NAVAL Steam Ball Valves

Naval steam ball valves are designed for on-off service. The valves are specially suitable for steam, condensate, hot oil, gas and other non-corrosive media.


The valve has an all-welded body and is fitted with special polymer seats which are long-lasting against frequent operation, impurities and chemicals. A ground and polished stainless steel ball gives easy turning and reliable operation over many years. A floating ball construction is used. Bevel spring washers keep the seats pressed against the ball to ensure that the valve remains tight regardless of pressure fluctuations. The blow-out proof stem is equipped with graphite box sealing.
Naval ball valves are manufactured in accordance with European Pressure Equipment Directive 97/23/EY.

Heavy and unreliable cast components are not used in the construction of the valve body. It is easy to retrofit actuating equipment. Leak tightness is acc. to ISO 5208, rate A.
