Compact Single Ball Valve

Our Compact Style Single Ball Valves are designed to provide considerable space and weight savings when compared to a traditional flanged end ball valve. Available in both floating and trunnion ball designs, the valve utilises Oliver’s proven ball valve technology and can be supplied with either manual or automated actuation.

Compact Light Weight Design

Provides space and weight saving on platforms, reduced shipping and handling costs and minimal structural support

Threaded Valve Insert

Designed to take full working pressure.  Does not rely on mating flange to hold internals.  

Oliver Swivel Flanges

Designed to allow hubs to be welded into line, before split rings and flanges are fitted.  Valve can be fitted with no additional ‘springing’ of pipework.

Firesafe Design

O-ring seals and metal-to-metal contact on all static joints, graphite rings provide additional resistance to leakage in the event of fire.  

Other Design Features

Anti-blow out stem design shouldering on the body (rather than the bonnet), Automatic cavity relief, Low friction dry stem bearings to minimise operating torques and maximise cycle life.  
Valve can be supplied with mounting plate in accordance with ISO 5211 for actuator attachment.
