Quick Closing Valves

Designed to ensure a safe and simple operation. The short height also allows the usage in narrow spaces.

Available in nodular cast iron, cast steel and bronze from DN 15 up to DN 200, both as straight and angle type.

The valves are type approved by ABS, GL, LR, BV and DNV.

Mainly used for sudden blocking of pipe line systems in case of danger and on tanks with combustible liquids. The blocking is done by remote control from outside the danger area.


Butterfly Valves

Designed for use up to max. 25 bar and are available in cast iron, nodular cast iron, cast steel, stainless steel and bronze for pipes from DN 40 up to DN 600. For assembly between flanges acc. to DIN, ANSI or JIS.

Standard working pressure 10 bar (16 bar on request) and High performance butterfly valve 25 bar

Type of Valve :

  • Wafer type and lug type butterfly valves back seated
  • Double flanged type butterfly valves with seat vulcanised to the body
  • High performance butterfly valve with sealing ring double eccentric
The butterfly valves are suitable for fluids, e.g. water, sea water, fuel and oil and are designed for the chemical and petrochemical industries, water and wastewater technology, shipbuilding and civil engineering.


Ball Valves

Fire Fighting Equipment

Couplings, Branchpipes, Nozzles

Couplings in gunmetal, bronze, brass or light alloy. Depending on the system we can make available sizes from 1“ up to 6“.

Branch pipes features a simple, reliable design and they are insensitive to dirt. They achieve a large throw distance and allow fine atomizing of the spray jet or a closed full jet. Spray angle and droplet size can be varied.


Landing Valves, Monitors

Landing Valves are available in gunmetal, bronze or brass. Depending on the system we can offer sizes from DN 25 up to DN 100. Monitors are available in gunmetal in sizes from DN 65 up to DN 150. Operated manual, electrical, or hydraulic and with wireless remote control with Quick shot monitor.
