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.

Construction

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.
