Water drain valve series 660

Water drains valves are used when relieving tanks of water accumulated during normal tank breathing. The Protectoseal 660 series are designed to provide maximum flow and assure complete self-draining action.

Internal safety valve series 3000

Internal safety valves are applied on storage tanks containing flammable or combustible liquids. The 3000 series close automatically in case of fire. Consequently they protect the tank and content against the hazards of exposure to fire.

Overflow valve series 7300D

Overflow valves eliminate an open overfill pipe connection into the vapour space of a storage tank. The Protectoseal series 7300D valve provides a sealing of a liquid overfill pipe. It opens as soon as the set point of the valve is reached. This is the case in an overfill situation. The valve is not a primary relief device.
