require perfect functioning for safe operation.

To prove to our customers that our valves really comply with the challenging specifications, a number of valves from our comprehensive product range of special valves or block valves are certified by the ship classification association Germanischer Lloyd.

Type 2/449

The start process of large diesel engines on ships demands, among other things, valves that let the engine start up reliably.
In this sensitive area of ship drives, valves of type 2/449 are often used. The solenoid valve switches the starting air from compressed air bottles into the starting system of the motor, thus initiating the starting process.

The 3/2 way pilot operated piston solenoid valve with customer-specific connections is designed for a pressure range of 7 to 40 bar. For the demand-ing applications in shipbuilding, the valve is equipped with additional options. This includes a red-anodized manual override for fast locating and switching off the valve.

As a protection against foreign impact, the manual override is additionally equipped with a metal bracket.
Further options are a coupler socket with LED and a safety shutoff valve.

The valve has been designed from the start to prevent clogging of the pilot orifice even under most adverse conditions. The pilot orifice is very large, and a filter is installed in the valve. This prevents soiling from entering the valve there clogging the orifice.

In shipbuilding, our technically high quality valves designed per customer requirements are used in the following ranges of application, among others:

• Bilge water de-oilers
• Startup valve for diesel engines
• Water treatment
• Fire extinguishing systems

Type 2/420 - 2/425

Due to the specific requirements in marine technology, our valve series 2/420 to 2/425 are used, among others.
The direct acting pressure controlled 2/2-way diaphragm valve (also available as 3/2-way valves under the type numbers 2/431 to 2/438) is designed for a pressure range up to 16 bar.
The body material is mainly cast iron, upon request also cast steel or stainless steel.

 This valve is used as oil drain valve in bilge water de-oilers. Due to the sturdy diaphragm design, we can ensure extreme immunity in the media range and a high stability even under the most severe operating conditions

Type 24

The force pilot operated 2/2-way piston solenoid valve of the type 24, suitable for a pressure range of 0-40 bar,

is used as component in a fire extinguishing system.

The valve has been specifically designed for the highly demanding customer application and is equipped with a manual override.

Additionally two position indicators can be offered.
